Looking at
https://github.com/daoliker/viterbi/blob/master/viterbi_decoder.cc#L35
shouldn't that be
hid_seq[t] = psi[t + 1][hid_seq[t + 1]];
it seems off-by-one for my glance; especia…

I understand that it has not been published, and I do not know if it has been benchmarked in any way. But in theory Pangenie offers variant phasing via an hmm-based algorithm, which seems sensible.

Hi everyone,
I want to preface this question by saying I'm not really an expert on CRF or the Viterbi algorithm so please bear with me :).
I ran the simple code from a previous issue here.

Hi,
I am confused wrt lines 26 and 27 of the viterbi implementation:
` trellis[:, t] = (trellis[:, t-1, None].dot(self.Obs(obs[t]).T) * self.transProb).max(0)
backpt[:, t] = (np.tile(t…

Thank you for sharing the nicely commented code. I am reading the accompanying paper (Taylor et al 2019 Estimating relatedness) and trying to apply this method to our own SNP data. However, I am not v…

Hello,
I've been fiddling about with the MultinomialHMM class, and have a few questions:
It seems that the implementation of the model is unable to handle a set of observable symbols that is big…

Is it possible to add logsumexp-plus (or am I missing it) ? Would be really useful, but seems a bit more complex than the other to do.
