Bayesian learning and inference for state space models

This package has fast and flexible code for simulating, learning, and performing inference in a variety of state space models. Currently, it supports

  • Hidden Markov Models HMM
  • Auto-regressive HMMs ARHMM
  • Input-output HMMs IOHMM
  • Hidden Semi-Markov Models HSMM
  • Linear Dynamical Systems LDS
  • Switching Linear Dynamical Systems SLDS
  • Recurrent SLDS rSLDS
  • Hierarchical extensions of the above
  • Partial observations and missing data

It supports the following observation models

  • Gaussian
  • Student’s
  • Bernoulli
  • Poisson
  • Categorical
  • Von Mises
