Повний текст джерелаThe search for interesting groups in boolean data (sets of objects described by sets of properties) has motivated the design of methods for computing global patterns (e. G. . , partitions), and extracting local patterns s(e. G. , frequent itemsets, association rules, formal concepts. This thesis concerns co-clustering, i. E. , computing bi-partitions (coupled partitions on both dimensions). When using available co-clustering algorithms, the user can hardly exploit his/her domain knowledge since he/she has limited possibilities for setting just a few parameters. On the other hand, classical local pattern mining techniques usually provide huge collections of patterns that are hard to evaluate and interpret. We have designed a new co-clustering framework which computes a bi-partition by starting from collections of patterns that capture locally strong associations (e. G. , formal concepts, delta-bi-set that are a form of fault-tolerant patterns). The idea is that the available information about the local patterns can be exploited to build a relevant global pattern. It becomes possible to consider the declarative specification of constraints on the bi-partitions (e. G. , user-defined requirements about the shape of clusters) and to use such constraints at the local pattern mining step and then during the co-clustering phase. As such, our proposal is a contribution to the recent domain of constraint-based clustering. A dual approach consists in using local patterns to interpret bi-partitions. We propose a method for bi-cluster characterization by means of local patterns and their associated interestingness measures. The application of our methods to a gene expression data analysis scenario has illustrated the added-value of our proposal to give rise to plausible biological hypothesis

Повний текст джерелаThe present work was written as part of a cooperative doctorate between the TU Dresden and the University of Applied Sciences Mittweida. In the doctoral thesis, novel, computer-oriented approaches for the analysis of membrane proteins are presented. Membrane proteins are essential for many cellular processes and are important targets for a wide range of pharmaceuticals. Their sequences provide valuable and partly not yet decoded information about their three-dimensional structure and functional characteristics. The analysis of membrane proteins is an important part for the understanding of complex biological processes in the context of proteomics and genomics. Research of membrane proteins revealed a large number of short, distinct sequence motifs. The motifs found so far support the understanding of the folded protein in the Membrane environment. In this dissertation, in three different approaches it is shown how the output of sequence motif-based methods can support the understanding of structural and functional properties of membrane proteins. In general, the junction of proteomic and mutagenic information is intensified. Last but not least, the results of this work are made available for the planning of in vitro experiments as well as for further works in the field of membrane Protein analysis

Повний текст джерелаIn this thesis, our aim is to achieve better results in several tasks in computer vision by focusing on the image representation part. Our idea is to integrate feature dependencies to the original feature representation. Although feature dependencies can give additional useful information to discriminate images, it is a nontrivial task to select a subset of feature combinations from the power set of the features which has an excessively large cardinality. We employ pattern mining techniques to efficiently produce a tractable set of effective combinations. Pattern mining is a process that can analyze large quantities of data and extract interesting patterns such as groups of data records (cluster analysis), unusual records (anomaly detection) and dependencies (association rule mining). The first encountered problem is how to encode image features which are typically real valued as binary transaction items suitable for pattern mining algorithms. We propose some solutions based on local thresholding. The number of extracted patterns is still very high and to use them directly as new features for inferring a supervised classification models leads to overfitting. A solution by aggregating the patterns and have a compact representation which does not overfit to the training data is presented. We have achieved state-of-the-art results on several image classification benchmarks. Along the path of exploration, we realize pattern mining algorithms are suitable especially for large scale tasks as they are very efficient and scale gracefully to the number of images. We have found two suitable applications. The first one is to detect groups of duplicates in very large dataset. In order to run our experiment, we created a database of one million images. The images are randomly downloaded from Google. We have discovered the duplicate groups in less than three minutes. Another application that we found suitable for applying pattern mining techniques is image re-ranking. Our method can improves the original ranking score by a large margin and compare favorably to existing approaches

Повний текст джерелаA change of perspective in the classification of andean textile structures reveals the logic of the system they embody. It also leads to hypotheses as to the social or symbolic meaning of reversible textiles, to the specific geographical distribution of warp-patterned and weft-patterned structures; and to the possible ethnic significance of some twill-derived structures. This classification sustains an analysis of the influence of structures on the designs they make possible. In one particular case, the designs are so "marked" by the technical constraints proper to textile construction that it is possible to recognize them expressed in other media, even when changes in scale make their decoding difficult

Повний текст джерелаThis thesis is part of the data mining applied to ancient handwritten music scores and aims at a search for frequent melodic or rhythmic motifs defined as repetitive note sequences with characteristic properties. There are a large number of possible variations of motifs: transpositions, inversions and so-called "mirror" motifs. These motifs allow musicologists to have a level of in-depth analysis on the works of a composer or a musical style. In a context of exploring large corpora where scores are just digitized and not transcribed, an automated search for motifs that verify targeted constraints becomes an essential tool for their study. To achieve the objective of detecting frequent motifs without prior knowledge, we started from images of digitized scores. After pre-processing steps on the image, we exploited and adapted a model for detecting and recognizing musical primitives (note-heads, stems...) from the family of Region-Proposal CNN (RPN) convolution neural networks. We then developed a primitive encoding method to generate a sequence of notes without the complex task of transcribing the entire manuscript work. This sequence was then analyzed using the CSMA (Constraint String Mining Algorithm) approach designed to detect the frequent motifs present in one or more sequences, taking into account constraints on their frequency and length, as well as the size and number of gaps allowed within the motifs. The gap was then studied to avoid recognition errors produced by the RPN network, thus avoiding the implementation of a post-correction system for transcription errors. The work was finally validated by the study of musical motifs for composers identification and classification

Повний текст джерелаPattern discovery is an important field of Knowledge Discovery in Databases.This work deals with the extraction of minimal emerging patterns. We propose a new efficientmethod which allows to extract the minimal emerging patterns with or without constraint ofsupport ; unlike existing methods that typically extract the most supported minimal emergentpatterns, at the risk of missing interesting but less supported patterns. Moreover, our methodtakes into account the absence of attribute that brings a new interesting knowledge.Considering the rules associated with emerging patterns highly supported as prototype rules,we have experimentally shown that this set of rules has good confidence on the covered objectsbut unfortunately does not cover a significant part of the objects ; which is a disavadntagefor their use in classification. We propose a prototype-based selection method that improvesthe coverage of the set of the prototype rules without a significative loss on their confidence.We apply our prototype-based selection method to a chemical data relating to the aquaticenvironment : Aquatox. In a classification context, it allows chemists to better explain theclassification of molecules, which, without this method of selection, would be predicted by theuse of a default rule

Повний текст джерелаBrotherly rivalry (a common theme in tales) represents a good plot in many American films. To examine the genesis and expression of brotherly rivalry in the cinema, we concentrate our research on literature, religion, myths and American civilization. The study of the mythical origins of these two characters, of the religious symbolism they are associated with, and their evolution within literature helps us to understand the issues which are at stake when two opposing brothers are mentioned. Several films use the wealth of the brotherly rivalry in order to illustrate historical, cultural and social conflicts. Four characteristical films of this particular approach to the seventh art confirm this resurgence of ancestral archetypes in a contemporary context: “Duel in the sun” by King Vidor, “Sabrina” by Billy Wilder, “East of Eden” by Elia Kazan, “Home from the hill” by Vincente Minnelli

Повний текст джерелаThe ARCADIA project aims to develop an automatic method for analyzing engraved decorations on ceramic sherds to facilitate the interpretation of this archaeological heritage. It is to replace the manual and tedious procedure carried out by the archaeologist since the corpus increased to more 38000 sherds. The ultimate goal is to grouping all the decorations created with the same wheel by a poter. We developped a complete chain from the 3Dscanning of the sherd to the automatic classification of the decorations according to their style (diamonds, square, chevrons, oves, etc). In this context, several contributions are proposed implementing methods of image analysis and machine learning. From the 3Dpoint cloud, a depth map is extracted and an original method is applied to automatically detect the salient region centered onto the decoration. Then, a new descriptor, called Blob-SIFT, is proposed to collect signatures only in the relevant areas and characterize the decoration to perform the classification. This approach adapted to each sherd, allows both to reduce significantly the mass of data and improve classification rates. We also use deep learning, and propose an hybrid approach combining local features extracted by Blob-SIFT with global features provided by deep learning to increase the classification performance

Повний текст джерелаClustering is the process of partitioning a dataset into groups, so that the instances in the same group are more similar to each other than to instances in any other group. Many clustering algorithms were proposed, but none of them proved to provide good quality partition in all situations. Consensus clustering aims to enhance the clustering process by combining different partitions obtained from different algorithms to yield a better quality consensus solution. In this work, a new consensus clustering method, called MultiCons, is proposed. It uses the frequent closed itemset mining technique in order to discover the similarities between the different base clustering solutions. The identified similarities are presented in a form of clustering patterns, that each defines the agreement between a set of base clusters in grouping a set of instances. By dividing these patterns into groups based on the number of base clusters that define the pattern, MultiCons generates a consensussolution from each group, resulting in having multiple consensus candidates. These different solutions are presented in a tree-like structure, called ConsTree, that facilitates understanding the process of building the multiple consensuses, and also the relationships between the data instances and their structuring in the data space. Five consensus functions are proposed in this work in order to build a consensus solution from the clustering patterns. Approach 1 is to just merge any intersecting clustering patterns. Approach 2 can either merge or split intersecting patterns based on a proposed measure, called intersection ratio

Повний текст джерелаDuring this thesis, we consider the exhaustive graph mining problem for a special kind of graphs : the grids. Theses grids can be used to model objects that present a regular structure. These structures are naturally present in multiple board games (checkers, chess or go for instance) or in ecosystems models using cellular automata. It is also possible to find this structure in a lower level in images, which are 2D grids of pixels, or even in videos, which are 2D+t spatio-temporal grids of pixels. In this thesis, we proposed a new algorithm to find frequent patterns dedicated to spatio-temporal grids, GriMA. Use of regular grids allow our algorithm to reduce the complexity of the isomorphisms test. These tests are often use by generic graph mining algorithm but because of their complexity, they are rarely used on real data. Two applications were proposed to evaluate our algorithm: image classification for 2D grids mining and prediction of cellular automata for 2D+t grids mining

Повний текст джерелаOur laboratory has developed from many years a serotoninergic chemolibrary (ATBI program). This chemolibrary contains more than 1500 compounds tested toward the most recently discovered receptors: 5-HT4R, 5-HT5R, 5-HT6R and 5-HT7R. We report here several works carried out in the context of ATBI datasets analysis. After a brief introduction we develop the most important biological aspect of serotoninergic system (chapter II). In chapter III, we deal with evaluation and determination of optimal clustering protocols in relation with our internal chemolibrary. Because a good clustering classification for two of our ATBI datasets is really an issue (5-HT6 and 5-HT7) and in order to understand the reasons, we have developed a new method to extract 2D topological pharmacophores using emerging patterns (chapter IV) and built homology models to study binding mode of 5-HT6 ligands (chapter V). Finally we show how a single amino acid (F7. 38) can explain interspecies (human/rat) selectivity ligands of 5-HT7Rs using homology modelling and site-directed mutagenesis (chapter V)

Повний текст джерелаIn this thesis, we deal with the identification of systems and the extraction of patterns from data. In the context of system identification, we focus precisely on the identification of hybrid systems and the identification of linear systems using binary sensors. Two very popular classes of hybrid systems are switched linear systems and piecewise affine systems. First, we give an overview of the different approaches available in the literature for the identification of these two classes. Then, we propose a new real-time identification algorithm for switched linear systems, it's based on an Outer Bounding Ellipsoid (OBE) type algorithm suitable for system identification with bounded noise. We then present several extensions of the algorithm either for the identification of piecewise affine systems, the identification of switched linear systems described by an output error model and the identification of MIMO switched linear systems. After this, we address the problem of the identification of linear systems using binary sensors by introducing an original point of view. We formulate the identification problem as a classification problem. This formulation allows the use of supervised learning algorithms such as Support Vector Machines (SVMs) for the identification of discrete time systems and the identification of continuous-time systems using binary sensors. In the context of pattern extraction, we first present an overview of the different pattern extraction algorithms and clustering techniques available in the literature. Next, we propose an algorithm for extracting patterns from data based on clustering techniques

Повний текст джерелаA mirror, product and vector of a community consciouness, the oral culture of ancienne lande has been immortalized by an outstanding ethnographer : felix arnaudin. Under the influence of a vision and a literary style, the mythical era touches the chronological past and the customary fact, thus underlying the rich diversity og genres and the unity of an anthology in which the supernaturel, esoterism and history are closely interwoven. The study of the interactions between the narrative and the context reveals two essential characteristics of the tales : the integration and the power of social control. These two movements are illustrated, among other things, by the local assimilation of a national literary heritage ("bibliotheque bleue de troyes"). Through this constant struggle for self-assertion, the oral tradition and the protection of a social system of ancien regime appear to be consubstantial. The analysis of the "holographic" and "homeostatic" constituants of the narrative (both concepts being borrowed from cybernetics) then mainly centres on the mirror effects and the evolution process of a very controlled. . .

Повний текст джерелаs functions. Function of a protein may be estimated from its sequence. Motifs or conserved subsequences are strong indicators of function. In a given sample set of protein sequences known to perform the same function, a certain subsequence or group of subsequences should be common
that is, occurrence (frequency) of common subsequences should be high. Our idea is to find the common subsequences through clustering and use these common groups (implicit motifs) to classify proteins. To calculate the distance between two subsequences, traditional string edit distance is modified so that only replacement is allowed and the cost of replacement is related to an amino acid substitution matrix. Based on the modified string edit distance, spectral clustering embeds the subsequences into some transformed space for which the clustering problem is expected to become easier to solve. For a given protein sequence, distribution of its subsequences over the clusters is the feature vector which is subsequently fed to a classifier. The most important aspect if this approach is the use of spectral clustering based on modified string edit distance.

Повний текст джерелаThe evolution of the aesthetic sense is a movement that has been engendered by a constant succession of innovations from 1905 to 1935. From cubism to surrealism, literary or poetical creations and productions have been observed, appreciated, contemplated and submitted to critical activity, revealing new techniques, news ways or devices, a new sensibility, which not only move away from classical aesthetics but actually break away from it. Common traits, new theories, a modernity which keeps being outdated, connect the avant-garde movements and are outlined in the uninterrupted sequence of three decades. Three main stages (1905-1914,1915-1924, 1925-1935) are defined which testity to this ineluctable evolution within the sphere of the avant-garde movements, the latest taking over the innovations of its predecessors, so that the base of the new aesthetics cannot exist but in a factual order, in an actual organic development. The aesthetic intention of each poet or writer is confirmed by the singularity of the work which fits into the continuous evolution of the avant-garde movements and stands out in a typology of the xxth century's aesthetics. Beauty reveals itself in surprising shapes since the aesthetic jugement is no longer based on taste but fully takes up the field of cognitive appreciation
Bu, Daher Julie. "Sequential Pattern Generalization for Mining Multi-source Data." Electronic Thesis or Diss., Université de Lorraine, 2020. http://www.theses.fr/2020LORR0204.
Повний текст джерелаHuge amounts of digital data have been created across years due to the increasing digitization in our everyday life. As a consequence, fast data collection and storage tools have been developed and data can be collected in huge volumes for various research and business purposes. The collected data can come from multiple data sources and can be of heterogeneous kinds thus forming heterogeneous multi-source datasets, and they can be analyzed to extract valuable information. Data mining is an important task in discovering interesting information from datasets. Different approaches in this domain have been proposed, among which pattern mining is the most important one. Pattern mining, including sequential pattern mining, discovers statistically relevant patterns (or sequential patterns) among data. The challenges of this domain include discovering important patterns with a limited complexity and by avoiding redundancy among the resulting patterns. Multi-source data could represent descriptive and sequential data, making the mining process complex. There could be problems of data similarity on one source level which leads to a limited number of extracted patterns. The aim of the thesis is to mine multi-source data to obtain valuable information and compensate the loss of patterns due to the problem of similarity with a limited complexity and by avoiding pattern redundancy. Many approaches have been proposed to mine multi-source data. These approaches either integrate multi-source data and perform a single mining process which increases the complexity and generates a redundant set of sequential patterns, or they mine sources separately and integrate the results which could lead to a loss of patterns. We propose G_SPM, a general sequential pattern mining algorithm that takes advantage of multi-source data to mine general patterns which compensates the loss of patterns caused by the problem of data similarity. These rich patterns contain various kinds of information and have higher data coverage than traditional patterns. G_SPM adopts a selective mining strategy of data sources where a main source is first mined, and other sources are mined only when similarity among patterns is detected, which limits the complexity and avoids pattern redundancy. The experimental results confirm that G_SPM succeeds in mining general patterns with a limited complexity.

Повний текст джерелаAll domains of science and technology produce large and heterogeneous data. Although a lot of work was done in this area, mining such data is still a challenge. No previous research work targets the mining of heterogeneous multidimensional sequential data. This thesis proposes a contribution to knowledge discovery in heterogeneous sequential data. We study three different research directions: (i) Extraction of sequential patterns, (ii) Classification and (iii) Clustering of sequential data. Firstly we generalize the notion of a multidimensional sequence by considering complex and heterogeneous sequential structure. We present a new approach called MMISP to extract sequential patterns from heterogeneous sequential data. MMISP generates a large number of sequential patterns as this is usually the case for pattern enumeration algorithms. To overcome this problem, we propose a novel way of considering heterogeneous multidimensional sequences by mapping them into pattern structures. We develop a framework for enumerating only patterns satisfying given constraints. The second research direction is in concern with the classification of heterogeneous multidimensional sequences. We use Formal Concept Analysis (FCA) as a classification method. We show interesting properties of concept lattices and of stability index to classify sequences into a concept lattice and to select some interesting groups of sequences. The third research direction in this thesis is in concern with the clustering of heterogeneous multidimensional sequential data. We focus on the notion of common subsequences to define similarity between a pair of sequences composed of a list of itemsets. We use this similarity measure to build a similarity matrix between sequences and to separate them in different groups. In this work, we present theoretical results and an efficient dynamic programming algorithm to count the number of common subsequences between two sequences without enumerating all subsequences. The system resulting from this research work was applied to analyze and mine patient healthcare trajectories in oncology. Data are taken from a medico-administrative database including all information about the hospitalizations of patients in Lorraine Region (France). The system allows to identify and characterize episodes of care for specific sets of patients. Results were discussed and validated with domain experts

Повний текст джерелаThe use in the legend of King Arthur of particuliar trees and herbs reflect a deliberat estetik choice, and shows a volonty of diegetic insertion which creates, from litterary's traditions and reality's suggestions, some typicals developpements. The fiction makes necessary a dynamic of fight at the tree which keeps links with the history ofmedieval acts ofwar and diplomacy. The identification ofthe "chivalry tree" is not left toéhance. The eviction of the oak tree and the selection of the pille tree narrative refers to a ï6manesc distribution of the tree's names. The arthurian's herbs are essentially mecine herbs. The gestures of the practitioner will be different whether the design is used to cure injuries, as an antidote or for para-pharmaceutical reasons. But the realism is limited to this specialisation of the gesture. Because the storyteller remains indifferent, except for the spices case, to the suggestions of time nomenclatures. The tale cultives principally the generic term erbes. The integration of the plant's life is also the subject of these works. The thematic of the gaste, which opens new horizons to all the Grail romances broadens the problematic of the "reverdie" beyond the suggestions of the topos of the seasonal revival inherited from the lyrical. The Queste deI Saint Graal goes back the threads of the story of the vegetative multiplication. With Gauvain and Galaad, the genealogical imagination adds itself to the question of the becoming of the saps

Повний текст джерелаTaking into account the semantic aspect of the textual data during the classification task has become a real challenge in the last ten years. This difficulty is in addition to the fact that most of the data available on social networks are short texts, which in particular results in making methods based on the "bag of words" representation inefficient. The approach proposed in this research project is different from the approaches proposed in previous work on the enrichment of short messages for three reasons. First, we do not use external knowledge like Wikipedia because typically short messages that are processed by the company come from specific domains. Secondly, the data to be processed are not used for the creation of resources because of the operation of the tool. Thirdly, to our knowledge there is no work on the one hand, which uses structured data such as the company's data to constitute semantic resources, and on the other hand, which measure the impact of enrichment on a system Interactive grouping of text flows. In this thesis, we propose the creation of resources enabling to enrich the short messages in order to improve the performance of the tool of the semantic grouping of the company Succeed Together. The tool implements supervised and unsupervised classification methods. To build these resources, we use sequential data mining techniques

Повний текст джерелаThe classification of biological data is one of the significant challenges inbioinformatics, as well for protein as for nucleic data. The presence of these data in hugemasses, their ambiguity and especially the high costs of the in vitro analysis in terms oftime and resources, make the use of data mining rather a necessity than a rational choice.However, the data mining techniques, which often process data under the relational format,are confronted with the inappropriate format of the biological data. Hence, an inevitablestep of pre-processing must be established.This thesis deals with the protein data preprocessing as a preparation step before theirclassification. We present motif extraction as a reliable way to address that task. The extractedmotifs are used as descriptors to encode proteins into feature vectors. This enablesthe use of known data mining classifiers which require this format. However, designing asuitable feature space, for a set of proteins, is not a trivial task.We deal with two kinds of protein data i:e:, sequences and tri-dimensional structures. In thefirst axis i:e:, protein sequences, we propose a novel encoding method that uses amino-acidsubstitution matrices to define similarity between motifs during the extraction step. Wedemonstrate the efficiency of such approach by comparing it with several encoding methods,using some classifiers. We also propose new metrics to study the robustness of some ofthese methods when perturbing the input data. These metrics allow to measure the abilityof the method to reveal any change occurring in the input data and also its ability to targetthe interesting motifs. The second axis is dedicated to 3D protein structures which are recentlyseen as graphs of amino acids. We make a brief survey on the most used graph-basedrepresentations and we propose a naïve method to help with the protein graph making. Weshow that some existing and widespread methods present remarkable weaknesses and do notreally reflect the real protein conformation. Besides, we are interested in discovering recurrentsub-structures in proteins which can give important functional and structural insights.We propose a novel algorithm to find spatial motifs from proteins. The extracted motifsmatch a well-defined shape which is proposed based on a biological basis. We compare withsequential motifs and spatial motifs of recent related works. For all our contributions, theoutcomes of the experiments confirm the efficiency of our proposed methods to representboth protein sequences and protein 3D structures in classification tasks.Software programs developed during this research work are available on my home page http://fc.isima.fr/~saidi

Повний текст джерелаThe tales "Beauty and Beast" and "The snake-prince" broadly circulated both in Europe and Asia take up the topic of the "animal fiancé cycle" which constitutes the main subject of this research. On one hand, the object of our research aims to study the theme of the "animal fiancé" through variant forms in the cultures of countries as different as France and China and on the other hand, to analyses the underlying symbolic structure. The protagonists, all single, seek the congenial soul in their initiatory quest. However, the common dream of a "fine marriage" is not only influenced but also imposed by the social institutions and traditions of each culture. This fantasy emerges as a personal desire but also as a bounder duty set by a community. How can we account for the condition of the hero who strives to become fully human or the heroine's plight? She proves curious, courageous, sympathetic, but doomed to endure a sting of hardships and punishments before becoming a "true wife". The hero and heroine face separate duties, functions and obstacles to overcome in their progress to initiation. Each achieves self-fulfilment in matrimony which entails destiny as well as social status. This study tries to understand more clearly this beautiful narrative belonging to oral tradition record, show its multiple forms, its transmission in time and space, and bring out its symbolic and sociological content
