Dear Sir,

Thank you for your kind reply. I agree with most of your points but I differ slightly 


My problem is over model validation on continuous time Markov system.
Generally, I understand the theory and can run the kits like or Scikit-learn.
The problem is if I can not fit the data in run time I would be at the mercy of the kit.
So I wanted to know the coding of the computation. 

I am specifically looking at the small python example of Forward, Backward and Viterbi 

I tried to surf the web but did not help much. I do not know much of Scientific forum.

I thought as, NLTK, Scikit-learn are Python implementations so there would be lot 

of people in the room who would know it. 

And I got people like you, so I can not say I am wrong!
