ELU module

Applies the element-wise function:

Usage

nn_elu(alpha = 1, inplace = FALSE)

Arguments

alpha

the \(\alpha\) value for the ELU formulation. Default: 1.0

inplace

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

Details

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

Shape

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

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

Examples

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