Description Usage Arguments Details

View source: R/nnf-activation.R

Description

Applies element-wise, the function Softplus(x) = 1/β * log(1 + exp(β * x)).

Usage

1
nnf_softplus(input, beta = 1, threshold = 20)

Arguments

input

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

beta

the beta value for the Softplus formulation. Default: 1

threshold

values above this revert to a linear function. Default: 20

Details

For numerical stability the implementation reverts to the linear function when input * β > threshold.
