Graph mutual information
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. Metric Many applications … See more • Data differencing • Pointwise mutual information • Quantum mutual information • Specific-information See more Let $${\displaystyle (X,Y)}$$ be a pair of random variables with values over the space $${\displaystyle {\mathcal {X}}\times {\mathcal {Y}}}$$. If their joint distribution is $${\displaystyle P_{(X,Y)}}$$ and the marginal distributions are $${\displaystyle P_{X}}$$ See more Nonnegativity Using Jensen's inequality on the definition of mutual information we can show that See more In many applications, one wants to maximize mutual information (thus increasing dependencies), which is often equivalent to … See more WebApr 13, 2024 · Information without innovation is just data.

WebTo this end, we present a novel GNN-based MARL method with graphical mutual information (MI) maximization to maximize the correlation between input feature information of neighbor agents and output high-level hidden feature representations. The proposed method extends the traditional idea of MI optimization from graph domain to … WebIn this work, we study node classification in a hierarchical graph perspective which arises in many domains such as social network and document collection. In the hierarchical graph, each node is represented with one graph instance. We propose the Hierarchical Graph Mutual Information (HGMI) to model consistency among different levels of hierarchical …
