Works on simulation-based inference

These publications are related to the research topic that I started developping during my post-doc and is currently my main topic of interest. 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.
