要旨:
Convex learning algorithms, such as Support Vector Machines (SVMs), are often
seen as highly desirable because they offer strong practical properties and are
amenable to theoretical analysis. However, in this work we show how nonconvexity
can provide scalability advantages over convexity. We show how concave-convex
programming can be applied to produce (i) faster SVMs where training errors are
no longer support vectors, and (ii) much faster Transductive SVMs.
