Multi-class boosting with asymmetric binary weak-learners

作者:

Highlights:

• Multi-class boosting procedure with binary weak-learners.

• Novel multi-class vectorial encoding producing different margin values.

• Margins depend on the asymmetry of the problem posed to the weak-learner.

• Provides statistically significant improvements in performance.

• Opens research venues in multi-{class,label,dimensional} classification.
