A survey of machine-learning techniques for condition

2021-2-1  As mentioned above, bearing defects are a major source of machine defects. Because of their complexity, these defects cannot easily be detected and predicted with traditional, non-machine learning-based methods such as threshold analysis (Kankar et al., 2011).Machine learning promises better solutions for problems that normally require a lot of manual fine-tuning or cannot even be solved at
