1.简介 SRILM是通过统计方法构建语言模型,主要应用于语音识别,文本标注和切分,以及机器翻译等. SRILM支持语言模型的训练和评测,通过训练数据得到语言模型,其中包括最大似然估计及相应的平滑算法:评测是计算测试集的困惑度.其最基础和最核心的模块是n-gram模块,包括两个工 具:ngram-count和ngram,被用来估计语言模型和计算语言模型的困惑度. 2.使用方法 (1).语料初始化 a.数据清洗        b.分词(以空格划分)        c.将数据分为训练集和测试集 (2

SRILM是一个建立和使用统计语言模型的开源工具包,从1995年开始由SRI 口语技术与研究实验室(SRI Speech Technology and Research Laboratory)开发,现在仍然不断推出新版本,被广泛应用于语音识别.机器翻译等领域.这个工具包包含一组C++类库.一组进行语言模型训练和应用的可执行程序等.利用它可以非常方便地训练和应用语言模型.给定一组连续的词,调用SRILM提供的接口,可以得到这组词出现的概率. http://www.jianshu.com/p/5b1

RIFF file format RIFF全称为资源互换文件格式(Resources Interchange File Format),是Windows下大部分多媒体文件遵循的一种文件结构.RIFF文件所包含的数据类型由该文件的扩展名来标识,能以RIFF格式存储的数据有: 音频视频交错格式数据 .AVI 波形格式数据 .WAV 位图数据格式 .RDI MIDI格式数据 .RMI 调色板格式 .PAL 多媒体电影 .RMN 动画光标 .ANI 其他的RIFF文件 .BND CHUNK chunk是

Properties文件格式说明 Properties继承自Hashtable,是由一组key-value的集合. 在Java中,常用properties文件作为配置文件.它的格式是什么样的呢? 下图是一个用于展示格式的properties文件 下面是测试结果: properties文件的书写要求总结: 1.注释内容由 # 或者! 开头 2.key,value之间用 = 或者 : 分隔.一行中既有=也有:时,第一个(或者=或者:)将作为key,value分隔符. 3.key 不能换行,value

      了解JAVA的Class文件结构有助于掌握JAVA语言的底层运行机制,我在学习的过程中会不断的与ELF文件格式作对比(当然他们的复杂程度.格式相去甚远,比如可执行ELF的符号表解析在静态链接阶段已经完成(除了动态链接库是在动态链接阶段完成),而Class的符号解析都是在类加载后动态完成的),由于在以前学习的时候发现网上关于Class文件结构的图都不是很详细,而我是一个喜欢图示的人,所以就自己动手画了一个(其中大部分图标来自<<深入理解JAVA虚拟机第二版>>),图片很大

一.生成dex文件 我们可以通过java文件来生成一个简单的dex文件 编译过程: 首先编写java代码如下: (1) 编译成 java class 文件 执行命令 : javac Hello.java 编译完成后 ,目录下生成 Hello.class 文件 (2) 编译成 dex 文件 dx --dex --output=Hello.dex Hello.class 编译正常会生成 Hello.dex 文件 00 34指明jdk版本,这个原因是jdk版本过高了,我们得使用1.6版本的JDK来进行

一. dex文件头 (1) magic value 在DexFile.c   dexFileParse函数中 会先检查magic opt 啥是magic opt呢? 我们刚刚从cache目录拷贝出来的那个 前面的dey 036就是magic opt 在源码中会先解析magic opt,然后重设dexfile指针 重设magic opt指针后开始解析magic value 这 8 个 字节一般是常量.数组的值可以转换为一个字符串如下 : { 0x64 0x65 0x78 0x0a 0x30 0x3
