Detailed Description

template<class T>
class prapi::EuclideanDistance< T >

The standard Euclidean distance as a proximity measure.


Public Methods

double getProximity (const util::List< T > &sample, const util::List< T > &model, double stopAfter=MAXDOUBLE) const throw (ProximityException&)
 Proximity between two lists.


Member Function Documentation

template<class T>
double prapi::EuclideanDistance< T >::getProximity const util::List< T > &    sample,
const util::List< T > &    model,
double    stopAfter = MAXDOUBLE
const throw (ProximityException&) [virtual]
 

Proximity between two lists.

Parameters:
sample  the list to be classified
model  the model
stopAfter  A value that can be used in optimizing the performance of a proximity measure. Classifiers may set this value to inform the proximity measure to stop if it notices the proximity will be over a certain value. For example, the kNN classifier sets this value to the kth smallest proximity so far. If a sample is not closer than that, then it makes no sense to inspect it any more.

Implements prapi::ProximityMeasure< T >.
