Solution 1: Quay-square test good for small dataset Solution 2: Boostrap test good for large dataset Fisher exactly test Machine Learning Model What is the fundamental idea behind Support Vector Machine? maximum margin 最优化问题 -> Omega -> 对偶 -> KKT 尽可能降低误差 hinge loss, balance, tradeoff non-linear的话，需要加入 kernel function 复变函数中将一个空间转移到另外一个空间 kernel function会把原空间中的内积，映射到新空间中的内积。使得原空间中的线性分类器，映射为新空间中的非线性分类器。 找kernel没有什么好办法， RBF polynomil What is the Random Forrest, AdBoost and GBDT?...
