Full textThis research focuses on the under-representation of women in Haitian politics. More specifically, it seeks to understand this under-representation from the lived experiences and perspectives of women who have reached political decision-making positions in the country. Using a theoretical framework that mobilizes the concepts of “gender consciousness” and “women political representation” developed by Manon Tremblay (1996), the thesis offers a comprehensive analysis of this social phenomenon. A series of semi-structured interviews was carried out with seven Haitian elected officials, including two senators and five former ministers for the Status of Women and Women's Rights. The results of the analysis show that gender-differential socialization, gender stereotypes and gender-based violence can explain the low representation of Haitian women in political decision-making positions. In addition, the analysis highlights the link between the gender consciousness of elected officials and the political representation of women in Haiti. The analysis reveals that the respondents have a gender consciousness and are aware of the gender inequalities that exist in the Haitian society in general and within the political class in particular. On the other hand, several elected officials do not consider themselves as feminists and say that they have represented the population as a whole (men and women) and not the specific interests of women. Conversely, analysis shows that some elected officials are not only gender conscious, but that they have brought the demands of Haitian women into the political arena. While in power, the actions they took addressed the causes of the under-representation of women in politics and the obstacles they had experienced themselves.
Flocon-Cholet, Joachim. "Classification audio sous contrainte de faible latence." Thesis, Rennes 1, 2016. http://www.theses.fr/2016REN1S030/document.
Full textThis thesis focuses on audio classification under low-latency constraints. Audio classification has been widely studied for the past few years, however, a large majority of the existing work presents classification systems that are not subject to temporal constraints : the audio signal can be scanned freely in order to gather the needed information to perform the decision (in that case, we may refer to an offline classification). Here, we consider audio classification in the telecommunication domain. The working conditions are now more severe : algorithms work in real time and the analysis and processing steps are now operated on the fly, as long as the signal is transmitted. Hence, the audio classification step has to meet the real time constraints, which can modify its behaviour in different ways : only the current and the past observations of the signal are available, and, despite this fact the classification system has to remain reliable and reactive. Thus, the first question that occurs is : what strategy for the classification can we adopt in order to tackle the real time constraints ? In the literature, we can find two main approaches : the frame-level classification and the segment-level classification. In the frame-level classification, the decision is performed using only the information extracted from the current audio frame. In the segment-level classification, we exploit a short-term information using data computed from the current and few past frames. The data fusion here is obtained using the process of temporal feature integration which consists of deriving relevant information based on the temporal evolution of the audio features. Based on that, there are several questions that need to be answered. What are the limits of these two classification framework ? Can an frame-level classification and a segment-level be used efficiently for any classification task ? Is it possible to obtain good performance with these approaches ? Which classification framework may lead to the best trade-off between accuracy and reactivity ? Furthermore, for the segment-level classification framework, the temporal feature integration process is mainly based on statistical models, but would it be possible to propose other methods ? Throughout this thesis, we investigate this subject by working on several concrete case studies. First, we contribute to the development of a novel audio algorithm dedicated to audio protection. The purpose of this algorithm is to detect and suppress very quickly potentially dangerous sounds for the listener. Our method, which relies on the proposition of three features, shows high detection rate and low false alarm rate in many use cases. Then, we focus on the temporal feature integration in a low-latency framework. To that end, we propose and evaluate several methodologies for the use temporal integration that lead to a good compromise between performance and reactivity. Finally, we propose a novel approach that exploits the temporal evolution of the features. This approach is based on the use of symbolic representation that can capture the temporal structure of the features. The idea is thus to find temporal patterns that are specific to each audio classes. The experiments performed with this approach show promising results

Full textThis thesis focuses on the distributed source localization problem. In a first step, performance of high resolution methods in the presence of model errors due to the angular distribution of source has been studied. Theoretical expressions of the estimation bias and the mean square error of the direction of arrival of sources have been established in terms of model error. The impacts of the array geometry on the performances have studied in order to optimize the robustness of the array to the model error due to distributed sources.Theoretical results have been validated by numerical simulations.In a second step, a new approach for the localization of spatially distributed source has been proposed: the approach is based on the sparsity and low-rank property of the spatial covariance matrix of the sources. The proposed method provides also an estimation of the distribution shapes of the sources. Simulation results exhibit the advantages of exploiting the sparsity and the low rank properties

Full textIn the present document we treat three different topics related to stochastic optimal control and stochastic calculus, pivoting on thenotion of backward stochastic differential equation (BSDE) driven by a random measure.After a general introduction, the three first chapters of the thesis deal with optimal control for different classes of non-diffusiveMarkov processes, in finite or infinite horizon. In each case, the value function, which is the unique solution to anintegro-differential Hamilton-Jacobi-Bellman (HJB) equation, is probabilistically represented as the unique solution of asuitable BSDE. In the first chapter we control a class of semi-Markov processes on finite horizon; the second chapter isdevoted to the optimal control of pure jump Markov processes, while in the third chapter we consider the case of controlled piecewisedeterministic Markov processes (PDMPs) on infinite horizon. In the second and third chapters the HJB equations associatedto the optimal control problems are fully nonlinear. Those situations arise when the laws of the controlled processes arenot absolutely continuous with respect to the law of a given, uncontrolled, process. Since the corresponding HJB equationsare fully nonlinear, they cannot be represented by classical BSDEs. In these cases we have obtained nonlinear Feynman-Kacrepresentation formulae by generalizing the control randomization method introduced in Kharroubi and Pham (2015)for classical diffusions. This approach allows us to relate the value function with a BSDE driven by a random measure,whose solution hasa sign constraint on one of its components.Moreover, the value function of the original non-dominated control problem turns out to coincide withthe value function of an auxiliary dominated control problem, expressed in terms of equivalent changes of probability measures.In the fourth chapter we study a backward stochastic differential equation on finite horizon driven by an integer-valued randommeasure $mu$ on $R_+times E$, where $E$ is a Lusin space, with compensator $nu(dt,dx)=dA_t,phi_t(dx)$. The generator of thisequation satisfies a uniform Lipschitz condition with respect to the unknown processes.In the literature, well-posedness results for BSDEs in this general setting have only been established when$A$ is continuous or deterministic. We provide an existence and uniqueness theorem for the general case, i.e.when $A$ is a right-continuous nondecreasing predictable process. Those results are relevant, for example,in the frameworkof control problems related to PDMPs. Indeed, when $mu$ is the jump measure of a PDMP on a bounded domain, then $A$ is predictable and discontinuous.Finally, in the two last chapters of the thesis we deal with stochastic calculus for general discontinuous processes.In the fifth chapter we systematically develop stochastic calculus via regularization in the case of jump processes,and we carry on the investigations of the so-called weak Dirichlet processes in the discontinuous case.Such a process $X$ is the sum of a local martingale and an adapted process $A$ such that $[N,A] = 0$, for any continuouslocal martingale $N$.Given a function $u:[0,T] times R rightarrow R$, which is of class $C^{0,1}$ (or sometimes less), we provide a chain rule typeexpansion for $u(t,X_t)$, which constitutes a generalization of It^o's lemma being valid when $u$ is of class $C^{1,2}$.This calculus is applied in the sixth chapter to the theory of BSDEs driven by random measures.In several situations, when the underlying forward process $X$ is a special semimartingale, or, even more generally,a special weak Dirichlet process,we identify the solutions $(Y,Z,U)$ of the considered BSDEs via the process $X$ and the solution $u$ to an associatedintegro PDE

Full textIn this monograph, we study the exact ℓ₀ based sparse representation problem. For the classical dictionary learning problem, the solution is obtained by iteratively processing two steps: sparse coding and dictionary updating. However, even the problem associated with sparse coding is non-convex and NP-hard. The method for solving this is to reformulate the problem as mixed integer quadratic programming (MIQP). Then by introducing two optimization techniques, initialization by proximal method and relaxation with augmented contraints, the algorithmis greatly speed up (which is thus called AcMIQP) and applied in image denoising, which shows the good performance. Moreover, the classical problem is extended to learn an incoherent dictionary. For dealing with this problem, AcMIQP or proximal method is used for sparse coding. As for dictionary updating, augmented Lagrangian method (ADMM) and extended proximal alternating linearized minimizing method are combined. This exact ℓ₀ based incoherent dictionary learning is applied in image recovery, which illustrates the improved performance with a lower coherence
Carreno, Medrano Pamela. "Analyse et synthèse de mouvements théâtraux expressifs." Thesis, Lorient, 2016. http://www.theses.fr/2016LORIS424/document.
Full textThis thesis addresses the analysis and generation of expressive movements for virtual human characters. Based on previous results from three different research areas (perception of emotions and biological motion, automatic recognition of affect and computer character animation), a low-dimensional motion representation is proposed. This representation consists of the spatio-temporal trajectories of end-effectors (i.e., head, hands and feet) and pelvis. We have argued that this representation is both suitable and sufficient for characterizing the underlying expressive content in human motion and for controlling the generation of expressive whole-body movements. In order to prove these claims, this thesis proposes: i.) A new motion capture database inspired by physical theater theory. This database contains examples from different motion classes (i.e., periodic movements, functional behaviors, spontaneous motions, and theater-inspired motion sequences) and distinct emotional states (happiness, sadness, relaxedness, stress and neutral) performed by several actors. ii.) A user study and automatic classification framework de- signed to qualitatively and quantitatively assess the amount of emotion-related information conveyed and encoded in the proposed representation. We have observed that although slight differences in performance were found with respect to the cases in which the entire body was used, our proposed representation preserves most of the motion cues salient to the expression of affect and emotions. iii.) A simple motion synthesis system able to capable of: a) reconstructing whole-body movements from the proposed low-dimensional representation, and b) producing novel end- effector (and pelvis) expressive trajectories. A quantitative and qualitative evaluation of the generated whole body motions shows that these motions are as expressive as the movements recorded from human actors
Lu, Yi. "Calcul fonctionnel non-anticipatif et applications aux processus stochastiques." Thesis, Paris 6, 2017. http://www.theses.fr/2017PA066418/document.
Full textThis thesis focuses on various mathematical questions arising in the non-anticipative functional calculus, which is based on a notion of pathwise directional derivatives for functionals. We extend the scope and results of this calculus to functionals which may not admit such derivatives, either through approximations (Part I) or by defining a notion of weak vertical derivative (Part II). In the first part, we consider the representation of conditional expectations as non-anticipative functionals. We show that it is possible under very general conditions to approximate such functionals by a sequence of smooth functionals in an appropriate sense. This approach provides a systematic method for computing explicit approximations to martingale representations for a large class of Brownian functionals. We also derive explicit convergence rates of the approximations. These results are then applied to the problem of sensitivity analysis and dynamic hedging of (path-dependent) contingent claims. In the second part, we propose a concept of weak vertical derivative for non-anticipative functionals which may fail to possess directional derivatives. The definition of the weak vertical derivative is based on the notion of pathwise quadratic variation and makes use of the duality associated to the associated bilinear form. We show that the notion of weak vertical derivative leads to a functional characterization of local martingales with respect to a reference process, and allows to define a concept of pathwise weak solution for path-dependent partial differential equations
