Variants

Identity

Identity: ƒ(x) = x

BinaryStep

Binary Step: ƒ(x) = 0 if x < 0 ƒ(x) = 1 if x ≥ 0

Logistic

Logistic function

Tanh

Tangens Hyperbolicus (tanh): ƒ(x) = tanh(x)

ArcTan

Arcus Tangens (atan): ƒ(x) = atan(x)

SoftSign

Soft Sign: ƒ(x) = x ⋅ (1 + |x|)⁻¹

ReLU

ReLU: ƒ(x) = 0 if x < 0 ƒ(x) = x else

SoftPlus

Soft Plus: ƒ(x) = ln(1 + eˣ)

BentIdentity

Bent Identity: ƒ(x) = ½(sqrt(x² + 1) - 1) + x

Sinusoid

Sinusoid: ƒ(x) = sin(x)

Gaussian

Gaussian: ƒ(x) = e⁻ˣˣ

Methods

impl Activation

fn base<F: NdFloat>(self, x: F) -> F

Returns f(x) with a given x and f as the base function.

fn derived<F: NdFloat>(self, x: F) -> F

Returns dx(x) with a given x and dx as the derived function.

Trait Implementations

Formats the value using the given formatter.

impl Copy for Activation

impl Clone for Activation

fn clone(&self) -> Activation

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)
