Analyzing QAR Data Using K-PCA

2008 Workshop on Power Electronics and Intelligent Transportation System, 2008
This paper analyzes the drawbacks of traditional principal component analysis (PCA) firstly, and discusses the kernel principal component analysis (KPCA) as well as its drawbacks of high complexity secondly. Then it proposes the K-PCA method. Comparing with KPCA, the method proposed in this paper could achieve dimensionality reduction with faster speed.

Grey Correlation Analysis of Hard Landing Based on QAR Data

2019 IEEE 1st International Conference on Civil Aviation Safety and Information Technology (ICCASIT), 2019
In this paper, an analysis model is established based on grey theory, and the key flight control parameters of hard landing events are studied by using Quick Access Recorder (QAR) decoded data. By analyzing the real QAR decoded data of aircraft hard landing, the correctness of the method is verified by first calculating the grey absolute correlation ...
