Member Function Documentation

virtual bool lti::MLP::activationFunctor::apply	(	const dvector &	src,
		dvector &	output
	)			const [pure virtual]

the functor operator.

Operates on copy

Implemented in lti::MLP::linearActFunctor, lti::MLP::signFunctor, and lti::MLP::sigmoidFunctor.

virtual bool lti::MLP::activationFunctor::apply

(

dvector &

output

)

const [pure virtual]

the functor operator.

Operates on place, applying the function to each element of the vector

Implemented in lti::MLP::linearActFunctor, lti::MLP::signFunctor, and lti::MLP::sigmoidFunctor.

virtual activationFunctor* lti::MLP::activationFunctor::clone

(

)

const [pure virtual]

return a copy of this functor

Implemented in lti::MLP::linearActFunctor, lti::MLP::signFunctor, and lti::MLP::sigmoidFunctor.

virtual bool lti::MLP::activationFunctor::deriv

(

dvector &

output

)

const [pure virtual]

the derivative of the functor

Implemented in lti::MLP::linearActFunctor, lti::MLP::signFunctor, and lti::MLP::sigmoidFunctor.

virtual const double& lti::MLP::activationFunctor::offValue

(

)

const [pure virtual]

return value used to represent "false" or "off"

Implemented in lti::MLP::linearActFunctor, lti::MLP::signFunctor, and lti::MLP::sigmoidFunctor.

virtual const double& lti::MLP::activationFunctor::onValue

(

)

const [pure virtual]

return value used to represent "true" or "on"

Implemented in lti::MLP::linearActFunctor, lti::MLP::signFunctor, and lti::MLP::sigmoidFunctor.

virtual bool lti::MLP::activationFunctor::read	(	ioHandler &	handler,
		const bool	complete = true
	)			[inline, virtual]

read the parameters from the given ioHandler

Parameters:

	handler	the ioHandler to be used
	complete	if true (the default) the enclosing begin/end will be also written, otherwise only the data block will be written.

Returns:

true if write was successful

Reimplemented in lti::MLP::sigmoidFunctor.

References lti::ioHandler::readBegin(), and lti::ioHandler::readEnd().

virtual bool lti::MLP::activationFunctor::write	(	ioHandler &	handler,
		const bool	complete = true
	)			const [inline, virtual]

write the parameters in the given ioHandler

Parameters:

	handler	the ioHandler to be used
	complete	if true (the default) the enclosing begin/end will be also written, otherwise only the data block will be written.

Returns:

true if write was successful

Reimplemented in lti::MLP::sigmoidFunctor.
