Variational Bayesian Linear Gaussian State-Space Models

MATLAB implementation of a Bayesian approach to Linear Gaussian State-Space Models (LGSSMs), also called Linear Dynamical Systems, using Gaussian and Wishart prior distributions on the model parameters. Model intractability is addressed with a variational approximation scheme, where inference is reformulated such that any standard Kalman filtering/smoothing routine can be employed (here we implemented the standard predictor-corrector Kalman filtering routine and the Rauch-Tung-Striebel smoothing routine).
