The DistancePowerDistance type exposes the following members.
Constructors Properties | Name | Description |
---|
| Function |
Returns a Distance.Function delegate that encapsulates
this.GetDistance.
|
| P |
Gets and sets the power for the power distance calculation.
|
| R |
Gets and sets the root for the power distance calculation.
|
TopMethods | Name | Description |
---|
| Clone |
Creates a deep copy of this PowerDistance.
|
| GetDistance |
Returns the power distance between two data sets, using the current
values of parameters p and r.
|
TopRemarks
The power distance is computed as:
distance( x, y ) = ( |xi - yi|^p )^1/r
where
p and
r are user-defined parameters. Parameter
p
controls the progressive weight that is placed on differences on individual
dimensions; parameter
r controls the progressive weight that is placed
on larger differences between objects. Appropriate selections of
p and
r yield Euclidean, squared Euclidean, Minkowski, city-block, and many
other distance metrics. For example, if
p and
r are equal to 2,
the power distance is equal to the Euclidean distance.
Property
DistanceDelegate returns a
Distance.Function
delegate that encapsulates
this.GetDistance. The returned delegate can be
used by an instance of class ClusterAnalysis for computing the distances between
objects during cluster analysis using the power distance metric.
