Learning rate finder and Cyclical Learning Rates for Neural Networks with CIFAR10 – Keras R

2019-01-01
By: jlao
On: 01/01/2019

In this post, we will verify the technique developed in 2015 and described in the paper Cyclical Learning Rates for Training Neural Networks. This technique describes a new method for changing the learning rate on each iteration (or batch) inread more →

Changing learning rate during training on each batch/iteration (using callbacks in R keras)
