a Loss plot of PCM-AAE. b Performance comparison between non-balanced model (NB) and reconstructed model with augmented data from generators trained by PCM-AAE. Statistical significance of the difference between the performance of NB and PCM-AAE was determined by paired t-test. ns: p > 0.05; *p < 0.05; **p < 0.01; ***p < 0.001; ****p < 0.0001
