The method returns (1) the retained edge_index, (2) the edge mask indicating which edges were retained. (3) the node mask indicating which nodes were retained. Parameters edge_index ( LongTensor) – The edge indices.
WebFeb 20, 2024 · To convert an adjacency matrix to the adjacency list. Create an array of lists and traverse the adjacency matrix. If for any cell (i, j) in the matrix “ mat [i] [j] != 0 “, it means there is an edge from i to j, so insert j in the list at i-th position in the array of lists.

WebJan 24, 2024 · More formally, putting the adjacency matrix between two \(\tilde{D}^{1/2}\) results in scaling each adjacency value by \(\frac{1}{\sqrt{D_iD_j}}\) where \(i\) and \(j\) are some connected nodes. Hence, when the connected nodes have a lot of other connections (i.e. \(D\) is large), features get multiplied by a smaller value and are discounted. kw in terms of kjWebJan 24, 2024 · It appears there are actually quite a few ways to do this.
