DATA- The input data type. This delta function works with a double, but can extract/convert to it from any other given object in case the respective extractor has been set. See
ExtractionAwareDeltaFunctionfor more information.
@PublicEvolving public class CosineDistance<DATA> extends ExtractionAwareDeltaFunction<DATA,double>
|Constructor and Description|
|Modifier and Type||Method and Description|
This method is exactly the same as
public double getNestedDelta(double oldDataPoint, double newDataPoint)
DeltaFunction.getDelta(Object, Object)except that it gets the result of the previously done extractions as input. Therefore, this method only does the actual calculation of the delta but no data extraction or conversion.
