Abstract: To improve the accuracy of module-level fault diagnosis for avionics, a new off-line diagnosis method based on soft-clustering-sensitive Localized Multi-Kernel Learning (LMKL) and Extreme Learning Machine (ELM) is proposed. By introducing fuzzy C-means clustering to partition the sample space, the over-learning is suppressed while mining the diversity within the cluster. The membership information generated by the fuzzy partition is integrated into the optimization process of LMKL-ELM. A three-step optimization strategy based on the initial-dual hybrid optimization problem is used to overcome the quadratic non-convexity of the local kernel weights. The corresponding updating methods for these weights are given under l1-norm constraint and l2-norm constraint. The proposed method is applied to the front-end receiver. Compared with four popular multi-kernel diagnostic algorithms, the results show that the proposed method can effectively avoid missing alarm and suppress false alarm. The diagnostic accuracy is 4.09% higher in l1-norm and 5.13% higher in l2-norm than the average of other methods.
