* fast optimization algorithm o working set selection based on steepest feasible descent o "shrinking" heuristic o caching of kernel evaluations o use of folding in the linear case * solves classification and regression problems. For multivariate and structured outputs use SVMstruct. * solves ranking problems (e. g. learning retrieval functions in STRIVER search engine). * computes XiAlpha-estimates of the error rate, the precision, and the recall * efficiently computes Leave-One-Out estimates of the error rate, the precision, and the recall * includes algorithm for approximately training large transductive SVMs (TSVMs) (see also Spectral Graph Transducer) * can train SVMs with cost models and example dependent costs * allows restarts from specified vector of dual variables * handles many thousands of support vectors * handles several hundred-thousands of training examples * supports standard kernel functions and lets you define your own * uses sparse vector representation
