Table 2.

Comparison of different machine learning models on the performance in estimation OV infectious level grading. The best performance and the next best performance are indicated in bold and italic respectively. Inline graphic represents a classification model and Inline graphic represents a regression model. The proposed models that outperform the most performant baseline, ResNet50 Inline graphic (Inline graphic) are marked with Inline graphic.
