Enum Activation

#[non_exhaustive]
pub enum Activation<B>
where
    B: Backend,
{
    Gelu(Gelu),

Activation Layer Wrapper.

Provides support for many in-built burn::nn activations.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Gelu(Gelu)

Gelu activation layer.

PRelu(PRelu<B>)

PRelu activation layer.

Relu(Relu)

Relu activation layer.

LeakyRelu(LeakyRelu)

LeakyRelu activation layer.

SwiGlu(SwiGlu<B>)

SwiGlu activation layer.

Sigmoid(Sigmoid)

Sigmoid activation layer.

Tanh(Tanh)

Tanh activation layer.

HardSigmoid(HardSigmoid)

HardSigmoid activation layer.
