Full textIn oil and gas exploration and production, understanding subsurface geological structures, such as well logs and rock samples, is essential to provide predictive and decision support tools. Gathering and using data from a variety of sources, both structured and unstructured, such as relational databases and digitized reports on the subsurface geology, are critical. The main challenge for the structured data is the lack of a global schema to cross-reference all attributes from different sources. The challenges are different for unstructured data. Most subsurface geological reports are scanned versions of documents. Our dissertation aims to provide a structured representation of the different data sources and to build domain-specific language models for learning named entities related to subsurface geology

Full textDuring the past few years, an increasing interest for Machine Learning has been encountered, in various domains like image recognition or medical data analysis. However, a limitation of the classical PAC framework has recently been highlighted. It led to the emergence of a new research axis: Domain Adaptation (DA), in which learning data are considered as coming from a distribution (the source one) different from the one (the target one) from which are generated test data. The first theoretical works concluded that a good performance on the target domain can be obtained by minimizing in the same time the source error and a divergence term between the two distributions. Three main categories of approaches are derived from this idea : by reweighting, by reprojection and by self-labeling. In this thesis work, we propose two contributions. The first one is a reprojection approach based on boosting theory and designed for numerical data. It offers interesting theoretical guarantees and also seems able to obtain good generalization performances. Our second contribution consists first in a framework filling the gap of the lack of theoretical results for self-labeling methods by introducing necessary conditions ensuring the good behavior of this kind of algorithm. On the other hand, we propose in this framework a new approach, using the theory of (epsilon, gamma, tau)- good similarity functions to go around the limitations due to the use of kernel theory in the specific context of structured data

Full textTime series forecasting is a widely discussed issue for many years. Researchers from various disciplines have addressed it in several application areas : finance, medical, transportation, etc. In this thesis, we focused on machine learning methods : neural networks and SVM. We have also been interested in the meta-methods to push up the predictor performances, and more specifically the local models. In a divide and conquer strategy, the local models perform a clustering over the data sets before different predictors are affected into each obtained subset. We present in this thesis a new algorithm for recurrent neural networks to use them as local predictors. We also propose two novel clustering techniques suitable for local models. The first is based on Kohonen maps, and the second is based on binary trees
Hollocou, Alexandre. "Nouvelles approches pour le partitionnement de grands graphes." Thesis, Paris Sciences et Lettres (ComUE), 2018. http://www.theses.fr/2018PSLEE063.
Full textGraphs are ubiquitous in many fields of research ranging from sociology to biology. A graph is a very simple mathematical structure that consists of a set of elements, called nodes, connected to each other by edges. It is yet able to represent complex systems such as protein-protein interaction or scientific collaborations. Graph clustering is a central problem in the analysis of graphs whose objective is to identify dense groups of nodes that are sparsely connected to the rest of the graph. These groups of nodes, called clusters, are fundamental to an in-depth understanding of graph structures. There is no universal definition of what a good cluster is, and different approaches might be best suited for different applications. Whereas most of classic methods focus on finding node partitions, i.e. on coloring graph nodes so that each node has one and only one color, more elaborate approaches are often necessary to model the complex structure of real-life graphs and to address sophisticated applications. In particular, in many cases, we must consider that a given node can belong to more than one cluster. Besides, many real-world systems exhibit multi-scale structures and one much seek for hierarchies of clusters rather than flat clusterings. Furthermore, graphs often evolve over time and are too massive to be handled in one batch so that one must be able to process stream of edges. Finally, in many applications, processing entire graphs is irrelevant or expensive, and it can be more appropriate to recover local clusters in the neighborhood of nodes of interest rather than color all graph nodes. In this work, we study alternative approaches and design novel algorithms to tackle these different problems. The novel methods that we propose to address these different problems are mostly inspired by variants of modularity, a classic measure that accesses the quality of a node partition, and by random walks, stochastic processes whose properties are closely related to the graph structure. We provide analyses that give theoretical guarantees for the different proposed techniques, and endeavour to evaluate these algorithms on real-world datasets and use cases

Full textThis work concerns the use of temporal information on a sequence of more than two images for optical flow estimation. Optical flow is defined as the dense field (in any pixel) of the apparent movements in the image plane. We study on the one hand the use of a basis of temporal models, learned by principal component analysis from the studied data, to model the temporal dependence of the movement. This first study focuses on the context of particle image velocimetry in fluid mechanics. On the other hand, the new state of the art of optical flow estimation having recently been established by methods based on deep learning, we train convolutional neural networks to estimate optical flow by taking advantage of temporal continuity, in the case of natural image sequences. We then propose STaRFlow, a convolutional neural network exploiting a memory of information from the past by using a temporal recurrence. By repeated application of the same recurrent cell, the same learned parameters are used for the different time steps and for the different levels of a multiscale process. This architecture is lighter than competing networks while giving STaRFlow state-of-the-art performance. In the course of our work, we highlight several cases where the use of temporal information improves the quality of the estimation, in particular in the presence of occlusions, when the image quality is degraded (blur, noise), or in the case of thin objects

Full textThe human faculties of understanding are essentially multimodal. To understand the world around them, human beings fuse the information coming from all of their sensory receptors. Most of the documents used in automatic information processing contain multimodal information, for example text and image in textual documents or image and sound in video documents, however the processings used are most often monomodal. The aim of this thesis is to propose joint processes applying mainly to text and image for the processing of multimodal documents through two studies: one on multimodal fusion for the speaker role recognition in television broadcasts, the other on the complementarity of modalities for a task of linguistic analysis on corpora of images with captions. In the first part of this study, we interested in audiovisual documents analysis from news television channels. We propose an approach that uses in particular deep neural networks for representation and fusion of modalities. In the second part of this thesis, we are interested in approaches allowing to use several sources of multimodal information for a monomodal task of natural language processing in order to study their complementarity. We propose a complete system of correction of prepositional attachments using visual information, trained on a multimodal corpus of images with captions

Full textRefrigerated warehouses and cold rooms, mainly used for food conservation, constitute available storage cells; they can be considered as a network of "thermal batteries" ready to be used and one of the best existing solutions to store and delay electricity consumption. However, the risk related to temperature fluctuations of products due to periods of demand response - DR* and the risk of energy overconsumption limit the use of this strategy by industrials in food refrigeration. The present PhD thesis aims to characterize the electrical DR of warehouses and cold rooms by examining the thermal behavior of those systems, in terms of temperature fluctuation and electrical consumption. An experimental set-up was developed to study several DR scenarios (duration, frequency and operating conditions) and to propose new indicators to characterize the impact of DR periods on the thermal and energy behavior of refrigeration systems. This study has highlighted the importance of the presence of load to limit the temperature rise and thus to reduce the impact on stored products. The potential for DR application in the case of a cold store and a cold room was assessed, based on the development of two modeling approaches: “black box” (Machine Learning by artificial neural networks using Deep Learning models) and “white box” (physics). A possibility of interaction between these two approaches has been proposed, based on the use of black box models for prediction and the use of the white box model to generate input and output data

Full textThis thesis has for objective to propose new methods allowing the study of the evolution of the metabolism. For that purpose, we chose to deal with the problem of comparison of the metabolism of hundred microorganisms.To compare the metabolism of various species, it is necessary to know at first the metabolism of each of these species.We work with proteomes of the microorganisms coming from various databases and sequenced and annotated by various teams, via various methods. The functional annotation can thus be of heterogeneous quality. That is why it is necessary to make a standardized functional annotation of this proteomes.The annotation of protein sequences can be realized by the transfer of annotations between orthologs sequences. There are more than 39 databases listing orthologues predicted by various methods. It is known that these methods lead to partially different predictions. To take into account current predictions and also adding relevant information, we developed the meta approach MARIO. This one combines the intersections of the results of several methods of detection of groups of orthologs and add sequences to this groups by using HMM profiles. We show that our meta approach allows to predict a largest number of orthologs while improving the similarity of function of the pairs of predicted orthologs. It allowed us to predict the enzymatic directory of 178 proteomes of microorganisms (among which 174 fungi).Secondly, we analyze these enzymatic directories in order to analyse the evolution of the metabolism. In this purpose, we look for combinations of presence / absence of enzymatic activities allowing to characterize a taxonomic group. So, it becomes possible to deduct if the creation of a particular taxonomic group can give some explanation by (or led to) the appearance of specificities at the level of its metabolism.For that purpose, we applied interpretable machine learning methods (rulers and decision trees) to the enzymatic profiles. We use as attributes the enzymatic activities, as classes the taxonomic groups and as examples the fungi. The results, coherent with our current knowledge on these species, show that the application of methods of machine learning is effective to extract informations of the phylogenetic profiles. The metabolism thus keeps tracks of the evolution of the species.Furthermore, this approach, in the case of prediction of classifiers presenting a low number of errors, can allow to highlight the existence of likely horizontal transfers. It is the case for example of the transfer of the gene coding for the EC:3.1.6.6 of an ancestor of pezizomycotina towards an ancestor of Ustilago maydis
