I've run into some difficulties with hmm.GaussianHMM recently, and I assume
it's because of poorly documented element shapes.
Say, I want an HMM with 2 hidden states that emit 1-dimensional variables.
Should means be np.array([300,-300]) or np.array([[300],[300]])? Should
observation sequence be [observation1, observation2, ... , observationN] or
[[observation1],[observation2], ... ]? Probably both times second answer is
correct (first just refuses to run Viterbi), but I'd like someone to
explain it to me.
And how do I help with documenting, if I manage to understand this?
Best regards,
