Multivariate Temporal Dictionary Learning for EEG
Quentin Barthélemy, Cédric Gouy-Pailler, Yoann Isaac +3
This article addresses the issue of representing electroencephalographic (EEG) signals in an efficient way. While classical approaches use a fixed Gabor dictionary to analyze EEG s…
Multi-dimensional sparse structured signal approximation using split Bregman iterations
Yoann Isaac, Quentin Barthélemy, Jamal Atif +2
The paper focuses on the sparse approximation of signals using overcomplete representations, such that it preserves the (prior) structure of multi-dimensional signals. The underlyi…
Metrics for Multivariate Dictionaries
Sylvain Chevallier, Quentin Barthélemy, Jamal Atif
Overcomplete representations and dictionary learning algorithms kept attracting a growing interest in the machine learning community. This paper addresses the emerging problem of c…
