Nadam - Keras
https://keras.io/api/optimizers/NadamOptimizer that implements the NAdam algorithm. Much like Adam is essentially RMSprop with momentum, Nadam is Adam with Nesterov momentum. Arguments. learning_rate: A Tensor or a floating point value. The learning rate. beta_1: A float value or a constant float tensor. The exponential decay rate for the 1st moment estimates.
