Furthermore, classifiers trained with boosting-based learners have shown faster classification speed (Kudo and Matsumoto, 2004) than Support Vector Machines with a tree kernel (Collins and Duffy, 2002).
existing boosting-based algorithms for semi-structured data, boosting algorithms for classification (Kudo and Matsumoto, 2004) and for ranking (Kudo et al., 2005), have the following point that can be improved.
