Classification methods with linear computational complexity O(nd) in the number of samples n and their dimensionality d often give results that are better or at least statistically not significantly worse that slower algorithms. This is demonstrated here for many benchmark datasets downloaded from the UCI Machine Learning Repository. Results provided in this paper should be used as a reference for estimating usefulness of new learning algorithms: higher complexity methods should provide significantly better results to justify their use.
