Out-of-core classification of text documents. . This is an example showing how scikit-learn can be used for classification using an out-of-core approach learning from data that doesnt fit into main memory. We make use of an online classifier, i.e., one that supports the partialfit method, that will be fed with batches of examples.
The support vector machine SVM is a popular classi cation technique. However, beginners who are not familiar with SVM often get unsatisfactory results since they miss some easy but signi cant steps. In this guide, we propose a simple procedure which usually gives reasonable results. 1 Introduction
Classification Ensembles. Boosting, random forest, bagging, random subspace, and ECOC ensembles for multiclass learning. A classification ensemble is a predictive model composed of a weighted combination of multiple classification models. In general, combining multiple classification models increases predictive performance.
