minimizing the degree of impurity at each step, the cart can handle the outliers and be able to handle the vacancy values. The termination condition of the tree partition: 1, the node achieves the complete purity; 2, the depth of the tree reaches the depth of the user3, the number of samples in the node belongs to the user specified number;Pruning method of tree is a pruning method of cost complexity;See details: http://blog.csdn.net/tianguokaka/article/details/9018933 Copyright NOTICE: This ar

training samples.The above two or three can be done in the case of inverse existence, but what if the characteristics of the data are more than the sample points, because the inverse is not present at this time? You can use the ridge regression method to solve this problem, that is, it will be converted to, the other and the previous approach is similar.Of course, there is a method called forward stepwise regression, it is through each step to a certain weight increase or decrease a small value
