- All Known Implementing Classes:
public interface WeightFunctionWeightFunction interface that allows the use of various distance-based weight functions. In addition to the distance parameter, the maximum distance and standard deviation are also given, to allow distance functions to be normalized according to the maximum or standard deviation.
- Erich Schubert
double getWeight(double distance, double max, double stddev)Evaluate weight function with given parameters.
Note that usually implementations will ignore either max or stddev.
distance- distance of the query point
max- maximum distance of all included points
stddev- standard deviation (i.e. quadratic mean / RMS) of the included points
- weight for the query point
