关于T,Z, MI

回复: 关于T,Z, MI

二楼的,谢谢哦!但那个仍然没有对Mi值的详细介绍哦!

Mannig举得例子是如果两个词(Ayatollah, Ruhollah)的MI值是18.38的话:

“For example, the mutual information measure tells us that the amount of information we have about the occurrence of Ayatollah at position i in the corpus increase by 18.38 bits if we are told that Ruhollah occurs at position i+1. ...... We could also say that our uncertainty is reduced by 18.38 bits.:

bits 好像是测量信息的单位。如果你觉得还不够详细的话,可以看个让人头大的:
