under-fitting with verification curveValidating a curve is a very useful tool that can be used to improve the performance of a model because he can handle fit and under-fit problems.The verification curve and the learning curve are very similar, but the difference is that the accuracy rate of the model under different parameters is not the same as the accuracy of the different training set size:We get the validation curve for parameter C.Like the Lea

, here is introduced 1vs (n–1) and 1v1. More SVM Multi-classification application introduction, reference ' SVM Multi-Class classification method 'In the previous method we need to train n classifiers, and the first classifier is to determine whether the new data belongs to the classification I or to its complement (except for the N-1 classification of i). The latter way we need to train N * (n–1)/2 classifiers, the classifier (I,J) is able to determine whether a point belongs to I or J, and whe

training dataset, you can test the model with a test data set, predict the performance of the model on unknown data, and evaluate the generalization error of the model. If we are satisfied with the evaluation results of the model, we can use this model to predict future new unknown data. It is important to note that the parameters required in the previous steps of feature scaling, dimensionality reduction, etc., can only be obtained from the training data set and can be applied to test datasets
