On factorization of rank-one auto-correlation matrix polynomials
Konstantin Usevich, Julien Flamant, Marianne Clausel +1
This article characterizes the rank-one factorization of auto-correlation matrix polynomials. We establish a sufficient and necessary uniqueness condition for uniqueness of the fac…
Coupled CP tensor decomposition with shared and distinct components for multi-task fMRI data fusion
Ricardo Augusto Borsoi, Isabell Lehmann, Mohammad Abu Baker Siddique Akhonda +4
Discovering components that are shared in multiple datasets, next to dataset-specific features, has great potential for studying the relationships between different subjects or tas…
Polarimetric phase retrieval: uniqueness and algorithms
Julien Flamant, Konstantin Usevich, Marianne Clausel +1
This work introduces a novel Fourier phase retrieval model, called polarimetric phase retrieval that enables a systematic use of polarization information in Fourier phase retrieval…
Tensor-based framework for training flexible neural networks
Yassine Zniyed, Konstantin Usevich, Sebastian Miron +1
Activation functions (AFs) are an important part of the design of neural networks (NNs), and their choice plays a predominant role in the performance of a NN. In this work, we are…
A general framework for constrained convex quaternion optimization
Julien Flamant, Sebastian Miron, David Brie
This paper introduces a general framework for solving constrained convex quaternion optimization problems in the quaternion domain. To soundly derive these new results, the propose…
Coupled Tensor Decomposition for Hyperspectral and Multispectral Image Fusion with Inter-Image Variability
Ricardo Augusto Borsoi, Clémence Prévost, Konstantin Usevich +3
Coupled tensor approximation has recently emerged as a promising approach for the fusion of hyperspectral and multispectral images, reconciling state of the art performance with st…
