Abstract
Starting from a reformulation of Cramer & Singer Mul- ticlass Kernel Machine, we propose a Sequential Minimal Opti- mization (SMO) like algorithm for incremental and fast optimiza- tion of the lagrangian. The proposed formulation allowed us to dene very eective new pattern selection strategies which lead to better empirical results.
