Keras/TF implementation of AdamW, SGDW, NadamW, and Warm Restarts, based on paper Decoupled Weight Decay Regularization - plus Learning Rate Multipliers. Features. Weight decay fix: decoupling L2 penalty from gradient.Why use? Weight decay via L2 penalty yields worse generalization, due to decay not working properly; Weight decay via L2 …
Adam - Keras
https://keras.io/api/optimizers/adamAdam optimization is a stochastic gradient descent method that is based on adaptive estimation of first-order and second-order moments. According to Kingma et al., 2014 , the method is " computationally efficient, has little memory requirement, invariant to diagonal rescaling of gradients, and is well suited for problems that are large in terms ...

Adam (learning_rate = 0.01) model. compile (loss = 'categorical_crossentropy', optimizer = opt) You can either instantiate an optimizer before passing it to model.compile(), as in the above example, or you can pass it by its string identifier.
