WitrynaThe widely used Classification and Regression Trees (CART) have played a major role in health sciences, due to their simple and intuitive explanation of predictions. Ensemble methods like gradient boosting can improve the accuracy of decision trees, but at the expense of the interpretability of the generated model. Witryna12 kwi 2024 · Table 6 shows the results of VGG-16 with a decision tree. This hybrid achieved an accuracy of 66.15%. Figure 14 displays the VGG-16 decision tree confusion matrix. We achieved a significant number of false-positives (97 pictures) and a low number of genuine negatives (189 images).
