Inheritance diagram for dismec::init::SubsetFeatureMeanInitializer:

Public Member Functions
	SubsetFeatureMeanInitializer (std::shared_ptr< const DatasetBase > data, const DenseRealVector &mean_of_all, std::shared_ptr< const GenericFeatureMatrix > local_features, real_t pos, real_t neg)

Public Member Functions inherited from dismec::init::WeightsInitializer
virtual	~WeightsInitializer ()=default

virtual void	get_initial_weight (label_id_t label_id, Eigen::Ref< DenseRealVector > target, objective::Objective &objective)=0
	Generate an initial vector for the given label. The result should be placed in target. More...

Public Member Functions inherited from dismec::stats::Tracked
	Tracked ()
	Default constructor, creates the internal `stats::StatisticsCollection`. More...

void	register_stat (const std::string &name, std::unique_ptr< Statistics > stat)
	Registers a tracker for the statistics `name`. More...

std::shared_ptr< StatisticsCollection >	get_stats () const
	Gets an ownership-sharing reference to the `StatisticsCollection`. More...

Protected Member Functions
std::pair< real_t, real_t >	calculate_factors (label_id_t label_id, const Eigen::Ref< DenseRealVector > &mean_of_positives)

Protected Member Functions inherited from dismec::stats::Tracked
	~Tracked ()
	Non-virtual destructor. Declared protected, so we don't accidentally try to do a polymorphic delete. More...

template<class T >
void	record (stat_id_t stat, T &&value)
	Record statistics. This function just forwards all its arguments to the internal `StatisticsCollection`. More...

void	declare_stat (stat_id_t index, StatisticMetaData meta)
	Declares a new statistics. This function just forwards all its arguments to the internal `StatisticsCollection`. More...

void	declare_tag (tag_id_t index, std::string name)
	Declares a new tag. This function just forwards all its arguments to the internal `StatisticsCollection`. More...

template<class... Args>
void	set_tag (tag_id_t tag, long value)
	Set value of tag. This function just forwards all its arguments to the internal `StatisticsCollection`. More...

template<class... Args>
auto	make_timer (stat_id_t id, Args... args)
	Creates a new `ScopeTimer` using `stats::record_scope_time`. More...
