Figure 4
Two line graphs compare the training and validation accuracy of CNN and DenseNet121 models. The first graph shows training accuracy over 50 epochs, with DenseNet121 achieving higher accuracy than CNN. The second graph displays validation accuracy over the same epochs, again with DenseNet121 outperforming CNN. Both graphs indicate that DenseNet121 consistently achieves higher accuracy in both training and validation phases. All values are approximated.(a) Training accuracy and (b) validation accuracy of CNN and DenseNet121
