如何使用java获取weka中最近的邻居 [英] How to get the nearest neighbor in weka using java

问题描述

我一直在尝试使用与weka机器学习库一起使用的Ibk最近邻算法。

I've been trying to use the Ibk nearest neighbor algorithm that goes together with the weka machine learning library.

我知道如何对实例进行分类，但我想要实现协同过滤功能，所以我需要实际获取最接近感兴趣对象的实际对象列表。

I know how to classify instances, but I want to implement the collaborative filtering feature so I need to actually get the list of actual objects that are nearest to the object of interest.

我将如何在weka中实际执行此操作它的Java API？

How would I actually do so in weka using its java API?

推荐答案

这个怎么样

weka.core.neighboursearch.LinearNNSearch knn = new LinearNNSearch(
            trainingInstances);
//do other stuff

Instances nearestInstances= knn.kNearestNeighbours(target, 3)

以下是 API文档你可以参考。
