Panels a, b, c and d depict the five-evaluation metrics of the classification models under positive, neutral, negative and emotion fusion conditions, respectively. The labels 1, 2, 3, and 4 on the horizontal axis correspond to the ResNet18, ResNet18_ASE, ResNet18_MFCC, and ResNet18_ASE_MFCC models, respectively. Panel e highlights the improvements in sensitivity and specificity for schizophrenia classification, achieved through feature fusion across various emotional conditions
