互信息![]() ![]() ![]() 在概率论和信息论中,两个随机变量的互信息(Mutual Information,简称MI)或转移信息(transinformation)是变量间相互依赖性的量度。不同于相关系数,互信息并不局限于实值随机变量,它更加一般且决定着联合分布 p(X,Y) 和分解的边缘分布的乘积 p(X)p(Y) 的相似程度。互信息是点间互信息(PMI)的期望值。互信息最常用的单位是bit。
英语百科
Mutual information 互信息![]() ![]() ![]() In probability theory and information theory, the mutual information (MI) of two random variables is a measure of the mutual dependence between the two variables. More specifically, it quantifies the "amount of information" (in units such as bits) obtained about one random variable, through the other random variable. The concept of mutual information is intricately linked to that of entropy of a random variable, a fundamental notion in information theory, that defines the "amount of information" held in a random variable. |
