English(EN) When Adaptation Hurts: Connecting Representational Drift to OOD Failures in MedSAM Fine-Tuning

研究发现 MedSAM 适应会损害分布外性能

一项新的研究论文探讨了如何为医学图像分割调整 MedSAM 等基础模型,可能会无意中损害其在分布外 (OOD) 数据上的性能。该研究在 ISIC 2018 数据集上测试了六种适应策略,包括完全微调和参数高效方法,如 LoRA 和视觉提示调优。研究人员发现,虽然适应可以提高在分布内和接近分布外数据上的性能,但它通常会降低在远离分布外数据上的性能,而完全微调提供了最佳的权衡。该论文认为,解码器表征漂移是导致 OOD 性能下降的关键因素,并且仅使用编码器的 LoRA 通过保留解码器通路可以提供更好的鲁棒性。 AI

影响 强调了在专业任务中微调基础模型可能存在的陷阱,影响了医学人工智能系统的开发和验证方式。

    适应的代价:连接表征漂移与MedSAM微调中的OOD失效

    arXiv:2608.21300v1 Announce Type: new Abstract: Foundation models for medical image segmentation, like prompt-based MedSAM, generalize well across domains and modalities, often in zero or few-shot setups. However, their performance depends on the quality of prompts and the adapta…
