meaning of these methods, see machine learning textbook. One more useful function is train_test_split.function: Train data and test data are randomly selected from the sample. The invocation form is:X_train, X_test, y_train, y_test = Cross_validation.train_test_split (Train_data, Train_target, test_size=0.4, random_state=0)Test_size is a sample-to-account ratio. If it is an integer, it is the number of sam

statistical tests for each feature:false positive rate SELECTFPR, false discovery rate selectfdr, or family wise error selectfwe. The document says that if you use a sparse matrix, only the CHI2 indicator is available, and everything else must be transformed into the dense matrix. But I actually found that f_classif can also be used in sparse matrices.Recursive Feature elimination: Looping feature selectionInstead of examining the value of a variable individually, it aggregates it together for

4 seconds), LR very quickly (three classes of instance time is 2 seconds, 5 seconds, ~30 seconds), RF is not slow (one instance9 seconds, the other 26 seconds), linear kernel SVM is several times slower than LR (all instance to run more than 30 seconds), the RBF kernel SVM is slower than linear SVM 20+ Times to a hundredfold (the first instance to 11 minutes, the second instance ran for nearly two hours). Accuracy on RF>LR>DT>GNB>SVM (RBF kernel) >SVM (Linear kernel). GNB and SVM (linear kernel

In the use of VirtualBox and related client systems, such as XP,MAC, need to use some related functions, share the Clipboard and so on, at this time, need to install a tool in VirtualBox, called the guest additions, Chinese name is different: Enhanced toolkit, Enhancements to the package, enhanced feature packs, are all a means. Below, take the client as XP for example, explain in detail how to install the feature Enhancement Pack for VirtualBox: 1.

virtual operating system you need to install the appropriate driver.Finally, the virtual machine runs as follows:As you can see, the program provides an interface with a very rich menu of features that are very powerful and can even send combination keys to the operating system in the virtual machine.So to speak, if there is no VirtualBox, the QEMU+KVM combination should be the preferred choice for desktop users. Next I will try Virtualbox,virtualbox
