ChebyshevDistance
Chebyshev Distance is the L∞ norm.
|
CosineDistance
The Cosine Distance is a adaption of the Cosine Similarity's range from
[-1, 1] into the range [0, 1].
|
CosineDistanceNormalized
This distance metric returns the same cosine distance as
CosineDistance . |
DenseSparseMetric
Many algorithms require computing the distances from a small set of points to
many other points.
|
DistanceCounter
This class exists primarily as a sanity/benchmarking utility.
|
DistanceMetric
A distance metric defines the distance between two points in a metric space.
|
EuclideanDistance
Euclidean Distance is the L2 norm.
|
KernelDistance
Creates a distance metric from a given kernel trick.
|
MahalanobisDistance
The Mahalanobis Distance is a metric that takes into account the variance of the data.
|
ManhattanDistance
Manhattan Distance is the L1 norm.
|
MinkowskiDistance
Minkowski Distance is the Lp norm.
|
NormalizedEuclideanDistance
Implementation of the Normalized Euclidean Distance Metric.
|
PearsonDistance
A valid distance metric formed from the Pearson Correlation between two vectors.
|
SquaredEuclideanDistance
In many applications, the squared
EuclideanDistance is used because it avoids an expensive Math.sqrt(double) operation. |
TrainableDistanceMetric
Some Distance Metrics require information that can be learned from the data set.
|
WeightedEuclideanDistance
Implements the weighted Euclidean distance such that d(a, b) =
∑∀ i ∈ |w| wi
(xi-yi)2
When used with a weight vector of ones, it degenerates into the EuclideanDistance . |
