improved algorithm for adaboost with svm base classifiers

... be known a priori before boosting begins. majority vote of the T base classifiers where at is the In practice, knowledge of such a bound is very difficult weight that assigned to ht . to obtain. AdaBoost, on the other hand, is adaptive in that The algorithm for AdaBoost is given below: it adapts to the error rates of the individual base 1. Input: a set of training samples with...
