Sparse Graphical Linear Dynamical Systems

no code implementations6 Jul 2023 Emilie Chouzenoux, Victor Elvira

This work proposes a novel approach to fill this gap by introducing a joint graphical modeling framework that bridges the static graphical Lasso model and a causal-based graphical approach for the linear-Gaussian SSM.

Bayesian data fusion with shared priors

no code implementations14 Dec 2022 Peng Wu, Tales Imbiriba, Victor Elvira, Pau Closas

When data is only available in a distributed fashion or when different sensors are used to infer a quantity of interest, data fusion becomes essential.

The Incremental Proximal Method: A Probabilistic Perspective

no code implementations12 Jul 2018 Ömer Deniz Akyildiz, Victor Elvira, Joaquin Miguez

We then carry out this observation to a general sequential setting: We consider the incremental proximal method, which is an algorithm for large-scale optimization, and show that, for a linear-quadratic cost function, it can naturally be realized by the Kalman filter.

The Recycling Gibbs Sampler for Efficient Learning

no code implementations21 Nov 2016 Luca Martino, Victor Elvira, Gustau Camps-Valls

The key point for the successful application of the Gibbs sampler is the ability to draw efficiently samples from the full-conditional probability density functions.
