Member Function Documentation

apply()

torch::Tensor iganet::Softplus::apply ( const torch::Tensor &  input ) const

inlineoverridevirtual

Applies the activation function to the given input.

Parameters

input

Tensor to which the activation function is applied.

Returns

The activated tensor.

Implements iganet::ActivationFunction.

options() [1/2]

torch::nn::functional::SoftplusFuncOptions & iganet::Softplus::options ( )

inline

Returns non-constant reference to options.

Returns

Mutable reference to the activation options.

options() [2/2]

const torch::nn::functional::SoftplusFuncOptions & iganet::Softplus::options ( ) const

inline

Returns constant reference to options.

Returns

Constant reference to the activation options.

pretty_print()

void iganet::Softplus::pretty_print ( std::ostream &  os ) const

inlineoverridevirtualnoexcept

Returns a string representation of the activation function.

Parameters

os	Stream that receives the representation.

Implements iganet::ActivationFunction.

read()

torch::serialize::InputArchive & iganet::Softplus::read ( torch::serialize::InputArchive &  archive, const std::string &  key = "softplus"  )
