The four steps of multi-view drug similarity network fusion strategy. Step 1: Take different similarity networks of drugs as input and learn the embeddings of drugs from different networks. Step 2: Integrate the embeddings of drugs with the multi-view attention mechanism. Step 3: Reconstruct the integrated drug network through dot product operation on the integrated drug features. Step 4: Train MIDTI by minimizing reconstruction error between the reconstructed network and each original drug similarity network.
