tf.compat.v1.nn.dropout

 
tf.nn.dropout(
    x, keep_prob=None, noise_shape=None, seed=None, name=None, rate=None
)

For each element of x, with probability rate, outputs 0, and otherwise scales up the input by 1 / (1-rate). The scaling is such that the expected sum is unchanged.

By default, each element is kept or dropped independently. If noise_shape is specified, it must be broadcastable to the shape of x, and only dimensions with noise_shape[i] == shape(x)[i] will make independent decisions. For example, if shape(x) = [k, l, m, n] and noise_shape = [k, 1, 1, n], each batch and channel component will be kept independently and each row and column will be kept or not kept together.

x A floating point tensor.
keep_prob (deprecated) A deprecated alias for (1-rate).
noise_shape A 1-D Tensor of type int32, representing the shape for randomly generated keep/drop flags.
seed A Python integer. Used to create random seeds. See tf.compat.v1.set_random_seed for behavior.
name A name for this operation (optional).
rate A scalar Tensor with the same type as x. The probability that each element of x is discarded.

A Tensor of the same shape of x.

ValueError If rate is not in [0, 1) or if x is not a floating point tensor.
