The Dropout layer randomly sets input units to 0 with a frequency of
rate at each step during training time, which helps prevent overfitting.
Inputs not set to 0 are scaled up by 1 / (1 - rate) such that the sum over
all inputs is unchanged.
Note that the Dropout layer only applies when training is set to TRUE
in call(), such that no values are dropped during inference.
When using model.fit, training will be appropriately set to TRUE
automatically. In other contexts, you can set the argument explicitly
to TRUE when calling the layer.
(This is in contrast to setting trainable=FALSE for a Dropout layer.
trainable does not affect the layer's behavior, as Dropout does
not have any variables/weights that can be frozen during training.)
layer_dropout(object, rate, noise_shape = NULL, seed = NULL, ...)The return value depends on the value provided for the first argument.
If object is:
a keras_model_sequential(), then the layer is added to the sequential model
(which is modified in place). To enable piping, the sequential model is also
returned, invisibly.
a keras_input(), then the output tensor from calling layer(input) is returned.
NULL or missing, then a Layer instance is returned.
Object to compose the layer with. A tensor, array, or sequential model.
Float between 0 and 1. Fraction of the input units to drop.
1D integer tensor 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).
An R integer to use as random seed.
For forward/backward compatability.
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).
