Full textThe placenta is a temporary organ joins the mother and the fœtus, which transfers oxygen from the mother to the foetus, allows the evacuation of the carbon dioxide and the products of foetus metabolism. The goal of our work is to study the transfer function of placental development using ultrasound images. A new approach is developed during this work to classify the placental development by image processing techniques based on supervised neural network. The realized model by the wavelet transform based on MLP neural network, represents an effective tool answering our criteria and adapted to our applications concerning the study of placental maturation. The realized model application in the event of placental image processing opens interesting doors in terms of placental grades classification in order to identify the stages of maturation, authorizing the definition of a normal maturation and an abnormal maturation

Full textThe miniaturization of components in the micro-electronics industry involves the need of fast reliable technique of characterization with lower cost. Optical methods such as scatterometry are today promising alternative to this technological need. However, scatterometric method requires a certain number of hypothesis to ensure the resolution of an inverse problem, in particular the knowledge of the geometrical shape of the structure under test. The assumed model of the structure determines the quality of the characterization. In this thesis, we propose the use of neural networks as decision-making tools upstream of any characterization method. We validated the use of neural networks in the context of recognition of the geometrical shapes of the sample under testing by the use of optical signature in any scatterometric characterization process. First, the case of lithographic defect due to the presence of a resist residual layer at the bottom of the grooves is studied. Then, we carry out an analysis of model defect in the inverse problem resolution. Finally, we report results in the context of selection of geometric models by neural networks upstream of a classical scatterometric characterization process. This thesis has demonstrated that neural networks can well answer the problem of classification in ellipsometric scatterometry and their use can improve this optical characterization technique

Full textIn the same way as TV channels, data streams are represented as a sequence of successive events that can exhibit chronological relations (e.g. a series of programs, scenes, etc.). For a targeted channel, broadcast programming follows the rules defined by the channel itself, but can also be affected by the programming of competing ones. In such conditions, event sequences of parallel streams could provide additional knowledge about the events of a particular stream. In the sphere of machine learning, various methods that are suited for processing sequential data have been proposed. Long Short-Term Memory (LSTM) Recurrent Neural Networks have proven its worth in many applications dealing with this type of data. Nevertheless, these approaches are designed to handle only a single input sequence at a time. The main contribution of this thesis is about developing approaches that jointly process sequential data derived from multiple parallel streams. The application task of our work, carried out in collaboration with the computer science laboratory of Avignon (LIA) and the EDD company, seeks to predict the genre of a telecast. This prediction can be based on the histories of previous telecast genres in the same channel but also on those belonging to other parallel channels. We propose a telecast genre taxonomy adapted to such automatic processes as well as a dataset containing the parallel history sequences of 4 French TV channels. Two original methods are proposed in this work in order to take into account parallel stream sequences. The first one, namely the Parallel LSTM (PLSTM) architecture, is an extension of the LSTM model. PLSTM simultaneously processes each sequence in a separate recurrent layer and sums the outputs of each of these layers to produce the final output. The second approach, called MSE-SVM, takes advantage of both LSTM and Support Vector Machines (SVM) methods. Firstly, latent feature vectors are independently generated for each input stream, using the output event of the main one. These new representations are then merged and fed to an SVM algorithm. The PLSTM and MSE-SVM approaches proved their ability to integrate parallel sequences by outperforming, respectively, the LSTM and SVM models that only take into account the sequences of the main stream. The two proposed approaches take profit of the information contained in long sequences. However, they have difficulties to deal with short ones. Though MSE-SVM generally outperforms the PLSTM approach, the problem experienced with short sequences is more pronounced for MSE-SVM. Finally, we propose to extend this approach by feeding additional information related to each event in the input sequences (e.g. the weekday of a telecast). This extension, named AMSE-SVM, has a remarkably better behavior with short sequences without affecting the performance when processing long ones

Full textArtificial intelligence is a relatively recent research domain. With it, many breakthroughs were made on a number of problems that were considered very hard. Fine-grained classification is one of those problems. However, a relatively small amount of research has been done on this task even though itcould represent progress on a scientific, commercial and industrial level. In this work, we talk about applying fine-grained classification on concrete problems such as tree bark classification and mould classification in culture. We start by presenting fundamental deep learning concepts at the root of our solution. Then, we present multiple experiments made in order to try to solve the tree bark classification problem and we detail the novel dataset BarkNet 1.0 that we made for this project. With it, we were able to develop a method that obtains an accuracy of 93.88% on singlecrop in a single image, and an accuracy of 97.81% using a majority voting approach on all the images of a tree. We conclude by demonstrating the feasibility of applying our method on new problems by showing two concrete applications on which we tried our approach, industrial tree classification and mould classification.

Full textThis Ph.D focuses on the analysis of textual data in the health domain and in particular on the supervised multi-class classification of data from biomedical literature and social media.One of the major difficulties when exploring such data by supervised learning methods is to have a sufficient number of data sets for models training. Indeed, it is generally necessary to label manually the data before performing the learning step. The large size of the data sets makes this labellisation task very expensive, which should be reduced with semi-automatic systems.In this context, active learning, in which the Oracle intervenes to choose the best examples to label, is promising. The intuition is as follows: by choosing the smartly the examples and not randomly, the models should improve with less effort for the oracle and therefore at lower cost (i.e. with less annotated examples). In this PhD, we will evaluate different active learning approaches combined with recent deep learning models.In addition, when small annotated data set is available, one possibility of improvement is to artificially increase the data quantity during the training phase, by automatically creating new data from existing data. More precisely, we inject knowledge by taking into account the invariant properties of the data with respect to certain transformations. The augmented data can thus cover an unexplored input space, avoid overfitting and improve the generalization of the model. In this Ph.D, we will propose and evaluate a new approach for textual data augmentation.These two contributions will be evaluated on different textual datasets in the medical domain
