fl::KMeansParallel Class Reference

#include <cluster.h>

Inheritance diagram for fl::KMeansParallel:

List of all members.

Public Types
enum	EMstate { initializing, estimating, maximizing, checking }
Public Methods
	KMeansParallel (float maxSize, float minSize, int initialK, int maxK, const std::string &clusterFileName="")
	KMeansParallel (std::istream &stream, const std::string &clusterFileName="")
virtual void	run (const std::vector< Vector< float > > &data)
	Peform clustering on collection of points.
void	client (std::string serverName)
Static Public Methods
void *	listenThread (void *arg)
void *	proxyThread (void *arg)
Public Attributes
int	iteration
const std::vector< Vector< float > > *	data
Matrix< float >	member
float	largestChange
EMstate	state
pthread_mutex_t	stateLock
	Used for all access to shared structures.
std::vector< int >	workUnits
	List of current tasks, identified only by ints. Basically, these are positions in a well-defined loop.
int	unitsPending
	Number of workUnits still being worked on. Allows for error recovery by monitoring completion as a separate concept from tasks claimed by a thread.
