Uncertainty-Weighted Mutual Distillation for Multi-View Fusion

Multi-view learning often faces challenges in effectively leveraging images captured from different angles and locations. This challenge is particularly pronounced when addressing inconsistencies and uncertainties between views. In this paper, we propose a novel Multi-View Uncertainty-Weighted Mutual Distillation (MV-UWMD) method. Our method enhances prediction consistency by performing hierarchical mutual distillation across all possible view combinations, including single-view, partial multi-view, and full multi-view predictions. This introduces an uncertainty-based weighting mechanism through mutual distillation, allowing effective exploitation of unique information from each view while mitigating the impact of uncertain predictions. We extend a CNN-Transformer hybrid architecture to facilitate robust feature learning and integration across multiple view combinations. We conducted extensive experiments using a large, unstructured dataset captured from diverse, non-fixed viewpoints. The results demonstrate that MV-UWMD improves prediction accuracy and consistency compared to existing multi-view learning approaches.

Preoperative Rotator Cuff Tear Prediction from Shoulder Radiographs using a Convolutional Block Attention Module-Integrated Neural Network

Research question: We test whether a plane shoulder radiograph can be used together with deep learning methods to identify patients with rotator cuff tears as opposed to using an MRI in standard of care. Findings: By integrating convolutional block attention modules into a deep neural network, our model demonstrates high accuracy in detecting patients with rotator cuff tears, achieving an average AUC of 0.889 and an accuracy of 0.831. Meaning: This study validates the efficacy of our deep learning model to accurately detect rotation cuff tears from radiographs, offering a viable pre-assessment or alternative to more expensive imaging techniques such as MRI.
