double |
compare(SymbolicValue a,
SymbolicValue b)
This has to return a distance between a and b with the following
restrictions:
The return value has to lie between 0 and 1.
|
double |
comparisonDerivative(int paramIdx,
SymbolicValue a,
SymbolicValue b)
This should implement the local derivative calculation in case of
comparisons.
|
double |
getMatchCost() |
double |
getMismatchCost() |
int |
getNumberOfComparisonParameters()
Implementing classes should return the number of (derivative-relevant)
parameters used for the compare-function.

SparseLocalDerivative |
sparseComparisonDerivative(SymbolicValue a,
SymbolicValue b)
This should implement the local derivative calculation in case of
comparisons.
