Therefore we propose three algorithms to allow for soft margin classification by introducing regularization with slack variables into the boosting concept: (1) AdaBoost$\_{reg}$ and regularized versions of (2) linear and (3) quadratic programming AdaBoost. Experiments show the usefulness of the proposed algorithms in comparison to another soft margin classifier: the support vector machine.", pdf = "http://ida.first.fhg.de/\\textasciitilde {}raetsch/ps/RaeOnoMue98d.pdf", postscript = "http://ida.first.fhg.de/\\textasciitilde {}raetsch/ps/RaeOnoMue98d.ps.gz" }
