{{Short description|Machine learning kernel function}}

In [[machine learning]], the '''[[radial basis function]] kernel''', or '''RBF kernel''', is a popular [[Positive-definite kernel|kernel function]] used in various [[kernel method|kernelized]] learning algorithms. In particular, it is commonly used in [[support vector machine]] [[statistical classification|classification]].<ref name="Chang2010">{{cite journal | last1 = Chang | first1 = Yin-Wen | last2 = Hsieh | first2 = Cho-Jui | last3 = Chang | first3 = Kai-Wei | last4 = Ringgaard | first4 = Michael | last5 = Lin | first5 = Chih-Jen | year = 2010 | title = Training and testing low-degree polynomial data mappings via linear SVM | url = http://jmlr.org/papers/v11/chang10a.html | journal = Journal of Machine Learning Research | volume = 11 | pages = 1471–1490 }}</ref>
