A review of center of pressure (COP) variables to quantify standing balance in elderly people: Algorithms and open-access code

Postural control is often quantified by recording the trajectory of the center of pressure (COP)-also called stabilogram-during human quiet standing. This quantification has many important applications, such as the early detection of balance…

Implicit consensus clustering from multiple graphs

Dealing with relational learning generally relies on tools modeling relational data. An undirected graph can represent these data with vertices depicting entities and edges describing the relationships between the entities. These relationships can…

Tensor Convolutional Dictionary Learning with CP Low-Rank activations

In this paper, we propose an extension of the standard CDL problem with tensor representation, where each activation is constrained to be "low-rank" through a Canonical Polyadic decomposition. We show that this important additional constraint…

Fast Approximation of the Sliced-Wasserstein Distance Using Concentration of Random Projections

The Sliced-Wasserstein distance (SW) is being increasingly used in machine learning applications as an alternative to the Wasserstein distance and offers significant computational and statistical benefits. Since it is defined as an expectation over…

Learning spatial filters from EEG signals with Graph Signal Processing methods

In this paper, we propose to learn a spatial filter directly from Electroencephalography (EEG) signals using graph signal processing tools. We combine a graph learning algorithm with a high-pass graph filter to remove spatially large signals from…

Conséquences développementales de la maltraitance infantile : de la résilience à la psychopathologie. Exemple du trouble de personnalité borderline à l'adolescence

La maltraitance infantile (MI) a des conséquences nombreuses et durables sur le développement des enfants et des adolescents allant de la résilience à la psychopathologie. L'objectif de cette thèse est d'étudier différentes hypothèses pouvant sous…

Late-onset and nonlate-onset schizophrenia: A comparison of clinical characteristics in a multicenter study

Objectives Data are scarce regarding the potential clinical differences between non-late onset schizophrenia (NLOS, i.e., disorder occurring before 40 years of age), late-onset schizophrenia (LOS, occurring between ages 40 and 60 years) and very…

A Review on Contrastive Learning Methods and Applications to Roof-Type Classification on Aerial Images

Unsupervised learning based on Contrastive Learning (CL) has attracted a lot of interest recently. This is due to excellent results on a variety of subsequent tasks (especially classification) on benchmark datasets (ImageNet, CIFAR-10, etc.) without…
