Multi-Source Domain Adaptation meets Dataset Distillation through Dataset Dictionary Learning

no code implementations14 Sep 2023 Eduardo Fernandes Montesuma, Fred Ngolè Mboula, Antoine Souloumiac

To solve it, we adapt previous works in the MSDA literature, such as Wasserstein Barycenter Transport and Dataset Dictionary Learning, as well as DD method Distribution Matching.

Multi-Source Domain Adaptation through Dataset Dictionary Learning in Wasserstein Space

1 code implementation27 Jul 2023 Eduardo Fernandes Montesuma, Fred Ngolè Mboula, Antoine Souloumiac

Based on our dictionary, we propose two novel methods for MSDA: DaDil-R, based on the reconstruction of labeled samples in the target domain, and DaDiL-E, based on the ensembling of classifiers learned on atom distributions.

Deep learning for ECoG brain-computer interface: end-to-end vs. hand-crafted features

no code implementations5 Oct 2022 Maciej Śliwowski, Matthieu Martin, Antoine Souloumiac, Pierre Blanchart, Tetiana Aksenova

The performance gap is reduced with bigger datasets, but considering the increased computational load, end-to-end training may not be profitable for this application.

Impact of dataset size and long-term ECoG-based BCI usage on deep learning decoders performance

no code implementations8 Sep 2022 Maciej Śliwowski, Matthieu Martin, Antoine Souloumiac, Pierre Blanchart, Tetiana Aksenova

In this study, we investigated the impact of long-term recordings on motor imagery decoding from two main perspectives: model requirements regarding dataset size and potential for patient adaptation.

Decoding ECoG signal into 3D hand translation using deep learning

no code implementations5 Oct 2021 Maciej Śliwowski, Matthieu Martin, Antoine Souloumiac, Pierre Blanchart, Tetiana Aksenova

These models have a limited representational capacity and may fail to capture the relationship between ECoG signal and continuous hand movements.

Streaming Binary Sketching based on Subspace Tracking and Diagonal Uniformization

no code implementations22 May 2017 Anne Morvan, Antoine Souloumiac, Cédric Gouy-Pailler, Jamal Atif

We demonstrate the quality of our binary sketches through experiments on real data for the nearest neighbors search task in the online setting.
