Hardtanh module

Usage

nn_hardtanh(min_val = -1, max_val = 1, inplace = FALSE)

Arguments

min_val

minimum value of the linear region range. Default: -1

max_val

maximum value of the linear region range. Default: 1

inplace

can optionally do the operation in-place. Default: FALSE

Details

$$\text{HardTanh}(x)=\{\begin{array}{ll}1& \text{ if }x>1\\ -1& \text{ if }x<-1\\ x& \text{ otherwise }\end{array}$$

The range of the linear region :math:[-1, 1] can be adjusted using min_val and max_val.

Shape

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

• Output: $(N,\ast )$, same shape as the input

Examples

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