Interface RelativeBetter

All Known Implementing Classes:

RelativeBetter.ErrorHardRatio, RelativeBetter.ErrorHardRatioSq, RelativeBetter.MaximizeSoftRatio

public interface RelativeBetter

Used to compare how much better a metric A is than metric B. If A is not better then 0.0 is returned.

Nested Class Summary

Nested Classes

Modifier and Type	Interface	Description
static class	RelativeBetter.ErrorHardRatio	Compares error metrics (0.0 = best, larger is worse) with a hard minimum in the value of B to dampen noise for small values and avoid divide by zero errors.
static class	RelativeBetter.ErrorHardRatioSq	Same as RelativeBetter.ErrorHardRatio but it assumes the input has been squared
static class	RelativeBetter.MaximizeSoftRatio	Computes a ratio where the values are being maximized.

Method Summary

Modifier and Type	Method	Description
double	computeBetterValue(double valueA, double valueB)	Computes how good valueA is relative to valueB.

Method Details

computeBetterValue

double computeBetterValue(double valueA,
 double valueB)

Computes how good valueA is relative to valueB. If equal or N is better than 0.0 is returned. Otherwise a positive value is returned.

Parameters:

valueA - Goodness value for A

valueB - Goodness value for B

Returns:

goodness ratio of A over B
