mlr_pipeops_nn_dropout {mlr3torch}

Dropout

Description

During training, randomly zeroes some of the elements of the input tensor with probability p using samples from a Bernoulli distribution.

Input and Output Channels

One input channel called "input" and one output channel called "output". For an explanation see PipeOpTorch.

State

The state is the value calculated by the public method ⁠$shapes_out()⁠.

Parameters

• p :: numeric(1)
  Probability of an element to be zeroed. Default: 0.5 inplace

• inplace :: logical(1)
  If set to TRUE, will do this operation in-place. Default: FALSE.

Internals

Calls torch::nn_dropout() when trained.
