Keras is a high-level neural networks API, written in Python, and can run on top of TensorFlow, CNTK, or Theano. It was developed with a focus on enabling fast experimentation. The advantages of using Keras emanates from the fact that it focuses on being user-friendly, modular, and extensible What are autoencoders? Autoencoding is a data compression algorithm where the compression and decompression functions are 1) data-specific, 2) lossy, and 3) learned automatically from examples rather than engineered by a human. Additionally, in almost all contexts where the term autoencoder is used, the compression and decompression functions are implemented with neural networks For any Keras layer (Layer class), can someone explain how to understand the difference between input_shape, units, dim, etc.?For example the doc says units specify the output shape of a layer..
