Feature extraction of diesel engine fault data based on rough set theory
Maoyun Guo · Computer Engineering and Applications Journal · 2011
Rough set theory is used to research how to extract features of diesel engine fault data due to its own character.Rough set can deal with discrete data only and most parameters are continuous,so this paper presents a discretization method which uses SOM for rough set;it gives a quick attribute reduction algorithm based on simplified discernibility matrix;it extracts features of 6135D diesel engine fault data,reduces its attributes from 8 to 3 successfully and lays the foundation of follow-up work.
