chapter 14 support vector machines | hands-on machine

Chapter 14 Support Vector Machines. Support vector machines (SVMs) offer a direct approach to binary classification: try to find a hyperplane in some feature space that “best” separates the two classes. In practice, however, it is difficult (if not impossible) to find a hyperplane to perfectly separate the classes using just the original features

Jul 31, 2020 · The most used model evaluation scheme for classifiers is the 10-fold cross-validation procedure. The k-fold cross-validation procedure involves splitting the training dataset into k folds. The first k-1 folds are used to train a model, and the holdout kth fold is used as the test set. This process is repeated and each of the folds is given an

In k-fold cross-validation, the data is first partitioned into k equally (or nearly equally) sized segments or folds. Subsequently k iterations of training and validation are performed such that within each iteration a different fold of the data is held-out for validation while the remaining k − 1 folds are used for learning. Fig. 1 demonstrates an example with k= 3

I train a binary random forest classifier on scikit-learn's 20 newsgroups dataset. I want to tune the parameters and try so by gridsearch and 3-fold cross validation on the training data. Is there any problem with this methodology? For the max_depth parameter I get a really high value of 500 and that seems too high. Any advice? The code is:

scikit-learn documentation: Cross-validation. Example. Learning the parameters of a prediction function and testing it on the same data is a methodological mistake: a model that would just repeat the labels of the samples that it has just seen would have a perfect score but would fail to predict anything useful on yet-unseen data
