How autoencoders work
Web17 de fev. de 2024 · How do Autoencoders Work? It works using the following components doing the aforementioned tasks: 1) Encoder: The encoder layer encodes the input image into a compressed representation in a reduced dimension. The compressed image is obviously the distorted version of the original image. WebIn Chapter 16, Deep Learning, we saw that neural networks are successful at supervised learning by extracting a hierarchical feature representation that's usefu
