The dataset will contain the inputs in the two-dimensional array x and outputs in the one-dimensional array y: Python >>> x = np.arange(1, 25).reshape(12, 2) >>> y = np.array([0, 1, 1, 0, 1, 0, 0, 1, 1, 0, 1, 0]) >>> x array([[ 1, 2], [ 3, 4], [...
In this example, the regular expression[:|-]specifies that Python should split the string at any occurrence of a colon, vertical bar, or minus sign. As you can see, there.split()function provides a concise way to handle cases that involve multiple delimiters. ...

random_split方法的原理是通过随机抽样的方式将数据集切分为指定长度的子集。该方法使用了Python标准库中的random模块。 下面是random_split方法的内部实现: defrandom_split(dataset,lengths):ifsum(lengths)!=len(dataset):raiseValueError("Sum of input lengths does not equal the length of the input dataset!")...
