Rao-Blackwellized particle filters for quasiperiodic Gaussian processes

A Rao-Blackwellized particle filter for a model with Poisson-distributed observations whose log-intensity follows a quasiperiodic Gaussian process.

Documentation in http://www.juhokokkala.fi/blog/posts/rao-blackwellized-particle-filters-for-quasiperiodic-gaussian-processes/

Requirements

NumPy, GPy. matplotlib for plotting. Python 3.5 due to the matrix multiplication operator.

Files

rbpf.py -- contains the filter and the Particle independent Metropolis-Hastings sampler. test.py -- script for running the experiment in the blog post. resampling.py -- resampling algorithms (c) Roger R Labbe Jr.
