Mutual information 不是应该越小越能区分开来吗?

同学你好!
The mutual information value will be equal to 0 if the token’s distribution in all text classes is the same. The MI value approaches 1 as the token in any one class tends to occur more often in only that particular class of text.
high MI value说明包含的信息较多,并不是越小包含信息越多。
