Applies element-wise, $$ELU(x) = max(0,x) + min(0, \alpha * (exp(x) - 1))$$.
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)
}
