tf.layers.dropout(inputs, rate=0.5, noise_shape=None, seed=None, training=False, name=None)
Applies Dropout to the input.
Dropout consists in randomly setting a fraction rate
of input units to 0 at each update during training time, which helps prevent overfitting. The units that are kept are scaled by 1 / (1 - rate)
, so that their sum is unchanged at training time and inference time.
inputs
: Tensor input.rate
: The dropout rate, between 0 and 1. E.g. "rate=0.1" would drop out 10% of input units.noise_shape
: 1D tensor of type int32
representing the shape of the binary dropout mask that will be multiplied with the input. For instance, if your inputs have shape (batch_size, timesteps, features)
, and you want the dropout mask to be the same for all timesteps, you can use noise_shape=[batch_size, 1, features]
.seed
: A Python integer. Used to create random seeds. See tf.set_random_seed
for behavior.training
: Either a Python boolean, or a TensorFlow boolean scalar tensor (e.g. a placeholder). Whether to return the output in training mode (apply dropout) or in inference mode (return the input untouched).name
: The name of the layer (string).Output tensor.
