Schmitt, Maxime. "Génération automatique de codes adaptatifs". Thesis, Strasbourg, 2019. http://www.theses.fr/2019STRAD029.
Texto completoIn this thesis we introduce a new application programming interface to help developers to optimize an application with approximate computing techniques. This interface is provided as a language extension to advise the compiler about the parts of the program that may be optimized with approximate computing and what can be done about them. The code transformations of the targeted regions are entirely handled by the compiler to produce an adaptive software. The produced adaptive application allocates more computing power to the locations where more precision is required, and may use approximations where the precision is secondary. We automate the discovery of the optimization parameters for the special class of stencil programs which are common in signal/image processing and numerical simulations. Finally, we explore the possibility of compressing the application data using the wavelet transform and we use information found in this basis to locate the areas where more precision may be needed
Thiéblin, Elodie. "Génération automatique d'alignements complexes d'ontologies". Thesis, Toulouse 3, 2019. http://www.theses.fr/2019TOU30135.
Texto completoThe Linked Open Data (LOD) cloud is composed of data repositories. The data in the repositories are described by vocabularies also called ontologies. Each ontology has its own terminology and model. This leads to heterogeneity between them. To make the ontologies and the data they describe interoperable, ontology alignments establish correspondences, or links between their entities. There are many ontology matching systems which generate simple alignments, i.e., they link an entity to another. However, to overcome the ontology heterogeneity, more expressive correspondences are sometimes needed. Finding this kind of correspondence is a fastidious task that can be automated. In this thesis, an automatic complex matching approach based on a user's knowledge needs and common instances is proposed. The complex alignment field is still growing and little work address the evaluation of such alignments. To palliate this lack, we propose an automatic complex alignment evaluation system. This system is based on instances. A famous alignment evaluation dataset has been extended for this evaluation

Texto completoSince we are in an era of processor clock stagnation, computing power growth has been relying on parallel computing. More than the algorithmic difficulty involved in any program writing, parallel computing additionally requires the programmer to manage numerous processing units including their tasks and interactions. In order to alleviate the parallel programmer’s burden, this thesis proposes two different approaches for automatic parallel code generation. The bulk-synchronous parallel (BSP) model provides good properties such as its cost model and is therefore chosen as the target of our parallel code generation.Automata and regular expressions are often chosen to model sequential computation and their parallelization will lead to a strong foundation for general parallel code generation. For our main approach, we develop the theory of BSP automata with their generation and determinization. This theory is used in a novel method for parallel regular expression matching.As another approach, we propose a domain specific language for programming neural nets where the functional composition of only a few primitives eases development, maintenance and formal definition of the language compared to existing approaches

Texto completoNext-generation sequencing has enabled researchers to conduct in-depth analyses of the immunological repertoire landscape. However, a significant concern in these studies is the computational cost of analyzing millions of sequences with inherent complexity, variability, and mutational capacity, imposing computational challenges and necessitating the development of efficient methods. This challenge is even more evident in the clinical context that does not necessarily have access to professionals with computing skills or robust computational resources. Thus, the main goal of this thesis is to develop a set of dedicated and integrated tools to be used in the clinical environment, for medical diagnostic and patient care, and in the research environment, to perform large-scale and in-depth repertoire analysis. We have designed and implemented multiple algorithms and gathered them in a user-friendly interactive BCR repertoire visualization pipeline to facilitate the process of integrating BCR repertoire analysis into medical practices

Texto completoOur perspectives are educational, to create grammar exercises for French. Paraphrasing is an operation of reformulation. Our work tends to attest that sequence-to-sequence models are not simple repeaters but can learn syntax. First, by combining various models, we have shown that the representation of information in multiple forms (using formal data (RDF), coupled with text to extend or reduce it, or only text) allows us to exploit a corpus from different angles, increasing the diversity of outputs, exploiting the syntactic levers put in place. We also addressed a recurrent problem, that of data quality, and obtained paraphrases with a high syntactic adequacy (up to 98% coverage of the demand) and a very good linguistic level. We obtain up to 83.97 points of BLEU-4*, 78.41 more than our baseline average, without syntax leverage. This rate indicates a better control of the outputs, which are varied and of good quality in the absence of syntax leverage. Our idea was to be able to work from raw text : to produce a representation of its meaning. The transition to French text was also an imperative for us. Working from plain text, by automating the procedures, allowed us to create a corpus of more than 450,000 sentence/representation pairs, thanks to which we learned to generate massively correct texts (92% on qualitative validation). Anonymizing everything that is not functional contributed significantly to the quality of the results (68.31 of BLEU, i.e. +3.96 compared to the baseline, which was the generation of text from non-anonymized data). This second work can be applied the integration of a syntax lever guiding the outputs. What was our baseline at time 1 (generate without constraint) would then be combined with a constrained model. By applying an error search, this would allow the constitution of a silver base associating representations to texts. This base could then be multiplied by a reapplication of a generation under constraint, and thus achieve the applied objective of the thesis. The formal representation of information in a language-specific framework is a challenging task. This thesis offers some ideas on how to automate this operation. Moreover, we were only able to process relatively short sentences. The use of more recent neural modelswould likely improve the results. The use of appropriate output strokes would allow for extensive checks. *BLEU : quality of a text (scale from 0 (worst) to 100 (best), Papineni et al. (2002))

Texto completoWe address in this thesis the construction of a natural language generation System - computer software that transforms a formal representation of information into a text in natural language. In our approach, we define the generation problem as a constraint satisfaction problem (CSP). The implemented System ensures an integrated processing of generation operations as their different dependencies are taken into account and no priority is given to any type of operation over the others. In order to define the constraint satisfaction problem, we represent the construction operations of a text by decision variables. Individual operations that implement the same type of minimal expressions in the text form a generation task. We classify decision variables according to the type of operations they represent (e. G. Content selection variables, document structuring variables. . . ). The linguistic rules that govern the operations are represented as constraints on the variables. A constraint can be defined over variables of the same type or different types, capturing the dependency between the corresponding operations. The production of a text consists of resolving the global System of constraints, that is finding an evaluation of the variables that satisfies all the constraints. As part of the grammar of constraints for generation, we particularly formulate the constraints that govern document structuring operations. We model by constraints the rhetorical structure of SORT in order to yield coherent texts as the generator's output. Beforehand, in order to increase the generation capacities of our System, we extend the rhetorical structure to cover texts in the non-canonical order. Furthermore, in addition to defining these coherence constraints, we formulate a set of constraints that enables controlling the form of the macrostructure by communicative goals. Finally, we propose a solution to the problem of computational complexity of generating large texts. This solution is based on the generation of a text by groups of clauses. The problem of generating a text is therefore divided into many problems of reduced complexity, where each of them is concerned with generating a part of the text. These parts are of limited size so the associated complexity to their generation remains reasonable. The proposed partitioning of generation is motivated by linguistic considerations

Texto completoASIPs (/Application Specific Instruction set Processors/) are custom processors that offer a good trade-off between performance and flexibility. A common processor customization approach is to augment its standard instruction set with application-specific instructions that are implemented on specifically designed hardware extensions (reconfigurable cells). These extensions are often directly connected to the processor's data-path. The design of the ASIP processor must rely on dedicated methodologies and software tools that manage both the design constraints and the growing complexity of applications. In this context, the aims of this thesis were to propose a new methodology for the automatic generation of instruction-set extensions. In the first step of our proposed design flow, we generate the instruction candidates that satisfy some architectural and technological constraints. In the second step, we identify the set of standard and customized instructions that minimizes the sequential application's execution time. In the next step, optimized hardware extensions and the corresponding application program including new instructions are generated. During the hardware generation, the optimizations of the hardware resources such as registers and multiplexers are simultaneously carried out. In our proposed design flow we used the constraint-based approach to solve the computationally complex problems of instruction identification, instruction selection and register allocation

Texto completoIn this work, we explore how Natural Language Generation (NLG) techniques can be used to address the task of (semi-)automatically generating language learning material and activities in Camputer-Assisted Language Learning (CALL). In particular, we show how a grammar-based Surface Realiser (SR) can be usefully exploited for the automatic creation of grammar exercises. Our surface realiser uses a wide-coverage reversible grammar namely SemTAG, which is a Feature-Based Tree Adjoining Grammar (FB-TAG) equipped with a unification-based compositional semantics. More precisely, the FB-TAG grammar integrates a flat and underspecified representation of First Order Logic (FOL) formulae. In the first part of the thesis, we study the task of surface realisation from flat semantic formulae and we propose an optimised FB-TAG-based realisation algorithm that supports the generation of longer sentences given a large scale grammar and lexicon. The approach followed to optimise TAG-based surface realisation from flat semantics draws on the fact that an FB-TAG can be translated into a Feature-Based Regular Tree Grammar (FB-RTG) describing its derivation trees. The derivation tree language of TAG constitutes a simpler language than the derived tree language, and thus, generation approaches based on derivation trees have been already proposed. Our approach departs from previous ones in that our FB-RTG encoding accounts for feature structures present in the original FB-TAG having thus important consequences regarding over-generation and preservation of the syntax-semantics interface. The concrete derivation tree generation algorithm that we propose is an Earley-style algorithm integrating a set of well-known optimisation techniques: tabulation, sharing-packing, and semantic-based indexing. In the second part of the thesis, we explore how our SemTAG-based surface realiser can be put to work for the (semi-)automatic generation of grammar exercises. Usually, teachers manually edit exercises and their solutions, and classify them according to the degree of dificulty or expected learner level. A strand of research in (Natural Language Processing (NLP) for CALL addresses the (semi-)automatic generation of exercises. Mostly, this work draws on texts extracted from the Web, use machine learning and text analysis techniques (e.g. parsing, POS tagging, etc.). These approaches expose the learner to sentences that have a potentially complex syntax and diverse vocabulary. In contrast, the approach we propose in this thesis addresses the (semi-)automatic generation of grammar exercises of the type found in grammar textbooks. In other words, it deals with the generation of exercises whose syntax and vocabulary are tailored to specific pedagogical goals and topics. Because the grammar-based generation approach associates natural language sentences with a rich linguistic description, it permits defining a syntactic and morpho-syntactic constraints specification language for the selection of stem sentences in compliance with a given pedagogical goal. Further, it allows for the post processing of the generated stem sentences to build grammar exercise items. We show how Fill-in-the-blank, Shuffle and Reformulation grammar exercises can be automatically produced. The approach has been integrated in the Interactive French Learning Game (I-FLEG) serious game for learning French and has been evaluated both based in the interactions with online players and in collaboration with a language teacher

Texto completoFuzzy inference system (FIS) synthesis for identification and control of MIMO systems represents a non trivial research problematic which requires a knowledge base generation methodology. The aim of this thesis is to propose a new algorithmic for automatic induction of MIMO fuzzy controllers. For this purpose, a neuro-fuzzy hybrid model is used to model the FIS, due to its structure unicity. The proposed approach includes two main steps. The first one concerns the model parameters identification using a back-propagation method. The second one consists of an optimization of the FIS structure based on a new classification algorithmic. A new formulation of the FCM (Fuzzy C-Means) clustering method, tacking into account a new constraint based on a fuzzy sets inclusion index from similarity point of view, is proposed. This approach has been validated on two applications. The first one concerns the dynamic control of a 2-DOF serial robot and the second one, the free space non-linear efforts identification of a C5 parallel robot. The obtained performances show a good approximation accuracy of a non-linear MIMO system. Moreover, this approach has allowed the reduction of the generated fuzzy rules number with a factor of 10, compared to the FCM approach using a grids partition

Texto completoThis PhD work focuses on the evaluation of learning and especially the automatic generation of evaluation topics in universities. We rely on a base of source questions to create topic questions through algorithms that are able to construct differentiated assessment tests. This research has made it possible to develop a metric that measures this differentiation and to propose algorithms aimed at maximizing total differentiation on test collections, while minimizing the number of necessary patterns. The average performance of the latter depends on the number of patterns available in the source database (compared to the number of items desired in the tests), and the size of the generated collections. We focused on the possible differentiation in very small collections of subjects, and proposes methodological tracks to optimize the distribution of these differentiated subjects to cohorts of students respecting the constraints of the teacher. The rest of this work will eventually take into account the level of difficulty of a test as a new constraint, relying in part on the statistical and semantic data collected after each test. The goal is to be able to maximize the differentiation by keeping the equity between the Tests of a Collection, for an optimized distribution during the Events

Texto completoFace a cette problématique, nous proposons dans cette thèse pour le contexte relationnel, une approche de génération automatique de requêtes de médiation. A partir de la description d'un ensemble de sources de données distribuées et hétérogènes et de méta-données, notre algorithme produit un ensemble de requêtes de médiation possibles. Nous avons développé un outil qui permet de générer automatiquement des requêtes de médiation dans un environnement hétérogène. Notre objectif principal étant de fournir à l'utilisateur un outil adapté aux petits et grands systèmes, nous avons réalisé une série de tests d'évaluation des performances pour mesurer son passage à l'échelle. Ces tests montrent la faisabilité de notre approche.

Texto completoAbstract : Because collaborative robots are aimed at working in the vicinity of human workers without physical security fences, they bring new challenges about security. Even if robots can be conceived to be less harmful, their software has to integrate security features in order to be suitable for dynamic human environments. Since classical path planning algorithms require heavy calculations, it is interesting to modify the trajectory in real time to adapt it to the dangerous environment. In this research project, an inverse kinematics solver, in the form of an optimization problem, is used to generate the command of the robot to follow a trajectory defined offline. The addition of security constraints is studied: first, the manipulability index, which reflects the distance of the robot to singular configurations, is considered. Thus, it should be maximized all along the trajectory to ensure the best mobility available. Then the human is integrated by taking into account its comfort: in order to reduce the stress of working near an unpredictable moving robot, the distance between the end-effector and the human gaze is minimized to guarantee a greater visibility of the task. In both cases, we have presented a new formulation of those criteria to integrate them into the optimization problem. Moreover, the collision avoidance constraint is used, as well as the trajectory relaxation, which allows the robot to deviate from its trajectory for a certain amount of time during the task. Finally tests in simulation and with the real Baxter robot from Rethink Robotics validated our approach and the performance has been evaluated in real conditions, using a RGB-D camera and a real time human tracker software.

Texto completoThis thesis work done in the context of the FUI project Minalogic Bluesky, concerns the automated functional testing of a particular class of programmable logic controllers (em4) produced by InnoVista Sensors. These are synchronous systems that are programmed by means of an integrated development environment (IDE). People who use and program these controllers are not necessarily expert programmers. The development of software applications should be as result simple and intuitive. This should also be the case for testing. Although applications defined by these users need not be very critical, it is important to test them adequately and effectively. A simulator included in the IDE allows programmers to test their programs in a way that remains informal and interactive by manually entering test data.Based on previous research in the area of synchronous test programs, we propose a new test specification language, called SPTL (Synchronous Testing Programs Language) which makes possible to simply express test scenarios that can be executed on the fly to automatically generate test input sequences. It also allows describing the environment in which the system evolves to put conditions on inputs to arrive to realistic test data and limit unnecessary ones. SPTL facilitates this testing task by introducing concepts such as user profiles, groups and categories. We have designed and developed a prototype named "Testium", which translates a SPTL program to a set of constraints used by a Prolog solver that randomly selects the test inputs. So, generating test data is based on constraint logic programming techniques.To assess this, we experimented this method on realistic and typical examples of em4 applications. Although SPTL was evaluated on EM4, its use can be envisaged for the validation of other types of synchronous controllers or systems

Texto completoOur study mainly concerns the definition of structure of process-planning knowledge and their use by an expert system SAGGA. The different process-planning belonging to such family are you represented by an oriented graph where the nodes are the operations and the branches the geometrical conditions and technical conditions to perform these operations. This graph defines manufacturing process model for the product family. On mathematical point of view, this model is described according to a particular Petri network are the stages and the manufacturing conditions some transitions. The properties of this network called Grafcet which is used in sequential systems control. The graph representing the manufacturing model is defined by productions rules written in an internal language. The expert system then produces the process-planning corresponding to the new product, from part code number and additional information given by user. If the proposed process-planning is not satisfactory, the user may modify then using rules written in an internal language. These rules are then translated in internal language and upted the family knoledge base. Post processor completed the operations defined by the process-planning. It uses an iterative display with technological table and takes into account manufacturing constraints

Texto completoPurpose of the presented work is to find a new automatic elaboration methodology of manufacturing ranges based on a totality of coherent concepts. This problem that concerns the integration to know-how be very complex and strongly coupled held account relative constraints to possible procedures and the diversity of resources. This implies the elaboration of an open system' so as to allow the well-off introduction of specific rules to a given environment. We have not sought to modelize the reasoning of the planner because for each agent corresponds a specific step. By situating at the endorsement of a volumetric modeler oriented object (feature), the researched coherence has been obtained in the framework of a systemic approach considering simultaneously product and specifications, process and methodologies , machines and kits. The generalization of the notion of entity to the different applications) the meter of resources, the introduction of balancing criteria allow the elaboration of an adaptable product to the industrial context diversity. The automatic generation system is realized around a specific inference engine so as to limit the combined explosion by associating several rules under an alone constraint of precedence

Texto completoOur work is a contribution on the automatic generation of process planning studies, for prismatic machined parts. Realising of different types of holes is considered by using cutting tools (punching, laser, etc. . . ). The main objective has been to develop a specific methodology of operation for machining a different type of holes (smooth, multi-diameter,. . . ) by using a volumic solid modeler. After a bibliographic study on Computer-Aided Design (CAD), Computer-Aided Manufacturing (CAM) and Computer Aided Process Planning (CAPP) which is the vital link between design and manufacturing. As a variant CAPP approach cannot cope with the desire for complete manufacturing automatic, the generative approach has been considered, this approach is the logical creation of a process planning from the information available in a manufacturing data base without intervention by the planner. An expert system that encodes machining practice is used to generate drilling sequence. We have established a knowledge-based representation in the form of production rules to define operations sequences and using machine and cutting tools correspond to surface type, dimension tolerance, and roughness. The optimisation of drilling process is studied in detail, where the optimisation signifies minimising the sum of machining travel and set-up times required to perform ail of drilling operations used for producing a different type of holes

Texto completoWithin the field of Reinforced Concrete (RC) structures and more specifically, at the design of non-flexural elements such as corbels, nibs, and deep beams, the rational procedure of conception and justification referred as Strut-and-Tie Method (STM) has shown some advantages over classical algorithms of reinforcement computation based on FE analysis (eg. Wood-Armer or Capra-Maury).The STM remains a suitable alternative for the design of concrete structures presenting either elastic or plastic behaviour whose application framework is well defined in concrete structures’ design codes like the EuroCodes and the AASHTO-LRFD Bridge Design Specifications.Nevertheless, this method has the main inconvenient of requiring a high amount of resources investment in terms of highly experienced personal or in terms of computational capacity for, respectively, its manual application or an automatic approach through topology optimisation.The document proposes a light alternative, in terms of required iterations, to the automation of the STM, which starts from the statement that the resultant struts and ties of a suitable ST model can be distributed according to the direction of the principal stresses, $sigma_{III}$ and $sigma_{I}$ , obtained from a planar or a three-dimensional FE model

Texto completoThis thesis adresses the problem of automatic test case generation for testing the conformance of a reactive implementation. We first propose a methodology which extends the testing theory based on the ioco conformance relation by distinguishing three levels of description: properties, specification and implementation. The methogology integrates verification and conformance testing. The execution of the generated test cases on the implementation allows detecting conformance violations between implementation and specification, but also violation/satisfaction of the properties by the implementation or the specification. Secondly, we introduce a more expressive specification model: recursive interprocedural specifications. The test generation method we propose is based on coreachability analysis, which allows deciding whether and how the test purpose can still be satisfied. However, although it is possible to carry out an exact analysis, the inability of test cases to inspect their own stack prevents them from fully using the coreachability information. We discuss this partial observation problem, its consequences, and how to minimise its impact. Finally, we experiment these methods of test generation on several examples and a case study

Texto completoDeep submicron technologies have increased the challenges in circuit designs due to geometry shrinking, power supply reduction, frequency increasing and high logic density. One of the goals of this thesis is to develop EDA tools able to cope with these DSM challenges. This thesis is divided in two major contributions. The first contribution is related to the development of a new methodology able to generate optimized circuits in respect to timing and power consumption. A new design flow is proposed in which the circuit is optimized at transistor level. The second contribution of this thesis is related with the development of techniques for radiation-hardened circuits. The Code Word State Preserving technique is used to apply timing redundancy into latches and flipflops. Further, a new transistor sizing methodology for Single Event Transient attenuation is proposed. The sizing method is based on an analytic model. The model considers independently pull-up and pull-down blocks

Texto completoNowadays, mediation systems are widely used. However, their implementation raises several problems, especially, the definition of queries when there is a high number of sources, and a great amount of meta data. Furthermore, the problem is particularly important when sources are heterogeneous. We propose in this thesis an approach to automatically generate the mediation queries, in a relational context. Our algorithm produce candidate set of queries since heterogeneous and distributed sources. We develop a tool to automatically generate mediation queries in the heterogeneous context. Our principal goal is to provide an appropriate tool for different sizes of systems; we achieve tests series to perform scalability

Texto completoIn both parts of this thesis, we use automata to solve in a decentralised manner some graphs problems, i. E. The automata do not have a global vision of the graph in which they move, and each automaton makes local decisions using the information available on the node on which it stands. We study the impact of this information on the number of automata or the memory (state, whiteboard) that are necessary for the resolution of the problem. In the first part, we consider some methods of generation of linear algorithms that have been proposed in the literature to solve the problems expressed in monadic second order logic on graphs of bounded treewidth or of bounded cliquewidth. Although the generated algorithms are linear, the multiplicative constant of these algorithms can be very large, making them difficult to use. We have nevertheless implemented a method of generation based on the automata, and we have proved that, for a certain number of properties, the algorithms obtained are usable in practice. In the second part, we consider the problem of distributed graph searching. In a given graph, the goal is that a team, using a minimum number of searchers who calculate their own strategy, capture a fugitive arbitrarily fast and invisible. We study the compromise between the number of searchers and the quantity of information to provide on the environment to capture the fugitive

Texto completoThe work presented in this thesis aim at facilitating the development of resources for natural language processing. Resources of this type take different forms, because of the existence of several levels of linguistic description (syntax, morphology, semantics, . . . ) and of several formalisms proposed for the description of natural languages at each one of these levels. The formalisms featuring different types of structures, a unique description language is not enough: it is necessary to create a domain specific language (or DSL) for every formalism, and to implement a new tool which uses this language, which is a long a complex task. For this reason, we propose in this thesis a method to assemble in a modular way development frameworks specific to tasks of linguistic resource generation. The frameworks assembled thanks to our method are based on the fundamental concepts of the XMG (eXtensible MetaGrammar) approach, allowing the generation of tree based grammars. The method is based on the assembling of a description language from reusable bricks, and according to a unique specification file. The totality of the processing chain for the DSL is automatically assembled thanks to the same specification. In a first time, we validated this approach by recreating the XMG tool from elementary bricks. Some collaborations with linguists also brought us to assemble compilers allowing the description of morphology and semantics

Texto completoLa communication entre systèmes d'information d'entreprise joue un rôle central dans l'évolution des processus d'affaire. Pourtant l'intégration des données reste compliquée : elle exige un effort humain considérable, surtout pour les connexions d'applications appartenant à différentes entreprises. Dans notre recherche nous affirmons que les technologies du Web Sémantique, et plus particulièrement les ontologies, peuvent permettre l'obtention de la flexibilité nécessaire. Notre système permet de surmonter certains manques dans l'état de l'art actuel et réalise une nouvelle approche pour la génération automatique d'ontologies à partir de sources XML. Nous montrons l'utilité du système en appliquant notre théorie au domaine du B2B pour produire automatiquement des ontologies de qualité et d’expressivité appropriée

Texto completoIn a competitive environment with short-life productsand a growing need for customization, the level of flexibility added to production facilities is a key factor in ensuring business competitiveness. In order to manage such production systems, certain tools helping the decision making process have been gradually coming into sight. These tools, such as the Decision Support Systems (DSS) atthe operational level, follow the same logic of increasing complexity of the system for which they are used. To accomplish their role, DSS need data from the production system in order to know the state of the system and make a proper decision. Due to these increased complexity in today’s systems, the necessary information for the DSS is no longer as easily identified as before. Thus theproblems of implementation and integration of DSS begin to appear. Cardin has proposed the use of the observer to solve the integration problem of DSS, however, this solution suffers of a design complexity problem. These studies try therefore to propose an approach to simplify the process of designing the observer. For this reason, the first chapter presents the context control of production systems addressing control structures, approaches on decision making and DSS. The second chapter focuses on the issue of DSS’s data collection and formalizes different approaches found in literature. The third chapter will review the literature on automatic generation of both; control and simulation. The fourthchapter focuses on the proposed approach for the automatic generation of the observer, first in a generic manner then adapted to conveying systems. The last chapter validates the approach through its performance in an actual utilization case

Texto completoThis thesis discusses the use of bandit methods to solve the problem of training extractive abstract generation models. The extractive models, which build summaries by selecting sentences from an original document, are difficult to train because the target summary of a document is usually not built in an extractive way. It is for this purpose that we propose to see the production of extractive summaries as different bandit problems, for which there exist algorithms that can be leveraged for training summarization models.In this paper, BanditSum is first presented, an approach drawn from the literature that sees the generation of the summaries of a set of documents as a contextual bandit problem. Next,we introduce CombiSum, a new algorithm which formulates the generation of the summary of a single document as a combinatorial bandit. By exploiting the combinatorial formulation,CombiSum manages to incorporate the notion of the extractive potential of each sentence of a document in its training. Finally, we propose LinCombiSum, the linear variant of Com-biSum which exploits the similarities between sentences in a document and uses the linear combinatorial bandit formulation instead

Texto completoNatural Language Generation (NLG) is the natural language processing task of generating natural language from a machine representation system. In this thesis report, we present an architecture of NLG system relying on statistical methods. The originality of our proposition is its ability to use a corpus as a learning resource for sentences production. This method offers several advantages : it simplifies the implementation and design of a multilingual NLG system, capable of sentence production of the same meaning in several languages. Our method also improves the adaptability of a NLG system to a particular semantic field. In our proposal, sentence generation is achieved trough the use of sentence models, obtained from a training corpus. Extracted sentences are abstracted by a labelling step obtained from various information extraction and text mining methods like named entity recognition, co-reference resolution, semantic labelling and part of speech tagging. The sentence generation process is achieved by a sentence realisation module. This module provide an adapted sentence model to fit a communicative intent, and then transform this model to generate a new sentence. Two methods are proposed to transform a sentence model into a generated sentence, according to the semantic content to express. In this document, we describe the complete labelling system applied to encyclopaedic content to obtain the sentence models. Then we present two models of sentence generation. The first generation model substitute the semantic content to an original sentence content. The second model is used to find numerous proto-sentences, structured as Subject, Verb, Object, able to fit by part a whole communicative intent, and then aggregate all the selected proto-sentences into a more complex one. Our experiments of sentence generation with various configurations of our system have shown that this new approach of NLG have an interesting potential

Texto completoThe aim of this work is to quickly generate good quality models of the human body. We created a method package which generates finite element meshes from pictures of serial slices (taken from anatomic slices, X-ray sanner or MRI). The mesh generation is divided into three main steps : contours detection, 3D reconstruction and meshing. Contour detection methods were chosen to be applicable on a wide range of pictures. 3D reconstruction and meshing methods are new and based on an octahedral lattice. They allow to generate quadrangular or hexahedral elements. The heads organs were chosen to validate the package. We studied other organs too but these work are just given here as examples
