A quick look at the string

Most of the time,We need to look at many strings,To determine the specific content filtering out。For example, through the input method which pocketed,We need to use auxiliary code word to filter out candidates need。

Based on Dynamic Programming sentence input method

In General,We will not call it on the issue of dynamic programming algorithm is "Dynamic Programming”,But called "Hidden Markov Models”,but,If we simply use the dynamic programming algorithm to solve a common directed acyclic graph,Then it can only be said to be dynamic planning ......

This time we want for the,It is based on the sentence input method thesaurus。The hidden Markov model is not based on the state transition Solution。

Being Chinese Wikipedia corpus

Recently doing input method thesaurus,Implement new sentence input model,(Based on input model sentence the word I would talk back before),The new model is based on the input sentence HMM (I.e.Hidden Markov Models) To do,Of course,Due to limited funds, I personally equipment,Only the second order matrix。But even so,Model still need training。

of course,Not to say that with the novels and to train bad,Just hard to find the rows[……]
