KNNWeightProcessor (ELKI: Environment for DeveLoping KDD-Applications Supported by Index-Structures)

java.lang.Object
- elki.parallel.processor.AbstractDoubleProcessor
- - elki.outlier.distance.parallel.KNNWeightProcessor

All Implemented Interfaces:

Processor
```
public class KNNWeightProcessor
extends AbstractDoubleProcessor
```
Compute the kNN weight score, used by ParallelKNNWeightOutlier. Needs the k nearest neighbors as input, for example from KNNProcessor

Since:

0.7.0
