Researchers have developed SurgCSS, a new framework designed to improve surgical instrument segmentation in neural networks, particularly addressing the challenge of data imbalance in incremental learning scenarios. This imbalance, occurring both between new and old data and within specific time points, can lead to a bias in segmentation models and catastrophic forgetting of previously learned instruments. SurgCSS tackles these issues by generating balanced datasets through realistic background blending and employing a Class Desensitization Loss with contrastive learning to correct edge biases. The framework also dynamically fuses model weights to optimize the trade-off between learning new and retaining old information, demonstrating significant performance improvements over existing methods on a newly constructed benchmark.
