几种不同语言版本的HMM实现

详细信息:

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.

GHMM主页:http://www.ghmm.org/

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C语言HMM版本。

C++版:

1、http://www.cs.ualberta.ca/~lindek/hmm.htm

2、http://www.shokhirev.com/nikolai/abc/alg/hmm/hmm.html

以上两个是C++版本的,但是实现的是离散型的HMM。

Java版:

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.

Python版:

Malab版:

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:

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:

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。

CDHMM C++版:

连续HMM的C++实现:http://download.csdn.net/detail/luxiaoxun/

注:这是网上找的,里面实现有个连续的HMM-GMM的实现,代码写的很好,有些地方需要根据自己的需求改动。
