nn_hardtanh: Hardtanh module

Description Usage Arguments Details Shape Examples

Description

Applies the HardTanh function element-wise HardTanh is defined as:

Usage

1
nn_hardtanh(min_val = -1, max_val = 1, inplace = FALSE)

Arguments

min_val

minimum value of the linear region range. Default: -1

max_val

maximum value of the linear region range. Default: 1

inplace

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

Details

\mbox{HardTanh}(x) = ≤ft\{ \begin{array}{ll} 1 & \mbox{ if } x > 1 \\ -1 & \mbox{ if } x < -1 \\ x & \mbox{ otherwise } \\ \end{array} \right.

The range of the linear region :math:[-1, 1] can be adjusted using min_val and max_val.
