tf.contrib.layers.dropout(*args, **kwargs)

tf.contrib.layers.dropout(*args, **kwargs)

Returns a dropout op applied to the input.

With probability keep_prob, outputs the input element scaled up by 1 / keep_prob, otherwise outputs 0. The scaling is so that the expected sum is unchanged.


  • inputs: the tensor to pass to the nn.dropout op.
  • keep_prob: A scalar Tensor with the same type as x. The probability that each element is kept.
  • noise_shape: A 1-D Tensor of type int32, representing the shape for randomly generated keep/drop flags.
  • is_training: A bool Tensor indicating whether or not the model is in training mode. If so, dropout is applied and values scaled. Otherwise, inputs is returned.
  • outputs_collections: collection to add the outputs.
  • scope: Optional scope for name_scope.


a tensor representing the output of the operation.
