ClikaRT::ops::softshrink

function

softshrink()

Tensor softshrink(Tensor x, double lambd = 0.5)

Soft thresholding: shrinks every element toward zero by lambd.

$$\mathrm{softshrink}(x) = \mathrm{sign}(x)\cdot\max(|x| - \lambda,\; 0)$$

Parameters

• x: the input tensor.
• lambd: the shrink amount (lambda). Default 0.5.

Throws

• ClikaRT::Error: when the input's dtype is not served for this operation (the machine-readable reason rides code_name()).

Returns: a new tensor, same shape and dtype as x.

auto y = ClikaRT::ops::softshrink(x, 0.1);
