OPTICS family of clustering algorithms.
Note that some OPTICS based algorithms (HiCO, DiSH) are in the subspace and correlation packages, which better describes their use case.
Interface Summary Interface Description GeneralizedOPTICSA trivial generalization of OPTICS that is not restricted to numerical distances, and serves as a base for several other algorithms (HiCO, HiSC). OPTICSTypeAlgorithmInterface for OPTICS type algorithms, that can be analyzed by OPTICS Xi etc.
Class Summary Class Description AbstractOPTICS<O>The OPTICS algorithm for density-based hierarchical clustering. ClusterOrderClass to store the result of an ordering clustering algorithm such as OPTICS. CorrelationClusterOrderCluster order entry for correlation-based OPTICS variants. DeLiClu<V extends NumberVector>DeliClu: Density-Based Hierarchical Clustering DeLiClu.Par<V extends NumberVector>Parameterization class. DeLiClu.SpatialObjectPairEncapsulates an entry in the cluster order. FastOPTICS<V extends NumberVector>FastOPTICS algorithm (Fast approximation of OPTICS) GeneralizedOPTICS.Instance<R>Instance for processing a single data set. OPTICSHeap<O>The OPTICS algorithm for density-based hierarchical clustering. OPTICSHeap.Par<O>Parameterization class. OPTICSHeapEntryEntry in the priority heap. OPTICSList<O>The OPTICS algorithm for density-based hierarchical clustering. OPTICSList.Par<O>Parameterization class. OPTICSXiExtract clusters from OPTICS plots using the original ξ (Xi) extraction, which defines steep areas if the reachability drops below 1-ξ, respectively increases to 1+ξ, of the current value, then constructs valleys that begin with a steep down, and end with a matching steep up area. OPTICSXi.ClusterHierarchyBuilderClass to build the hierarchical clustering result structure. OPTICSXi.ParParameterization class. OPTICSXi.SteepAreaData structure to represent a steep-down-area for the xi method. OPTICSXi.SteepAreaResultResult containing the xi-steep areas. OPTICSXi.SteepDownAreaData structure to represent a steep-down-area for the xi method. OPTICSXi.SteepScanPositionPosition when scanning for steep areas OPTICSXi.SteepUpAreaData structure to represent a steep-down-area for the xi method.
