Researchers have developed a new regularization technique called Normal Guidance for attention-based multiple instance learning (MIL) in 3D medical image classification. This method encourages learned attention distributions to follow a bell-shaped curve, aiming to improve slice-level prediction accuracy in weakly supervised settings. Experiments on over 4 million 2D slices across three datasets show that Normal Guidance significantly enhances the slice-level localization capabilities of attention-based and transformer-based MIL methods, while maintaining competitive performance in whole-scan classification.
