[Retracted] Research on Motor Bearing Fault Diagnosis Based on the AdaBoost Algorithm and the Ensemble Learning with Bayesian Optimization in the Industrial Internet of Things

Table 1

Four bearing condition types and labels.

Label	Fault type	Sampling frequency (Hz)	Damage to the inner diameter (mm)
0	Normal bearing	1200	0
1	Rolling element fault	1200	0.1778
2	Inner race fault	1200	0.3556
3	Outer race fault	1200	0.5334
