WebJun 24, 2024 · This requirement dictates the structure of the Auto-encoder as a bottleneck. Step 1: Encoding the input data The Auto-encoder first tries to encode the data using the initialized weights and biases. Step 2: Decoding the input data The Auto-encoder tries to reconstruct the original input from the encoded data to test the reliability of the encoding. WebJun 3, 2024 · I am using a graph autoencoder to perform link prediction on a graph. The issue is that the number of negative (absent) edges is about 100 times the number of positive (existing) edges.
