看了文章,觉得有些地方还是搞不透
什么是Markov models ?
还有weighted or stochastic grammar, algebraic grammar
有没有这方面的中文介绍啊?

hidden Markov model
http://www.nist.gov/dads/HTML/hiddenMarkovModel.html
(data structure)

Definition: A variant of a finite state machine having a set of states, Q, an output alphabet, O, transition probabilities, A, output probabilities, B, and initial state probabilities, Π. The current state is not observable. Instead, each state produces an output with a certain probability (B). Usually the states, Q, and outputs, O, are understood, so an HMM is said to be a triple, (A, B, Π).

Formal Definition: After Michael Cohen's lectures for CN760.

Thanks for the explanation,XU
