“纸上得来终觉浅,绝知此事要躬行”,在继续翻译《HMM
学习最佳范例
》之前,这里先补充几个不同程序语言实现的HMM版本,主要参考了维基百科。读者有兴趣的话可以研究一下代码,这样对于HMM的学习
会深刻很多!

C语言版:

1、 HTK(Hidden Markov Model Toolkit):

  HTK是英国剑桥大学开发的一套基于C语言的隐马尔科夫模型工具箱,主要应用于语音识别、语音合成的研究,也被用在其他领域,如字符识别和DNA排序
等。HTK是重量级的HMM版本。

2、 GHMM Library:

  The General Hidden Markov Model library (GHMM) is a freely available
LGPL-ed C library implementing efficient data structures and algorithms
for basic and extended HMMs.

3、 UMDHMM(Hidden Markov Model Toolkit):

  Hidden Markov Model (HMM) Software: Implementation of
Forward-Backward, Viterbi, and Baum-Welch algorithms.

  这款属于轻量级的HMM版本。

Java版:

4、 Jahmm Java Library (general-purpose Java library):

  Jahmm (pronounced “jam”), is a Java implementation of Hidden Markov
Model (HMM) related algorithms. It’s been designed to be easy to use
(e.g. simple things are simple to program) and general purpose.

Malab版:

5、 Hidden Markov Model (HMM) Toolbox for Matlab:

  This toolbox supports inference and learning for HMMs with discrete
outputs (dhmm’s), Gaussian outputs (ghmm’s), or mixtures of Gaussians
output (mhmm’s).

Common Lisp版:

6、CL-HMM Library (HMM Library for Common Lisp):

  Simple Hidden Markov Model library for ANSI Common Lisp. Main
structures and basic algorithms implemented. Performance speed
comparable to C code. It’s licensed under LGPL.

Haskell版:

7、The hmm package (A Haskell library for working with Hidden Markov
Models):

  A simple library for working with Hidden Markov Models. Should be
usable even by people who are not familiar with HMMs. Includes
implementations of Viterbi’s algorithm and the forward algorithm.

  注:Haskell是一种纯函数式编程语言,它的命名源自美国数学家Haskell Brooks
Curry,他在数学逻辑方面上的工作使得函数式编程语言有了广泛的基础。

是否还有C++版、Perl版或者Python版呢?欢迎补充!
