潜在狄利克雷分配(LDA, Latent Dirichlet allocation)是一种生成概率模型(generative probabilistic model),该模型假设每个文档具有类似于概率潜在语义索引模型的主题的组合。 简而言之,LDA背后的思想是,每个文档可以通过主题的分布来描述,每个主题可以通过单词的分布来描述。

常用模型:Latent Dirichlet Allocation (LDA), pLSA, pLSI等,是一种无监督的学习过程; C. N-Grams N-Gram是一种基于统计语言模型的算法。它的基本思想是将文本里面的内容按照字节进行大小为N的滑动窗口操作,形成了长度是N的字节片段序列。 >>> generate_ngrams('this is a sample text', 2) # [['this',...
我们可以直接使用textEnter.get()访问text,但我们将使用一个Tkinter StringVar()对象来间接访问它。如果需要,这将允许我们将正在处理的数据与处理 GUI 布局的代码分开。enycrptvalue变量在使用.set()命令时会自动更新它所链接到的Entry小部件(并且.get()命令会从Entry小部件获取最新的值)。
导读:Python本身的数据分析功能并不强,需要安装一些第三方扩展库来增强其相应的功能。本文将对NumPy、SciPy、Matplotlib、pandas、StatsModels、scikit-learn、Keras、Gensim等库的安装和使用进行简单的介绍。 作者:张良均 谭立云 刘名军 江建明 来源:大数据DT(ID:hzdashuju) ...
