Improve Your Model Performance using Cross Validation (in Python / R)
This article was originally published on November 18, 2015 and updated on April 30, 2018. One of the most interesting and challenging things about hackathons is getting a high score on both public and private leaderboards. I have closely monitored the series of Data Hackathons and found an interesting trend. This trend is based on participant rankings on the public and private leaderboards. One thing that stood out was that participants who rank higher on the public leaderboard lose their position after their ranks gets validated on the private leaderboard.

規則化和模型選擇(Regularization and model selection)——機器學習:交叉驗證Cross validation
零 問題提出 在機器學習中的偏差與方差一文中提到了偏差與方差。那麼在多種預測模型,如線性迴歸(y=θTx),多項式迴歸(y=θTx^(1~m))等,應使用那種模型才能達到偏差與方差的平衡最優? 形式化定義:假設可選的模型集合是M={M1,M2,...,Md},比如SVM,
