  1. Evaluation of the statistical significance of performance differences between the Intra-epoch ViT and Inter-epoch ViT. The chi-square (χ2) values derived from this test assess whether the differences in classification performance are statistically significant. A p-value less than 0.05 is considered statistically significant.
