Member Function Documentation

template<typename T >

T spams::FISTA::GraphPathL0< T >::eval ( const Vector< T > & x ) const

Here is the call graph for this function:

template<typename T >

T spams::FISTA::GraphPathL0< T >::eval_paths	(	const Vector< T > &	x,
		SpMatrix< T > &	paths_mat
	)		const

inlinevirtual

Reimplemented from spams::FISTA::Regularizer< T >.

References spams::SpMatrix< T >::n(), and spams::Vector< T >::rawX().

Here is the call graph for this function:

template<typename T >

void spams::FISTA::GraphPathL0< T >::fenchel	(	const Vector< T > &	input,
		T &	val,
		T &	scal
	)		const

inlinevirtual

returns phi^star( input ) and ouput=input if the fenchel is unconstrained returns 0 and scale input such that phi^star(output)=0 otherwise
