摘要：

The theoretical achievements of data-driven machine learning models (DDM) were briefly reviewed. Then, the generalization risks of knowledge-guiding & data-driven machine learning model (KDM) in both the local learning space and global learning space were analyzed. The results show that, under certain assumptions, KDM can bound its generalization error in the local learning space approaching probability 1, and bound its generalization error in the global learning space more tightly than the generalization error of DDM with some probability 1-δ. Compared with DDM, KDM is more efficient and robust under the circumstances with limited training samples. © 2019 Chin. Soc. for Elec. Eng.
