Reading Note : Parameter estimation for text analysis 暨LDA学习小结 原文:http://www.xperseverance.net/blogs/2013/03/1744/ 伟大的Parameter estimation for text analysis!当把这篇看的差不多的时候,也就到了LDA基础知识终结的时刻了,意味着LDA基础模型的基本了解完成了.所以对该模型的学习告一段落,下一阶段就是了解LDA无穷无尽的变种,不过那些不是很有用了…
在Click Model中进行参数预估的方法有两种:最大似然(MLE)和期望最大(EM).至于每个click model使用哪种参数预估的方法取决于此model中的随机变量的特性.如果model中的随机变量都是可以observed,那么无疑使用MLE,而如果model中含有某些hidden variables,则应该使用EM算法. 1. THE MLE ALGORITHM 似然函数为: 则需要预估的参数的在似然函数最大时候的值为: 1)MLE FOR THE RCM AND CTR MODELS…

From: https://alexanderetz.com/2015/04/15/understanding-bayes-a-look-at-the-likelihood/ Reading note. Much of the discussion in psychology surrounding Bayesian inference focuses on priors. Should we embrace priors, or should we be skeptical? When are…

Abstract – In many practical data mining applications such as web page classification, unlabeled training examples are readily available but labeled ones are fairly expensive to obtain. Therefore, semi-supervised learning algorithms such as co-traini…
