📖 Full Retelling
Researchers Luisa Gallee, Meinrad Beer, and Michael Goetz introduced Proto-Caps, an innovative medical image classification method, at the MICCAI 2023 conference on October 24, 2023, addressing the critical need for interpretable AI in medical diagnostics. Proto-Caps represents a significant advancement in medical imaging AI by combining capsule networks, prototype learning, and privileged information during training. This approach allows the model to not only achieve high accuracy but also provide explanations for its decisions - a crucial feature in healthcare applications where understanding the reasoning behind AI recommendations is as important as the recommendations themselves. The researchers evaluated their solution on the LIDC-IDRI dataset, demonstrating remarkable results with over 6% higher accuracy compared to explainable baseline models, reaching 93.0% accuracy in predicting malignancy and mean characteristic features of lung nodules. The model's ability to provide case-based reasoning through prototype representations enables visual validation of radiologist-defined attributes, creating a bridge between AI analysis and medical expertise.

Advanced deep learning methods are required to address this need for explainability and high performance. In this work, we investigate whether additional information available during the training process can be used to create an understandable and powerful model. We propose an innovative solution called Proto-Caps that leverages the benefits of capsule networks, prototype learning and the use of privileged information. Evaluating the proposed solution on the LIDC-IDRI dataset shows that it combines increased interpretability with above state-of-the-art prediction performance. Compared to the explainable baseline model, our method achieves more than 6 % higher accuracy in predicting both malignancy (93.0 %) and mean characteristic features of lung nodules. Simultaneously, the model provides case-based reasoning with prototype representations that allow visual validation of radiologist-defined attributes.
