click model是用于对用户在搜索结果页上的点击行为进行建模。我们讨论的这些basic click models 能够计算出给定一个document后的点击概率 ,以及在给定相同session中前面的点击事件后对特定document进行点击的概率 。前者可以用于预估document的CTR,后者则可以用于模拟点击行为,或者用于计算最大似然。 对于RCM,RCTR,DCTR,PB...
1)MLE FOR THE RCM AND CTR MODELS RCM: RCTR: DCTR: 这几个例子都比较简单,都是简单地基于统计的方式。分子是各自事件的点击数,而分母是各自事件的展现数。 2)MLE FOR DCM 在DCM中,从最后一次点击位置的document开始,attractiveness变量就没法obsesrved了,我们不知道是用户因为对最后一次点击的document不satisf...

(DSSM)Learning Deep Structured Semantic Models for Web Search using Clickthrough Data 第一层是embedding层,输入是multihot,因此丢失了位置信息。 中间层是线性+激活层,激活函数是tanh 最后一层是cos距离 训练的时候采用1:4的采样比例,做negative sample softmax。loss采用负对数似然概率。

ClickModels is a small set of Python scripts for the user click models initially developed at Yandex. A Click Model is a probabilistic graphical model used to predict search engine click data from past observations. This project is aimed to deal with cli
This functionality allows such applications to be deployed with simpler deployment models such as XCOPY and ClickOnce, overcoming the traditional factors that make the deployment of COM components sometimes difficult.ClickOnce is a new deployment technology for Windows Forms apps that is being introduced...
