Enum engram::activation::Activation

pub enum Activation {
    Sigmoid,
    TanH,
    ReLU,
    LeakyReLU,
}

An activation function.

Variants

Sigmoid

TanH

ReLU

LeakyReLU

Implementations

impl Activation

pub fn apply(&self, x: f64) -> f64

Returns the result of the activation function.

Examples

Activation::Sigmoid.apply(1.0);

pub fn grad(&self, x: f64) -> f64

Returns the derivative of the activation function.

Examples

Activation::ReLU.grad(1.0);

Trait Implementations

impl Clone for Activation

fn clone(&self) -> Activation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Activation

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for Activation

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Activation

fn eq(&self, other: &Activation) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
