WebJul 3, 2024 · Learning with graphs has attracted significant attention recently. Existing representation learning methods on graphs have achieved state-of-the-art performance on various graph-related tasks such as node classification, link prediction, etc. However, we observe that these methods could leak serious private information. For instance, one … Webmutual information between two feature point sets and find the largest set of matching points through the graph search. 3.1 Mutual information as a similarity measure Mutual information is a measure from information theory and it is the amount of information one variable contains about the other. Mutual information has been used extensively as a

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. See more 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" … See more Intuitively, mutual information measures the information that $${\displaystyle X}$$ and $${\displaystyle Y}$$ share: It measures how much knowing one of these variables reduces … See more Several variations on mutual information have been proposed to suit various needs. Among these are normalized variants and generalizations to more than two variables.
