A Closed-Form Unsupervised Geometry-Aware Dimensionality Reduction Method in the Riemannian Manifold of SPD Matrices

Congedo, M., Rodrigues, P., Bouchard, F., Barachant, A., Jutten, C.
39th International Conference of the IEEE Engineering in Medicine and Biology Society, pp.3198-3201, 2017

Riemannian geometry has been found accurate and robust for classifying multidimensional data, for instance, in brain-computer interfaces based on electroencephalography. Given a number of data points on...

Single-trial detection of event-related fields in MEG from the presentation of happy faces: Results of the Biomag 2016 data challenge

H. Cecotti, A. Barachant, J.R. King, J. Sanchez Bornot, G. Prasad
39th International Conference of the IEEE Engineering in Medicine and Biology Society, pp.4467-4470, 2017

The recognition of brain evoked responses at the single-trial level is a challenging task. Typical non-invasive brain-computer interfaces based on event-related brain responses use eletroencephalograhy. In this study, we consider...

Brain Invaders 2 : an open source Plug & Play multi-user BCI videogame

Korczowski, L., Barachant A., Andreev A., Jutten C., Congedo M.
6th International Brain-Computer Interface Meeting (BCI Meeting 2016), 2016

In 2011 we proposed Brain Invaders , a BCI videogame inspired from the vintage game Space Invaders. The software was released open source and was compatible with OpenVIBE. The system...

BCI Signal Classification using a Riemannian-based kernel

Barachant, A., Bonnet, S., Congedo, M., Jutten, C.
20th European Symposium on Artificial Neural Networks, Computational Intelligence and Machine Learning (ESANN 2012), pp. 97-102, 2012

The use of spatial covariance matrix as feature is investigated for motor imagery EEG-based classification. A new kernel is derived by establishing a connection with the Riemannian...

A brain-switch using riemannian geometry

Barachant, A., Bonnet, S., Congedo, M., Jutten, C.
5th International Brain-Computer Interface Conference 2011 (BCI 2011), pp.64-67, 2011

This paper addresses the issue of asynchronous brain-switch. The detection of a specific brain pattern from the ongoing EEG activity is achieved by using the Riemannian geometry,...

Common spatial pattern revisited by riemannian geometry

Barachant, A., Bonnet, S., Congedo, M., Jutten, C.
IEEE International Workshop on Multimedia Signal Processing (MMSP), pp. 472-476, 2010

This paper presents a link between the well known Common Spatial Pattern (CSP) algorithm and Riemannian geometry in the context of Brain Computer Interface (BCI). It will...

Riemannian geometry applied to BCI classification

Barachant, A., Bonnet, S., Congedo, M., Jutten, C.
International Conference on Latent Variable Analysis and Signal Separation, pp. 629-636, 2010

In brain-computer interfaces based on motor imagery, covariance matrices are widely used through spatial filters computation and other signal processing methods. Covariance matrices lie in the space...
