Link Prediction and Node Classification Based on Multitask Graph Autoencoder

Algorithm 1

Mixed local neighbor and path.
Input: edge list
Output: similarity matrix, AUC score
1: Input adjacency matrix
2: Divide all edges into the training set and probe set
3: Construct the third-order path matrix with attenuation parameters
4: Construct optimized common neighbor matrix
5: Construct matrix based on the method of preferential attachment
6: Calculate the similarity matrix that incorporates multiple methods
7: Calculate the AUC score of the MLNP index
