es and abstracts of these six papers are listed below: Paper 1: Title: Sensor fault identification based on error-correcting output codes method Authors: Rui Zhou, Jie Chen, Fang Deng; Beijing Institute of Technology, China : In this paper, we proposed a method within the framework of Error-Correcting Output Codes (ECOC) to solve sensor fault feature extraction and online identification problem. Time and frequency domain signal features are selected as the initial fault characteristics, and we enhance the separability of initial characteristics by a nonlinear transformation based on the probabilistic confidence of the first ECOC outputs. Then construct the second ECOC to classify the fault state taking the feature extracted from the first ECOC as the input. We compared the accuracy and efficiency with this method between different ECOC coding strategies. The results indicate that some certain coding combination show better results on efficiency and accuracy, being able to meet the dema...
