研究人员开发了XtrAIn，一种用于机器学习模型特征归因的新颖方法。该技术通过将遮挡操作从输入空间转移到参数空间，解决了传统基于遮挡的方法的问题。XtrAIn分析与特征相关的参数更新在训练期间如何影响模型输出，为理解特征重要性提供了一种更稳定、更具可解释性的方法。Xstep和XtrAIn+等变体进一步提高了计算效率和目标特定分析，在图像和医学数据集上显示出改进的归因模式。 AI

Occlusion-based attribution methods provide an intuitive way to estimate feature importance by perturbing input features and measuring the resulting change in model output. However, their reliability is strongly affected by how feature removal is implemented: externally selected …
