成员函数说明

virtual SGVector<float64_t> get_dual_variable ( SGVector< float64_t >  variable )

pure virtual

Get dual variable

参数

variable

primal variable

返回

dual variable

在 PNormMappingFunction 内被实现.

virtual void load_from_context ( CMinimizerContext *  context )

pure virtual

Load the given context object to restore mutable variables

This method will be called by SMDMinimizer::load_from_context(CMinimizerContext* context)

参数

context

a context object

在 PNormMappingFunction 内被实现.

virtual void update_context ( CMinimizerContext *  context )

pure virtual

Update a context object to store mutable variables used in learning rate

This method will be called by SMDMinimizer::update_context()

参数

context

a context object

在 PNormMappingFunction 内被实现.

virtual void update_variable ( SGVector< float64_t >  variable, SGVector< float64_t >  dual_variable  )

pure virtual

Update primal variable in place given dual variable

参数

variable	primal variable to be updated
dual_variable	dual variable are known

在 PNormMappingFunction 内被实现.
