Soft margins for adaboost
WebWe propose several regularization methods and generalizations of the original ADABOOST algorithm to achieve a soft margin. In particular we suggest (1) regularized ADABOOST REG where the gradient decent is done directly with respect to the soft margin and (2) … Webreplace the hard constraints with soft constraints, which one is allowed to violate, but at a penalty. This model is known as a soft-margin SVM, and the formulation from the preceding section is known as the hard-margin SVM. We represent the soft constraints by introducing some slack variables ˘ iwhich determine the size of the violation. We ...

Minimizing this regularized exponential loss results in a boosting algorithm that relaxes the weak learning assumption further: it can use classifiers with error greater than \frac {1} {2}. asal nusantara
