ELU module

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

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

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_elu()
input <- torch_randn(2)
output <- m(input)
}
