Figure 4. Analysis of the relationship between features and target performance in the source and target domains. (A) and (B) display the PCC between features and target performance across the source and target domains; (C) illustrates the MMD of features in both domains; (D-F) present scatter plots of the generated GPF1, GPF2, and GPF3 with standardization against target performance, along with their respective PCC and MMD values. PCC: Pearson correlation coefficient; MMD: maximum mean discrepancy.
