Dropout: Applies Dropout to the input.

In YTLogos/kerasR: R Interface to the Keras Deep Learning Library

Description

Applies Dropout to the input.

Usage

Dropout(rate, noise_shape = NULL, seed = NULL, input_shape = NULL)

Arguments

rate	float between 0 and 1. Fraction of the input units to drop.
noise_shape	1D integer tensor representing the shape of the the input.
seed	A Python integer to use as random seed.
input_shape	only need when first layer of a model; sets the input shape of the data
