Belief propagation and learning in convolution multi-layer factor graphs
F. Palmieri, Amedeo Buonanno · 2014
In modeling time series, convolution multi-layer graphs are able to capture long-term dependence at a gradually increasing scale. We present an approach to learn a layered factor graph architecture starting from a stationary latent models for each layer. Simulations of belief propagation are reported for a three-layer graph on a small data set of characters.
