Is Rectified Adam actually *better* than Adam?

October 7, 2019

Is the Rectified Adam (RAdam) optimizer actually better than the standard Adam optimizer? According to my 24 experiments, the answer is no, typically not (but there are cases where you do want to use it instead of Adam). In Liu…

Rectified Adam (RAdam) optimizer with Keras

September 30, 2019

In this tutorial, you will learn how to use Keras and the Rectified Adam optimizer as a drop-in replacement for the standard Adam optimizer, potentially leading to a higher accuracy model (and in fewer epochs). Today we’re kicking off a…

Keras: Starting, stopping, and resuming training

September 23, 2019

In this tutorial, you will learn how to use Keras to train a neural network, stop training, update your learning rate, and then resume training from where you left off using the new learning rate. Using this method you can…
