## DC models for spherical separation.(English)Zbl 1206.90120

Summary: We propose two different approaches for the spherical separation of two sets. Both methods are based on minimizing appropriate nonconvex nondifferentiable error functions, which can be both expressed in a DC (difference of two convex) form. We tackle the problem by adopting the DC-algorithm. Some numerical results on classical binary datasets are reported.
