特征更多的时候是分类特征，而不是连续的数值特征。 比如一个人的特征可以是``[“male”, “female”]``， ["from Europe", "from US", "from Asia"]， ["uses Firefox", "uses Chrome", "uses Safari", "uses Internet Explorer"]。 这样的特征可以高效的编码成整数，例如 ["male

DAT并不是一种标准文件。许多软件都使用这个扩展名，但文件含义不同。而许多数据分析软件也用这个扩展名保存数据。所以这要看具体的软件情况来定。DAT文件，可以按照扩展名来看就是DATA的意思，即数据文件，这类文件并没有进行绝对化的定义。dat文件批处理转为txt文件#utf-8import osimport syspath_0 =r"C:\Users\dell\Desktop\PAMAP2_...

matlab中使用的数据一般会以mat的格式存储，用python读取有以下几种方法1、使用scipy，具体实现如下：import scipy.io as scioimport pandas as pddata_path="train.mat"#Method 1data = scio.loadmat(data_path)data_train_label=data_train.get('label')
