Graph mutual information
WebApr 5, 2024 · Recently, maximizing mutual information has emerged as a powerful tool for unsupervised graph representation learning. Existing methods are typically effective in capturing graph information from the topology view but consistently ignore the node feature view. To circumvent this problem, we propose a novel method by exploiting … WebDec 5, 2024 · To effectively estimate graph mutual information, we design a dynamic neighborhood sampling strategy to incorporate the structural information and overcome the difficulties of estimating mutual information on non-i.i.d. graph-structured data.

WebIn 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 shannons (), nats or hartleys) obtained about one random variable by observing the other random … WebSep 7, 2024 · In this article.

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.
