 ```sspy``` serves as a Python library to bring together implementations of solving state space models, particularly methods that learn system dynamics. The library is being implemented as part of an ongoing survey into learning state space dynamics. At present, the basic utilities for working with state space implementing filters and smoothers are being implemented. Later, implementations of papers will be added and benchmarked.

 The base of this library is inspired by the [EKF/UKF Toolbox for MATLAB](http://becs.aalto.fi/en/research/bayes/ekfukf/) by Särkkä, Hartikainen, and Solin.
