Pomegranate: fast and flexible probabilistic models in python
summary
pomegranate claims a fast, flexible Python probabilistic toolkit that beats scikit-learn in benchmarks by using an aggressive C/Cython implementation and multithreaded Cython backend that releases the GIL. it implements concrete, composable models — distributions, GMMs, HMMs, Bayesian networks and mixtures of HMMs with tied emissions — supports out‑of‑core sufficient‑statistics fitting and shows consistent speedups (2x typical, tens of x for some routines) while producing comparable results.
