机器学习：K-近邻算法对鸢尾花数据进行分类预测

K-近邻算法 KNN定义：如果一个样本在特征空间中的k个最相似（即特征空间中最近邻）的样本中的大多数属于某一个类别，则改样本也属于这个类别计算距离：欧式距离z = sqrt((x1-x2)^2 + (y1-y2)^2)相似样本，特征之间的值应该都是相近的需要做标准化处理k的取值k较小容易受异常点....

怎么用python机器学习的KNN算法实现对鸢尾花数据集的分类？求详细代码

【人工智能】机器学习之Python使用KNN算法进行电影类型预测以及使用KNN算法对鸢尾花进行分类

1. 使用KNN进行电影类型预测：给定训练样本集合如下：求解：testData={"老友记": [29, 10, 2, "？片"]}。解题步骤： 1.计算一个新样本与数据集中所有数据的距离 2.按照距离大小进行递增排序 3.选取距离最小的k个样本 4.确定前k个样本所在类别出现的频率，并输出出现频...
