Interface SegmentedModel

All Superinterfaces:

Model, QuickSerializable

All Known Implementing Classes:

HMM, SemanticDistanceModel

public interface SegmentedModel

extends Model

An interface for introspective models which participate as part of large, distributed models. In addition to normal Model functionality, SegmentedModels understand how to swap tagged portions of the model state (Segments) from a foreign distributor.
