#initialize(lr = 0.0001, alpha: 0.95, eps: 0.0001, clip_norm: nil) ⇒ RMSPropGraves

Returns a new instance of RMSPropGraves.

Parameters:

  • lr (Float) (defaults to: 0.0001) —

    Learning rate.

  • alpha (Float) (defaults to: 0.95) —

    Moving average index of past slopes.

  • eps (Float) (defaults to: 0.0001) —

    Value to avoid division by zero.
