torch_log1p {torch}

Log1p

Description

Log1p

Usage

torch_log1p(self)

Arguments

self

(Tensor) the input tensor.

log1p(input, out=NULL) -> Tensor

Returns a new tensor with the natural logarithm of (1 + input).

y_i = \log_{e} (x_i + 1)

Note

This function is more accurate than torch_log for small values of input

Examples

if (torch_is_installed()) {

a = torch_randn(c(5))
a
torch_log1p(a)
}
