1.1 KNN的通俗解释 何谓K近邻算法,即K-Nearest Neighbor algorithm,简称KNN算法,单从名字来猜想,可以简单粗暴的认为是:K个最近的邻居,当K=1时,算法便成了最近邻算法,即寻找最近的那个邻居。 用官方的话来说,所谓K近邻算法,即是给定一个训练数据集,对新的输入实例,在训练数据集中找到与该实例最邻近的K个实例(...

This guide to the K-Nearest Neighbors (KNN) algorithm in machine learning provides the most recent insights and techniques.
The fast growth of wireless technology in today's scenario has paved huge demand for licenced and unlicenced frequencies of the spectrum. Cognitive radio will be useful for this issue as it provides better spectrum utilisation. This paper deals with the study of machine learning algorithm for ...
To solve the problems, in the paper we propose a privacy-preserving kNN query processing algorithm via secure two-party computation on the encrypted database. Our algorithm preserves both data privacy and query privacy while hid- ing data access patterns. For this, we propose efficient and ...
