Hi there, 

I've got a couple of questions about the hmm elements of Mahout. 

- when I get models that are made of NaN I guess this is telling me that the 
algorithm can't make a prediction? 
- I can train models with 1 hidden state, or 2 hidden states and once or twice 
with 3 hidden states.. but when I try to train anything more complex it always 
seems to come back with NaNs - even with data sets like 1 2 3 4 5 1 2 3 4 5 1 
2... which in my simple minded view should work well for 4 or 5 hidden states : 
what am I doing wrong? 
- I have used hmmpredict to produce some... predictions! but how can I give it 
a sequence and then ask for the next state? Or should I simply use the code to 
create a custom predictor of my own?

All the best, 

Simon
