网格搜索 GridSearchCV我们在选择超参数有两个途径:1凭经验;2选择不同大小的参数,带入到模型中,挑选表现最好的参数。通过途径2选择超参数时,人力手动调节注意力成本太高,非常不值得。For循环或类似于for循环的方法受限于太过分明的层次,不够简洁与灵活,注意力成本高,易出错。GridSearchCV 称为网格搜索交叉验证调参...
For Loops using Sequential Data Types Listsand other data sequence types can also be leveraged as iteration parameters inforloops. Rather than iterating through arange(), you can define a list and iterate through that list. We’ll assign a list to a variable, and then iterate through the lis...
