Kernel Regression Residual Decomposition Method to Detect Rolling Element Bearing Faults

<div>The KRRD method using Case Western Reserve University data. (a) Raw signal S1 is decomposed into four residual signals S2, S3, S4, and S5. (b) Each residual signal is decomposed into C1, C2, C3, C4, and C5 using noise suppression.</div>
