no code implementations30 Nov 2015 Yangyang Xu, Ioannis Akrotirianakis, Amit Chakraborty

The Support Vector Machine (SVM) has been used in a wide variety of classification problems.

Alternating direction method of multipliers for regularized multiclass support vector machines

no code implementations30 Nov 2015 Yangyang Xu, Ioannis Akrotirianakis, Amit Chakraborty

A lot of effort has been put to generalize the binary SVM to multiclass SVM (MSVM) which are more complex problems.
