smile.neighbor

Class Neighbor<K,V>

java.lang.Object

smile.neighbor.Neighbor<K,V>

Type Parameters:

K - the type of keys.

V - the type of associated objects.

All Implemented Interfaces:

java.lang.Comparable<Neighbor<K,V>>

Direct Known Subclasses:

SimpleNeighbor

public class Neighbor<K,V>
extends java.lang.Object
implements java.lang.Comparable<Neighbor<K,V>>

The object encapsulates the results of nearest neighbor search. A returned neighbor for nearest neighbor search contains the key of object (say weight vector of a neuron) and the object itself (say a neuron in neural network, which also contains other information beyond weight vector), an index of object in the dataset, which is often useful, and the distance between the query key to the object key.
