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 ---- Dr. Simon Thompson Chief Researcher, Customer Experience. BT Research. BT plc. PP11J.
