Should we just deprecate / remove the HMM?
We deemed sequence prediction off-topic (Lars' words and I agree) and
there is no core-dev maintaining them.
Is there any project this could move to?

Just anecdotally I can say the goodness of fit and speed seem comparable,
but the models produced are slightly different. I'm working on making a
more comprehensive comparison.

Great reference Robert! Thanks.
Currently I am satisfied with the performance scipy.cluster given my data size.
However, it will be great to have these fast cluster algorithms added. It will
be interesting to look into these.

It was a pretty easy build on Mac -- I just used MacPorts to install and

I'd say Numba is a medium-term consideration. It's enough trouble getting

Thanks for your response, Christian. I experimented with the package. FYI,
there’s a problem with the pypi arff reader. The package claims to handle
numbers but it seems to encode everything (including numbers) as strings, like

hi all. just looking at the one class svm and I'd like to get a

cross validation and that's done by setting the probability=True in

Exactly. Not only would you need cython, it also needs to be a recent version.
people with older versions would get cryptic error messages, leading to
frustrated users and busy mailing lists.
