双门限端点检测。因为低噪声导致假过零率的产生，进行了算法改进。可以直接调用函数运行，亲测-Dual threshold endpoint detection. Because of the low noise cause false over-produce zero rate, the algorithm was improved. It can directly call the function run, pro-test

首先声明，这是别人写的LDA主题模型代码，本人测试过，可以运行，但是输出跟输出有点不尽人意，输入的是词的序号和该词在文档中出现的次数，要是可以直接读取文档就完美了。输出是主题以及词在该主题出现的概率，其中得到的主题我就看不懂了，不知道是算法问题，还是因为我的水平有限。在研究LDA主题模型的朋友，可以下载试一下-First statement, which is written by someone else LDA topic model code, I tested, you can run,

在机器学习中，随机森林由许多的决策树组成，因为这些决策树的形成采用了随机的方法，所以叫做随机森林。-In machine learning, Random Forests decision tree composed of many, because of the formation of these decision trees using random method, so called Random Forest.

Hive编程指南源代码，里面含有数据源，例如股票的信息。因为自己平时也要用积分下载资源，所以设置了一分。-Hive Programming Guide source code, which contains the data source, such as stock information. Because they usually have to use points to download resources, so we set up a point.
