    As it is a regularization layer, it is only active at training time.

    Args:
        rate: Float, drop probability (as with `Dropout`).
            The multiplicative noise will have
            standard deviation `sqrt(rate / (1 - rate))`.
        seed: Integer, optional random seed to enable deterministic behavior.

    Call arguments:
        inputs: Input tensor (of any rank).
        training: Python boolean indicating whether the layer should behave in
            training mode (adding dropout) or in inference mode (doing nothing).
