Struct SoftShrink 

pub struct SoftShrink {
    pub lambda: f64,
}

Soft Shrink layer.

Applies the Soft Shrink function element-wise: soft_shrink(x) = x - lambda if x > lambda, x + lambda if x < -lambda, 0 otherwise

Should be created with SoftShrinkConfig.

Fields

lambda: f64

The lambda value for the Soft Shrink formulation.
