Graphical mutual information
WebMar 24, 2024 · In addition, to remove redundant information irrelevant to the target task, SGIB also compares the mutual information between the first-order graphical encodings of the two subgraphs. Finally, the information bottleneck is used as the loss function of the model to complete the training and optimization of the objective function. http://www.ece.virginia.edu/~jl6qk/paper/TPAMI22_GMI.pdf

WebMar 5, 2024 · Computing the conditional mutual information is prohibitive since the number of possible values of X, Y and Z could be very large, and the product of the numbers of possible values is even larger. Here, we will use an approximation to computing the mutual information. First, we will assume that the X, Y and Z are gaussian distributed. WebApr 15, 2024 · Graph convolutional networks (GCNs) provide a promising way to extract the useful information from graph-structured data. Most of the existing GCNs methods usually focus on local neighborhood information based on specific convolution operations, and ignore the global structure of the input data.
