Detailed Description

template<typename Scalar>
class ldaplusplus::em::SemiSupervisedEStep< Scalar >

SemiSupervisedEStep passes a document to either a supervised step or an unsupervised step based on whether there exists class information for a given document.

SemiSupervisedEStep emits all the events emitted from the supervised or unsupervised expectation steps so one has to subscribe only to the SemiSupervisedEStep and not the steps passed in as constructor parameters.

Constructor & Destructor Documentation

template<typename Scalar >

ldaplusplus::SemiSupervisedEStep::SemiSupervisedEStep	(	std::shared_ptr< EStepInterface< Scalar > >	supervised_step,
		std::shared_ptr< EStepInterface< Scalar > >	unsupervised_step
	)

Parameters

supervised_step	A pointer to a supervised expectation step
unsupervised_step	A pointer to an unsupervised expectation step
