static double |
calc_weighted_comp_sum(Comparator[] comparators,
double[] weights,
int[] originalIndices,
Node nodeX,
Node nodeY)
Returns weighted sum k of local comparators: k = sum(w_i * k_i) with:
k_i: local comparators w_i: local weights
Note: Comparators, weights, originalIndices are supposed to originate
from the same AlignmentSpecification.
|
<X extends Value,Y> |
calculateParameterDerivative(DerivableComparator<X,Y> comp)
This returns the derivatives for all parameters of the given comparator
according to the implementation.
|
<X extends Value,Y> |
calculateRawParameterDerivative(DerivableComparator<X,Y> comp)
This returns the derivatives for all parameters of the given comparator
according to the implementation.
|
double[] |
calculateWeightDerivative()
Calculates the derivative for each keyword weight.
|
double[][] |
getSimilarityMatrix()
This is the dynamic programming matrix calculated by a
DynamicTimeWarpingAlgorithm.
|
double |
getSimilarityScore()
Returns the softDTW score between the two input sequences.
|
AlignmentSpecification |
getSpecificaton()
Returns the AlignmentSpecification that was basis for this Alignment.
|
Sequence |
getX()
Returns the first input sequence.
|
Sequence |
getY()
Returns the second input sequence.
