Applies Alpha Dropout to the input.
tf.keras.layers.AlphaDropout( rate, noise_shape=None, seed=None, **kwargs )
Alpha Dropout is a Dropout
that keeps mean and variance of inputs to their original values, in order to ensure the self-normalizing property even after this dropout. Alpha Dropout fits well to Scaled Exponential Linear Units by randomly setting activations to the negative saturation value.
Arguments | |
---|---|
rate | float, drop probability (as with Dropout ). The multiplicative noise will have standard deviation sqrt(rate / (1 - rate)) . |
seed | A Python integer to use as random seed. |
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).Arbitrary. Use the keyword argument input_shape
(tuple of integers, does not include the samples axis) when using this layer as the first layer in a model.
Same shape as input.
