DSC: Data Stream Clusterer Base Classes

Description

Abstract base classes for all DSC (Data Stream Clusterer) and DSC_R classes. Concrete implementations can be found in the registry DSC_registry (See Examples Section).

Details

The DSC and DSC_R classes cannot be instantiated (calling DSC() or DSC_R() produces errors), but they serve as a base class from which other DSC classes inherit. Implementations can be found using the DSC registry DSC_registry (See Examples section).

Class DSC provides several generic functions that can operate on all DSC subclasses: print(), plot(), nclusters() to get the current number of clusters, get_centers() to get the cluster centers, and get_weights() to get the cluster weights (if implemented). get_centers() and get_weights() are typically overwritten by subclasses of DSC. DSC_R provides these functions for R-based DSC implementations.

Since DSC objects often contain external pointers, regular saving and reading operations will fail. Use saveDSC() and readDSC() which will serialize the objects first appropriately.
