Graphsage graph embedding
GraphSAGE is a convolutional graph neural network algorithm. The key idea behind the algorithm is that we learn a function that generates node embeddings by sampling and aggregating feature information from a node’s local neighborhood. As the GraphSAGE algorithm learns a function that can induce the … See more In this example, you will reproduce the protein role classification task from the original GraphSAGE article. The task is to classify protein roles in terms of their cellular function across various protein-protein interaction … See more As mentioned, we are dealing with a protein-protein interaction network. This is a monopartite network, where nodes represent proteins and relationships represent their … See more To get a baseline f1 score, you will first train the classification model using only the predefined features available for proteins.
