steps is a checkpoints (number of iterations) at which scales will be applied.

scales is a coefficients at which learning_rate will be multiplied at this checkpoints. Determines how the learning_rate will be changed during increasing number of iterations during training.

Both of them are related to each other and they have the same amount.

steps=200,400,600,20000,30000

scales=2.5,2,2,.1,.1

At step 200 the scales is 2.5, step 400 the scale is 2, etc.
