Package generic.lsh.vector

Class LSHCosineVectorAccum

java.lang.Object

generic.lsh.vector.LSHCosineVector

generic.lsh.vector.LSHCosineVectorAccum

All Implemented Interfaces:

LSHVector

public class LSHCosineVectorAccum
extends LSHCosineVector

A cosine vector where we can accumulate the (feature,weight) pairs over time using the addHash method. Once either the getLength or compare methods is called the vector becomes "finalized" and acts as an ordinary LSHCosineVector
