nnf_elu {torch}

Elu

Description

Applies element-wise,

ELU(x) = max(0,x) + min(0, \alpha * (exp(x) - 1))

.

Usage

nnf_elu(input, alpha = 1, inplace = FALSE)

nnf_elu_(input, alpha = 1)

Arguments

input

(N,*) tensor, where * means, any number of additional dimensions

alpha

the alpha value for the ELU formulation. Default: 1.0

inplace

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

Examples

if (torch_is_installed()) {
x <- torch_randn(2, 2)
y <- nnf_elu(x, alpha = 1)
nnf_elu_(x, alpha = 1)
torch_equal(x, y)
}
