Full textNombre de problèmes issus du traitement de signal peuvent être modélisés par des équations/problèmes tensoriels. La spécificité des problèmes de traitement de signal est qu’ils donnent lieu à des décompositions tensorielles structurées. L’objectif principal de cette thèse est, d’une part, le développement de méthodes numériques appliquées aux problèmes de décompositions de tenseurs structurés et, d’autre part, leur application en traitement de signal. Dans un premier temps, nous proposons des méthodes pour le calcul de la décomposition CANDECOMP/PARAFAC (CP) avec un facteur matriciel semi-unitaire. De plus, nous développons des méthodes pour résoudre des problèmes d’analyse en composantes indépendantes (ICA) pouvant être modélisés par une décomposition CP structurée, en les considérant comme des problèmes de décompositions CP sous contrainte de semi-unitarité. Ensuite, pour le calcul de décompositions CP avec symétries hermitiennes partielles, nous proposons des méthodes de décompositions simultanées de Schur généralisées. D’un point de vue numérique, nous développons le calcul de décompositions CP réelles par une méthode de Jacobi. En troisième lieu, nous nous attaquons à la décomposition de tenseurs ayant des facteurs matriciels bande ou Hankel/Toeplitz, conjointement (ou non) à des symétries hermitiennes partielles. Ces méthodes sont appliquées à la résolution de problèmes d’identification aveugle basés sur des cumulants. Enfin, nous proposons une méthode (plus) efficace pour l’égalisation aveugle de canaux paraunitaires basée sur les itérations de Jacobi. Dans le même esprit, nous dérivons une solution algébrique à la méthode de Jacobi pour effectuer la diagonalisation conjointe de matrices réelles définies positives

Full textLow rank tensor decomposition has been playing for the last years an important rolein many applications such as blind source separation, telecommunications, sensor array processing,neuroscience, chemometrics, and data mining. The Canonical Polyadic tensor decomposition is veryattractive when compared to standard matrix-based tools, manly on system identification. In this thesis,we propose: (i) several algorithms to compute specific low rank-approximations: finite/iterativerank-1 approximations, iterative deflation approximations, and orthogonal tensor decompositions. (ii)A new strategy to solve multivariate quadratic systems, where this problem is reduced to a best rank-1 tensor approximation problem. (iii) Theoretical results to study and proof the performance or theconvergence of some algorithms. All performances are supported by numerical experiments

Full textA wide class of nonconvex optimization problem is represented by rational optimization problems. The latter appear naturally in many areas such as signal processing or chemical engineering. However, finding the global optima of such problems is intricate. A recent approach called Lasserre's hierarchy provides a sequence of convex problems that has the theoretical guarantee to converge to the global optima. Nevertheless, this approach is computationally challenging due to the high dimensions of the convex relaxations. In this thesis, we tackle this challenge for various signal processing problems.First, we formulate the reconstruction of sparse signals as a rational optimization problem. We show that the latter has a structure that we wan exploit in order to reduce the complexity of the associated relaxations. We thus solve several practical problems such as the reconstruction of chromatography signals. We also extend our method to the reconstruction of various types of signal corrupted by different noise models.In a second part, we study the convex relaxations generated by our problems which take the form of high-dimensional semi-definite programming problems. We consider several algorithms mainly based on proximal operators to solve those high-dimensional problems efficiently.The last part of this thesis is dedicated to the link between polynomial optimization and symmetric tensor decomposition. Indeed, they both can be seen as an instance of the moment problem. We thereby propose a detection method as well as a decomposition algorithm for symmetric tensors based on the tools used in polynomial optimization. In parallel, we suggest a robust extraction method for polynomial optimization based on tensor decomposition algorithms. Those methods are illustrated on signal processing problems

Full textLast decades, tensor decompositions have gained in popularity in several application domains. Most of the existing tensor decomposition methods require an estimating of the tensor rank in a preprocessing step to guarantee an outstanding decomposition results. Unfortunately, learning the exact rank of the tensor can be difficult in some particular cases, such as for low signal to noise ratio values. The objective of this thesis is to compute the best low-rank tensor approximation by a joint estimation of the rank and the loading matrices from the noisy tensor. Based on the low-rank property and an over estimation of the loading matrices or the core tensor, this joint estimation problem is solved by promoting group sparsity of over-estimated loading matrices and/or the core tensor. More particularly, three new methods are proposed to achieve efficient low rank estimation for three different tensors decomposition models, namely Canonical Polyadic Decomposition (CPD), Block Term Decomposition (BTD) and Multilinear Tensor Decomposition (MTD). All the proposed methods consist of two steps: the first step is designed to estimate the rank, and the second step uses the estimated rank to compute accurately the loading matrices. Numerical simulations with noisy tensor and results on real data the show effectiveness of the proposed methods compared to the state-of-the-art methods

Full textThis thesis introduces new joint eigenvalue decomposition algorithms. These algorithms allowamongst others to solve the canonical polyadic decomposition problem. This decomposition iswidely used for blind source separation. Using the joint eigenvalue decomposition to solve thecanonical polyadic decomposition problem allows to avoid some problems whose the others canonicalpolyadic decomposition algorithms generally suffer, such as the convergence rate, theoverfactoring sensibility and the correlated factors sensibility. The joint eigenvalue decompositionalgorithms dealing with complex data give either good results when the noise power is low, orthey are robust to the noise power but have a high numerical cost. Therefore, we first proposealgorithms equally dealing with real and complex. Moreover, in some applications, factor matricesof the canonical polyadic decomposition contain only nonnegative values. Taking this constraintinto account makes the algorithms more robust to the overfactoring and to the correlated factors.Therefore, we also offer joint eigenvalue decomposition algorithms taking advantage of thisnonnegativity constraint. Suggested numerical simulations show that the first developed algorithmsimprove the estimation accuracy and reduce the numerical cost in the case of complexdata. Our numerical simulations also highlight the fact that our nonnegative joint eigenvaluedecomposition algorithms improve the factor matrices estimation when their columns have ahigh correlation degree. Eventually, we successfully applied our algorithms to two blind sourceseparation problems : one concerning numerical telecommunications and the other concerningfluorescence spectroscopy

Full textMultidimensional data sets and signals occupy an important place in recent application fields. Tensor decomposition represents a powerful mathematical tool for modeling multidimensional data and signals, without losing the interdimensional relations. The Canonical Polyadic (CP) model, a widely used tensor decomposition model, is unique up to scale and permutation indeterminacies. This property facilitates the physical interpretation, which has led the integration of the CP model in various contexts. The main challenge facing the tensor modeling is the computational complexity and memory requirements. High-order tensors represent a important issue, since the computational complexity and the required memory space increase exponentially with respect to the order. Another issue is the size of the tensor in the case of large-scale problems, which adds another burden to the complexity and memory. Tensor Networks (TN) theory is a promising framework, allowing to reduce high-order problems into a set of lower order problems. In particular, the Tensor-Train (TT) model, one of the TN models, is an interesting ground for dimensionality reduction. However, respresenting a CP tensor using a TT model, is extremely expensive in the case of large-scale tensors, since it requires full matricization of the tensor, which may exceed the memory capacity.In this thesis, we study the dimensionality reduction in the context of sparse-coding and high-order coupled tensor decomposition. Based on the results of Joint dImensionality Reduction And Factor rEtrieval (JIRAFE) scheme, we use the flexibility of the TT model to integrate the physical driven constraints and the prior knowledge on the factors, with the aim to reduce the computation time. For large-scale problems, we propose a scheme allowing to parallelize and randomize the different steps, i.e., the dimensionality reduction and the factor estimation. We also propose a grid-based strategy, allowing a full parallel processing for the case of very large scales and dynamic tensor decomposition

Full textThe existence of the dark matter and the truth beyond its nature has been one of the greatest puzzles of the twentieth century and still it is nowadays. In the last decades several hypotheses, such as the WIMPs model, have been proposed to solve such puzzle but none of them has been able so far to succeed.In this thesis work we will focus on another very appealing model in which dark matter is successfully described by an ultra-light scalar field whose origin can be sought in the low-energy limit of one of the most promising unification theories: the String Theory.In this work we show how such scalar field, if present, interacts with standard matter and in particular with the optical apparatus that is at the core of gravitational waves antennas. We derive and discuss the signal produced by this interaction through different approaches deriving both approximated and exact solutions. Special attention is paid to the second-order term of the signal approximate series expansion whose contribution ends up to be not negligible when one factors in the specific geometrical dimensions and frequency range of gravitational waves detectors like Advanced LIGO and Advanced Virgo.A suggested by recent surveys we assume presence of a dark matter stream in the local neighborhood of the solar system and show its effect on the signal.We then propose and discuss a hierarchical statistical analysis aimed to the signal detection. In case of no detection a limit curve for the coupling parameter dg* is derived. Such curve is then analyzed in detail showing the magnitude of the contribution of the first-order and second-order terms of the signal series expansion. We analyze the modification of the constraint curve due to the variation of the fraction of local dark matter belonging to the stream. We show finally how the constraint curve responds to variations of the search parameter and discuss the optimal choices
