Generalized CMAC adaptive ensembles for concept-drifting data streams. González-Serrano, F. J. & Figueiras-Vidal, A. R. In 2017 25th European Signal Processing Conference (EUSIPCO), pages 2669-2673, Aug, 2017. Paper doi abstract bibtex In this paper we propose to use an adaptive ensemble learning framework with different levels of diversity to handle streams of data in non-stationary scenarios in which concept drifts are present. Our adaptive system consists of two ensembles, each one with a different level of diversity (from high to low), and, therefore, with different and complementary capabilities, that are adaptively combined to obtain an overall system of improved performance. In our approach, the ensemble members are generalized CMACs, a linear-in-the-parameters network. The ensemble of CMACs provides a reasonable trade-off between expressive power, simplicity, and fast learning speed. At the end of the paper, we provide a performance analysis of the proposed learning framework on benchmark datasets with concept drifts of different levels of severity and speed.
