Detailed Description

Abstract base for activation functions applied to a neural field.

Subclasses implement operator() to transform an activation vector element-wise into an output (field "output" component).

Member Function Documentation

apply()

virtual void dnf_composer::element::ActivationFunction::apply ( const std::vector< double > &  input, std::vector< double > &  out  ) const

pure virtual

Apply the activation function in-place into a pre-allocated out buffer. out must already be sized to input.size(). No heap allocation occurs.

Implemented in dnf_composer::element::SigmoidFunction, dnf_composer::element::HeavisideFunction, and dnf_composer::element::AbsSigmoidFunction.

clone()

virtual std::unique_ptr< ActivationFunction > dnf_composer::element::ActivationFunction::clone ( ) const

pure virtual

Implemented in dnf_composer::element::SigmoidFunction, dnf_composer::element::HeavisideFunction, and dnf_composer::element::AbsSigmoidFunction.

operator()()

virtual std::vector< double > dnf_composer::element::ActivationFunction::operator() ( const std::vector< double > &  input )

pure virtual

Apply the activation function to input and return the result.

Implemented in dnf_composer::element::SigmoidFunction, dnf_composer::element::HeavisideFunction, and dnf_composer::element::AbsSigmoidFunction.

operator=()

ActivationFunction & dnf_composer::element::ActivationFunction::operator= ( const ActivationFunction &  )

delete

print()

virtual void dnf_composer::element::ActivationFunction::print ( ) const

pure virtual

Implemented in dnf_composer::element::SigmoidFunction, dnf_composer::element::HeavisideFunction, and dnf_composer::element::AbsSigmoidFunction.

toString()

virtual std::string dnf_composer::element::ActivationFunction::toString ( ) const

pure virtual

Implemented in dnf_composer::element::SigmoidFunction, dnf_composer::element::HeavisideFunction, and dnf_composer::element::AbsSigmoidFunction.
