Works on simulation-based inference

These publications are related to the research topic that I’ve been developping during my post-doc. Several collaborations are currently under progress with researchers from the University of Liège, Brown University, and the ICTP in Italy.

Works on transfer learning

Both journal papers lay the mathematical foundations of my contributions in transfer learning for data defined in a SPD manifold. The other conference papers were all oral presentations, showing the growing interest of the research community in these methods.

Works on dimensionality reduction

These were the first published works of my Ph.D. thesis. They are based on the widely known mathematical framework of diffusion maps and extend it to the case of data points defined in the symmetric-positive definite manifold. Reference [8] is the first work in the literature, to the best of my knowledge, that applies these concepts to the analysis of multivariate time series.
  1. PLC Rodrigues, M Congedo, C Jutten. “Multivariate time-series analysis via manifold learning”. IEEE Statistical Signal Processing Workshop (SSP 2018), June, 2018, Fribourg-en-Brisgau, Germany. Paper available at hal-01868167. Related code available here.
  2. PLC Rodrigues, F Bouchard, M Congedo, C Jutten. “Dimensionality reduction for BCI classification using Riemannian geometry”. 7th Graz Brain-Computer Interface Conference. September, 2017, Graz, Austria. Oral presentation. Paper available at hal-01591258. Related code available here.
  3. F Bouchard, PLC Rodrigues, J Malick, M Congedo. “Réduction de dimension pour la séparation aveugle de sources”. XXVIème colloque GRETSI (GRETSI 2017), September, 2017. Juan-Les-Pins, France. Paper available at hal-01589766.

Paper available at hal-01563153.
