Python package for efficient Bayesian evidence computation
Project description
Python package to efficiently compute the Learnt Harmonic Mean estimator of the Bayesian evidence
Harmonic is an open source and fully documented python implementation of the Learnt Harmonic Mean estimator for the Bayesian evidence or marginal likelihood. In practice one uses chains gathered separately through MCMC sampling software to train one of the Harmonic machine learning models which then stabilize the harmonic mean estimator.
