Creates a new optimizer object.
AdaptiveGradientDelta.new(decayRate: number, epsilon: number): OptimizerObject
decayRate: The value that controls the rate of decay.
epsilon: The value to ensure that the numbers are not divided by zero.
AdaptiveGradientDelta:setDecayRate(decayRate: number)
AdaptiveGradientDelta:setEpsilon(epsilon: number)
Reset optimizer’s stored values (excluding the parameters).
AdaptiveGradientDelta:reset()
