Information gain calculates the reduction in entropy or surprise from transforming a dataset in some way. 其中 是群集 中的样本数, 是群集 中的样本数,群集U和V之间的互信息为:. This is the class and function reference of scikit-learn. 互信息是对同一数据的两个标签之间相似度的度量。. 简介 互信息(Mutual Information)是信息论中的概念,用来衡量两个随机变量之间的相互依赖程度。对于Mutual Information的介绍会用到KL散度(K... 登录 注册 写文章. Mutual Information Based Score. According to the below formula, we normalize each feature by subtracting the minimum data value from the data variable and then divide it by the range of the variable as shown–. The mutual_info_score and the mutual_info_classif they both take into account (even if in a different way, the first as a denominator, the second as a numerator) the integration volume over the space of samples.
