WebJan 23, 2009 · We study boosting algorithms from a new perspective. We show that the Lagrange dual problems of AdaBoost, LogitBoost and soft-margin LPBoost with generalized hinge loss are all entropy maximization problems. By looking at the dual problems of these boosting algorithms, we show that the success of boosting algorithms can be understood … WebHinge loss The hinge loss is used in the setting of SVMs and is defined as follows: \ [\boxed {L (z,y)= [1-yz]_+=\max (0,1-yz)}\] Kernel Given a feature mapping $\phi$, we define the kernel $K$ as follows: \ [\boxed {K (x,z)=\phi (x)^T\phi (z)}\]
