Merckling, Astrid. "Unsupervised pretraining of state representations in a rewardless environment." Electronic Thesis or Diss., Sorbonne université, 2021. http://www.theses.fr/2021SORUS141.
Full textThis thesis seeks to extend the capabilities of state representation learning (SRL) to help scale deep reinforcement learning (DRL) algorithms to continuous control tasks with high-dimensional sensory observations (such as images). SRL allows to improve the performance of DRL by providing it with better inputs than the input embeddings learned from scratch with end-to-end strategies. Specifically, this thesis addresses the problem of performing state estimation in the manner of deep unsupervised pretraining of state representations without reward. These representations must verify certain properties to allow for the correct application of bootstrapping and other decision making mechanisms common to supervised learning, such as being low-dimensional and guaranteeing the local consistency and topology (or connectivity) of the environment, which we will seek to achieve through the models pretrained with the two SRL algorithms proposed in this thesis

Full textThe dictionary learning problem has received increasing attention for the last ten years. DL is an adaptive approach for sparse data representation. Many state-of-the-art DL methods provide good performances for problems such as approximation, denoising and inverse problems. However, their numerical complexity restricts their use to small image patches. Thus, dictionary learning does not capture large features and is not a viable option for many applications handling large images, such as those encountered in remote sensing. In this thesis, we propose and study a new model for dictionary learning, combining convolutional sparse coding and dictionaries defined by convolutional tree structures. The aim of this model is to provide efficient algorithms for large images, avoiding the decomposition of these images into patches. In the first part, we study the optimization of a composition of convolutions with sparse kernels, to reach a target atom (such as a cosine, wavelet or curvelet). This is a non-convex matrix factorization problem. We propose a resolution method based on a Gaus-Seidel scheme, which produces good approximations of target atoms and whose complexity is linear with respect to the image size. Moreover, numerical experiments show that it is possible to find a global minimum. In the second part, we introduce a dictionary structure based on convolutional trees. We propose a dictionary update algorithm adapted to this structure and which complexity remains linear with respect to the image size. Finally, a sparse coding step is added to the algorithm in the last part. For each evolution of the proposed method, we illustrate its approximation abilities with numerical experiments

Full textThis study deals with the localization of a source which emits an unknown signal in a propagation medium thanks to a scattering model. In this model, the advection parameters are supposed to be known, but the diffusion ones are unknown and hard to measure. The source signal distorted by the propagation is provided by a set of spatially distributed sensors. These observations are disturbed by Gaussian iid noises. We show for some kind of model, the possibility to obtain a discrete state-space model using the finite differences, where the evolution matrix A describes the propagation. Some of the matrix A parameters needs to be identified. In the same way, the matrix B that characterizes the source placement is completely unknown. The matrix C describes the sensor array architecture. Each source-sensor channel is approximated by an unknown FIR filter. The blind identification consists in estimating  conditionnally to a source position. The subspace method, based on the decomposition in signal and noise subspaces, leads to the identification of the impulse responses of the channels. The localization is the reduced to an iterative process of blind identification and decision in order to maximize a localization criterion. A few temporal and frequential criterions have been developed. This approach depends on the size of the potential source positions set, but an initial localization method allows a size reduction of this set by means of observations crosscorrelations and numerical propagation scheme. The use of a propagation model in a real case of atmospheric pollution where the wind parameters are variable but known, leads to study the non stationary blind identification problem. We show that the difficulty is reduced to the search of a consistent estimator of the autocorrelation matrix

Full text[The works presented in this thesis concern the Internal Model Control (I. M. C. ). The first part presents the main properties of this structure which combines the advantages of open-loop scheme (the controller is an approximate inverse of the model) and closed-loop structure (ability to cope with modelling errors and unmeasured disturbances). A comparison with the conventional closed-loop is briefly presented. In the second part, an asymptotic precision criterion is introduced; The conditions that are to be verified by the blocks of the I. M. C. , for zeroing the asymptotic error between the output and a polynomial input, are settled down. The controller is interpreted as an approximate inverse of the model. In discrete time, the use of F. I. R. (Finite Impulse Response) forms permits the synthesis of a stable and realisable controller. The third part deals with the problem of the model inversion in discrete time and in state space. It allows us to consider some vary linear or non-linear models, which are linear versus the control variable. The controller is decomposed in two parts: the first one generates the control variable in terms of model state and the reference objective, the second one generates the prediction of the reference signal. Asymptotic accuracy is guaranteed for reference inputs that are polynomial, with a given order, versus time. The last part presents the synthesis of an I. M. C. Based on the use of the above controller. The robustness filter becomes a predictor of the error between plant and model outputs, the dynamic of which is tuned according to the knowledge of the plant-model mismatch. Two approaches have been proposed to built in this filter. The first one uses the same technique as for the reference predictor. In the other, the usual notion of filtering is replaced by a measure of the prediction quality. ]

Full textIn this thesis, we study how representation learning methods can be applied to user-generated data. Our contributions cover three different applications but share a common denominator: the extraction of relevant user representations. Our first application is the item recommendation task, where recommender systems build user and item profiles out of past ratings reflecting user preferences and item characteristics. Nowadays, textual information is often together with ratings available and we propose to use it to enrich the profiles extracted from the ratings. Our hope is to extract from the textual content shared opinions and preferences. The models we propose provide another opportunity: predicting the text a user would write on an item. Our second application is sentiment analysis and, in particular, polarity classification. Our idea is that recommender systems can be used for such a task. Recommender systems and traditional polarity classifiers operate on different time scales. We propose two hybridizations of these models: the former has better classification performance, the latter highlights a vocabulary of surprise in the texts of the reviews. The third and final application we consider is urban mobility. It takes place beyond the frontiers of the Internet, in the physical world. Using authentication logs of the subway users, logging the time and station at which users take the subway, we show that it is possible to extract robust temporal profiles

Full textThe crisis of management instrumentation wich appeared in the 80's can be interpreted as a crisis of the representation modes of organization. Therfore this thesis offers some thoughts on the type of organization aimed at controlling, starting from a model based an activities. First, we use graphical representations in order to model the activities of organisations in applied cases. Our analysis identifies some limits the functional tools which are most frequently used. We then suggest some solutions by resorting to a cognitive representation of the activities. Secondly, we develop a typology which structures the diversity of the processes. We distinguish three categories : the structured process, the semi-structured process, the non structured process. Those configurations can in particular be differentiated by their strategies of environmental adaptation and their structure of management. The objective to provide a language so as to facilitate the diagnosis on the functioning of the processes. Our study resulted in devising a dashboard intended to drive the collective mechanisms of adaptation and knowledge creation. Our analysis emphasises both the parameters of control of these mechanisms and the impact of those parameters on the dynamic of the learning processes. Finally, managing the processes appears to be a way to mobilise the cognitive attention of the actors of the organisation. The point is especially important when the operators have to solve radically new problems of strategic importance for the organisation and thus need to explore new. Fields of knowledge. Conversely, managing the processes helps to save the cognitive resources of the organisation in situations where the members have to solve well-defined and well-known problems by exploiting available and explicit knowledge
