Specifically, the accuracy we managed to get in 30 epochs (which is the necessary time for SGD to get to 94% accuracy with a 1cycle policy) with Adam and L2 regularization was at 93.96% on average, going over 94% one time out of two. We consistently reached values between 94% and 94.25% with Adam and weight decay.

Defaults to "Adam". @compatibility(eager) When eager execution is enabled, learning_rate, beta1, beta2, and epsilon can each be a callable that takes no arguments and returns the actual value to use. This can be useful for changing these values across different invocations of optimizer functions. @end_compatibility

The learning rate decay in the Adam is the same as that in RSMProp (as you can see from this answer), and that is kind of mostly based on the magnitude of the previous gradients to dump out the oscillations. So the exponential decay (for a decreasing learning rate along the training process) can be adopted at the same time.

For an example of The rate in which the learning rate is decayed is based on the parameters to the polynomial function. Learning rate decay / scheduling You can use a learning rate schedule to modulate how the learning rate of your optimizer changes over time: lr_schedule = keras.optimizers.schedules.ExponentialDecay(initial_learning_rate=1e-2, decay_steps=10000, decay_rate=0.9) optimizer = keras.optimizers.SGD(learning_rate=lr_schedule) Learning rate in … 2020-10-03 I wanna implement learing rate decay while useing Adam algorithm.
