8th European Conference on Principles and Practice of Knowledge Discovery in Databases, PKDD 2004
作者: de Pina, Aloísio Carlos Zaverucha, Gerson Universidade Federal do Rio de Janeiro COPPE/PESC Department of Systems Engineering and Computer Science C.P. 68511 Rio de JaneiroRJCEP. 21945-970 Brazil
RISE is a well-known multi-strategy learning algorithm that combines rule induction and instance-based learning. It achieves higher accuracy than some state-of-the-art learning algorithms, but for large data sets it h... 详细信息
