Query: Logistic-ELM: A Novel Fault Diagnosis Method for Rolling Bearings   The fault diagnosis of rolling bearings is a critical technique to realize
predictive maintenance for mechanical condition monitoring. In real industrial
systems, the main challenges for the fault diagnosis of rolling bearings
pertain to the accuracy and real-time requirements. Most existing methods focus
on ensuring the accuracy, and the real-time requirement is often neglected. In
this paper, considering both requirements, we propose a novel fast fault
diagnosis method for rolling bearings, based on extreme learning machine (ELM)
and logistic mapping, named logistic-ELM. First, we identify 14 kinds of
time-domain features from the original vibration signals according to
mechanical vibration principles and adopt the sequential forward selection
(SFS) strategy to select optimal features from them to ensure the basic
predictive accuracy and efficiency. Next, we propose the logistic-ELM for fast
fault classification, where the biases in ELM are omitted and the random input
weights are replaced by the chaotic logistic mapping sequence which involves a
higher uncorrelation to obtain more accurate results with fewer hidden neurons.
We conduct extensive experiments on the rolling bearing vibration signal
dataset of the Case Western Reserve University (CWRU) Bearing Data Centre. The
experimental results show that the proposed approach outperforms existing SOTA
comparison methods in terms of the predictive accuracy, and the highest
accuracy is 100% in seven separate sub data environments. The relevant code is
publicly available at https://github.com/TAN-OpenLab/logistic-ELM.
