GradientStep

trait GradientStep extends GradientOptimizer

Base trait for optimizers whose operational form can be described as

  1. get a gradient 2. do some transformation to it 3. compute a learning rate 4. add it to the weights

Traits which extend this one can have things like parameter averaging or MIRA learning rates or adaptive learning rates for free.
