一共40分钟 1道coding 10道选择题,根据我的回忆可能将题目合并
[hidee=100]coding: Given a integer N in [-8000,8000] . Return a maximum integer after insert 5.
选择题:
1. which metric is not for classification/regression performance
AIC, log loss, hamming distance, RSE, cook distance, mattew coefficient correlation, lift curve, maxiumum depth of trees.
6. At which situation, k-fold cross validation is useless?
A. demension reduction of PCA B. number of K clusters 这道题有点奇怪,这两个选项我觉得都可以,可惜单选,我选了A。
7. Difference between accuracy pecision and recall.[/hide]
