I am using one-vs-rest SVM modeling with sklearn.svm.SVC. I want to know whether my model is over-fitting. For train set accuracy is 100% and for test set its 97%+. To analyze the model, I did the following: I plotted probability (using predict_proba(), that works as expalined...

代码在网上可以找到,savemodel.c与loadmodel.c 我把网上的引用放在下面 最近一直在用matlab和libsvm,发现libsvm库用起来还是很方便的,就是没有模型直接保存到文件和读取模型的matlab接口(C++的接口有)。由于有会用的Opencv等C/C++库,所以数据交换比较麻烦。看了一下libsvm的svm.h、svm.cpp文件,发现有svm_save_...
public SVMModel::__construct(string $filename = ?) Build a new SVMModel. Models will usually be created from the SVM::train function, but then saved models may be restored directly. Parameters ¶ filename The filename for the saved model file this model should load. Errors...
to overfit this data. Adjusted propensities attempt to compensate by evaluating model performance against a test or validation partition. This option requires that a partition field be defined in the stream and adjusted propensity scores be enabled in the modeling node before generating the model. ...
回归model = svmtrain(train_label, train_data, '-s 3 -t 2 -c 2.2 -g 2.8 -p 0.01'); 其中: train_label表示训练集的标签。 train_matrix表示训练集的数据。 libsvm_options是需要设置的一系列参数,如果用回归的话,其中的-s参数值应为3。
