Trait ActivatorGradient 

pub trait ActivatorGradient<T> {
    type Rel: Activator<T>;
    type Delta;

    // Required method
    fn activate_gradient(&self, input: T) -> Self::Delta;
}

The ActivatorGradient trait extends the Activator trait to include a method for computing the gradient of the activation function.

Required Associated Types

type Rel: Activator<T>

type Delta

Required Methods

fn activate_gradient(&self, input: T) -> Self::Delta

compute the gradient of some input

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
