It should be noted that this pull request now includes the changes outlined in the discussion of Issue #668.
This include changes to numerous model
classes, as well as the Partifle filter. Currently these changes only affect the Ensemble and Particle filters respectivley.
Here is my implementation of the Ensemble Square Root filter Updater which I presented at last year's Fusion Conference.
A full writeup of the algorithm itself, as well as design philosophy can be found in my paper titled "Implementation of Ensemble Kalman Filters in Stone Soup". The contribution here (in this particular pull request) is specifically a new updater. The predictor of the EnKF and EnSRF are shared, but the EnSRF assimilates measurements without adding noise which typically results in lower sampling error and thus higher accuracy.
One other thing to note. Is that this pull request also fixes issue #668 which caused both the
EnsemblePredictor
and thepredict_measurement
method in the EnKF (the latter of which is inherited by the EnSRF).
