I’m looking for some python implementation (in pure python or wrapping existing stuffs) of HMM and Baum-Welch.
I’ve just searched in google and I’ve found really poor material with respect to other machine learning techniques. Why?
The scikit-learn has an HMM implementation. It was until recently considered as unmaintained and its usage was discouraged. However it has improved in the development version. I cannot vouch for its quality, though, as I know nothing of HMMs.
Disclaimer: I am a scikit-learn developer.
Edit: we have moved the HMMs outside of scikit-learn, to https://github.com/hmmlearn/hmmlearn
