Class DefaultVectorCollectionFactory<V extends Vec>

java.lang.Object

jsat.linear.vectorcollection.DefaultVectorCollectionFactory<V>

All Implemented Interfaces:

Serializable, Cloneable, VectorCollectionFactory<V>

public class DefaultVectorCollectionFactory<V extends Vec>
extends Object
implements VectorCollectionFactory<V>

DefaultVectorCollectionFactory is a generic factory that attempts to return a good vector collection for the given input. It may take into account the size of the data set, dimensions, and the distance metric in use to select a Vector Collection that will have the highest overall performance.
