WebApr 11, 2024 · The learning curves of the models are featured in Figure 8. This highlights the suppression of the overfitting issue, yet there remains a substantial gap between the validation set and test set accuracy. For example, DenseNet121-PS demonstrated a maximum accuracy of 90% in the validation set, while reaching only 72.13% in the test set. WebJan 21, 2024 · A low cross-validation score means that the particular model isn't correctly learning the trend in your data, either it is overfitting or underfitting. $\endgroup$ – Jay Ekosanmi Jan 21, 2024 at 16:31
