WebarXiv.org e-Print archive WebSep 6, 2024 · Sub-sampling is a common and often effective method to deal with the computational challenges of large datasets. However, for most statistical models, there is no well-motivated approach for drawing a non-uniform subsample.

WebSubsampling ( Fig. 1.36) is a method that reduces data size by selecting a subset of the original data. The subset is specified by choosing a parameter n, specifying that every n th data point is to be extracted. WebYou can use a support vector machine (SVM) when your data has exactly two classes. An SVM classifies data by finding the best hyperplane that separates all data points of one class from those of the other class. The best hyperplane for an SVM means the one with the largest margin between the two classes.
