KDD Travel time 排名28/3574的解决方案

共享一下自己的代码, 主要用了grid search 5 folds CV + 1 fold eval set,因为到了>后期cv grid search出来的参数也出现overfit了。所以第6 fold的cv没有参与最优的搜索,这是作为eval作用。最终排名28/3574,一个人的写的程序,作为参考。

KDD travel time competition rank 28/3574 solution

Share my code here. Basically I have used 5-fold cv grid search. Finally I got over-fitting , so I added one more fold for evaluation (not for grid search). At the end, I got a rank of 28/3574. Single person work. Hope it would be useful for you.
