A three layers multiple kernel learning model for analog circuit fault diagnosis
In order to improve the performance of multi-kernel diagnosis models, a novel three layers multiple kernel learning (MKL) algorithms for extreme learning machine (ELM) is presented by combining the radius-incorporated MK-ELM with AdaBoost strategy. Expand
