Deep Domain Adaptation Model for Bearing Fault Diagnosis with Riemann Metric Correlation Alignment

Table 4

The diagnosis results of six domain shifts of the proposed method with different SNR values.

Domain shifts	SNR (dB)
A ⟶ B	−2	0	2	4	6	8	10
A ⟶ C	0.604	0.864	0.908	0.936	0.988	1	1
B ⟶ C	0.812	0.796	0.924	0.984	0.992	1	1
C ⟶ B	0.728	0.796	0.884	0.988	1	1	1
C ⟶ A	0.748	0.704	0.88	0.948	0.972	0.972	0.98
B ⟶ A	0.712	0.828	0.936	0.944	0.972	0.976	0.98
