[mlpack-git] [mlpack/mlpack] Issues of HMM training (#638)

[yuanjinq]

Hi, I'm new to HMM and I'm trying to use Mlpack to train a model of Gaussian HMM with a few observation sequences. So I used the mlpack_hmm_train with following command:
mlpack_hmm_train -i 11.txt -n 4 -t gaussian -o 11out.xml

Then I went to the model file and try to find the emissions and transform matrix. I found that the transform matrix are uniform and every emission are the same with a strange value. Then I changed different observation sequences, the result were similar.

Did I do the training right? I read through the document and didn't find the solution. Thank you.
