nn_hardshrink {torch}

Hardshwink module

Description

Applies the hard shrinkage function element-wise:

Usage

nn_hardshrink(lambd = 0.5)

Arguments

lambd

the \lambda value for the Hardshrink formulation. Default: 0.5

Details

\mbox{HardShrink}(x) = \left\{ \begin{array}{ll} x, & \mbox{ if } x > \lambda \\ x, & \mbox{ if } x < -\lambda \\ 0, & \mbox{ otherwise } \end{array} \right.

Shape

• Input: (N, *) where * means, any number of additional dimensions

• Output: (N, *), same shape as the input

Examples

if (torch_is_installed()) {
m <- nn_hardshrink()
input <- torch_randn(2)
output <- m(input)
}
