dataset = pandas .read_csv(url, names=names) dataset.hist() #数据直方图histograms 1. 2. 3. 4. 这里因为我们要借助pyspark读取数据,所以对下载csv格式的iris.data先进行下格式上的预处理: 将.data后缀修改为.text 用excel打开iris.text,删除最后一行并保存,中间会让选择间隔方式什么的,直接默认,出来的text...

首先, 在 Machine Learning Repository 下载 Iris Dataset, 在 pyspark框架下读取数据集内容并将读取数据转为 DataFrame 格式,读取数据的结果如下图所示。 通过设定不同的 k 值, 计算 K-means 聚类算法的聚类效果, 同时计算每次聚类结果下的聚类中心。 本实验设定 k 值为 2-9 之间的整数值。 在K-Means 算法的...
"Inspired" in this particular case means that we won't have all the data available, so the accuracy of our ML model could be better. In any case, if you are interested on using the whole dataset check outworkshop-integratedml-intro. ...
