RSquaredTInstance Class | |
Implements an internal evaluation method measuring the complement of the ratio of the sum of squared distances
between elements in different clusters to the total sum of squares. This criterion considers only the separation
between the clusters given some partition scheme (ClusterSetTInstance).
Inheritance HierarchyNamespace: Aglomera.Evaluation.Internal
Assembly: Aglomera (in Aglomera.dll) Version: 1.1.0
SyntaxC#
public class RSquared<TInstance> : IInternalEvaluationCriterion<TInstance> where TInstance : Object, IComparable<TInstance>
Type Parameters
- TInstance
- The type of instance considered.
The RSquaredTInstance type exposes the following members.
Constructors| Name | Description | |

 | RSquaredTInstance |

Methods| Name | Description | |

Remarks
In order to select the optimal partition / ClusterSetTInstance using this criterion given
some ClusteringResultTInstance one has to find the 'knee' in the plot of the criterion value vs.
the number of clusters.
