展望监视器
这是一辆车展厅管理代码。
在我暑期培训课程期间,它被分配给我。客户被称为前景,存储在数据库,同时提供一个称为热辣的字段中。热辣标志 prospect(customer) 很快会来进行购买。不同层次是热辣的热、 介质和冷。标记一样热的客户是一个如何有可能使购买在未来数天。中期前景预计将在几个星期购买。同样的冷的前景可能需要几个月要购买。
该项目分为两个模块: 管理和监控。
ADMIN 就像商店经理,看到过店里的工作。他是一个与大多数电力系统中。他可以执行操作,如添加新的监视器、 更改他们的密码和删除它们。
监视器是销售的人。

tf-idf Java实现,还是很不错的
资源描述TF-IDF(term frequency–inverse document frequency)是一种用于资讯检索与资讯探勘的常用加权技术, TFIDF的主要思想是:如果某个词或短语在一篇文章中出现的频率TF高,并且在其他文章中很少出现,则认为此词或者短语具有很好的类别区分能力,适合用来分类。TFIDF实际上是:TF * IDF,TF词频(Term Frequency),IDF反文档频率(Inverse Document Frequency)。TF表示词条在文档d中出现的频率。IDF的主要思想是:如果包含词条t的文档越少,也就是n越小,IDF越大,则说明词条t具有很好的类别区分能力。如果某一类文档C中包含词条t的文档数为m,而其它类包含t的文档总数为k,显然所有包含t的文档数n=m + k,当m大的时候,n也大,按照IDF公式得到的IDF的值会小,就说明该词条t类别区分能力不强。但是实际上,如果一个词条在一个类的文档中频繁出现,则说明该词条能够很好代表这个类的文本的特征,这样的词条应该给它们赋予较高的权重,并选来作为该类文本的特征词以区别与其它类文档。这就是IDF的不足之处。这里采用了外部插件IKAnalyzer-2012.jar,用其进行分词,插件和测试文件可以从这里下载

希爾伯特黃轉換簡介(Hilbert Huang Transform)
Hilbert-Huang (HHT) 轉換方法是黃鍔根據近代知名數學家 Hilbert 的數學理論設計,做爲分析非穩定或非線性的訊號The Hilbert–Huang transform (HHT) is a way to decompose a signal into so-called intrinsic mode functions (IMF) along with a trend, and obtain instantaneous frequency data. It is designed to work well for data that is nonstationary and nonlinear. In contrast to other common transforms like the Fourier transform, the HHT is more like an algorithm (an empirical approach) that can be applied to a data set, rather than a theoretical tool.

Apache Ant
Apache Ant is a Java library and command-line tool whose mission is to drive processes described in build files as targets and extension points dependent upon each other. The main known usage of Ant is the build of Java applications. Ant supplies a number of built-in tasks allowing to compile, assemble, test and run Java applications. Ant can also be used effectively to build non Java applications, for instance C or C++ applications. More generally, Ant can be used to pilot any type of process which can be described in terms of targets and tasks.
