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. WebThe input graph data is encoded by the encoder. The output of encoder is the input of decoder. Decoder can reconstruct the original input graph data.
