Mutual information is used in determining the similarity of two different clusterings of a dataset. As such, it provides some advantages over the traditional Rand index. Mutual information of words is often used as a significance function for the computation of collocations in corpus linguistics. Se mer 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" … Se mer Intuitively, mutual information measures the information that $${\displaystyle X}$$ and $${\displaystyle Y}$$ share: It measures how much … Se mer Several variations on mutual information have been proposed to suit various needs.
