Web2 Jul 2024 · We can see that the part subtracted from w linked to regularization isn’t the same in the two methods. When using the Adam optimizer, it gets even more different: in the case of L2 regularization we add this wd*w to the gradients then compute a moving average of the gradients and their squares before using both of them for the update. Whereas the … Webkeras.optimizers.RMSprop(lr=0.001, rho=0.9, epsilon=1e-08, decay=0.0) RMSProp optimizer. It is recommended to leave the parameters of this optimizer at their default values (except …
