用故事化解释让医疗AI更可信,提升专家信任度。

AI Readiness in Healthcare through Storytelling XAI

  • 结合多任务蒸馏与可解释性技术,实现以用户为中心的AI解释。
  • 在医疗场景中提升领域专家与算法专家对AI的信任感。
  • 适用于需要高可信度解释的医疗AI部署,如诊断辅助系统。

人工智能正迅速发展并深刻影响日常生活,但其在真实医疗环境中的应用仍受限。主要原因是模型可信度不足及领域专家对预测结果的疑虑。可解释人工智能(XAI)旨在解决此问题,但不同背景的用户对可解释性的理解各异。为此,我们提出故事化XAI方法,融合多任务蒸馏与可解释性技术,实现面向特定受众的可解释性。多任务蒸馏利用任务间关联,提升解释的连贯性与有效性,使领域专家更易理解模型决策逻辑。该方法可扩展至复杂深度模型。研究同时采用模型无关与模型特定的解释方法,并通过医疗案例提供文本化结果说明。实验证明,该方法显著提升了领域专家与机器学习专家对AI系统的信任,推动负责任AI在医疗领域的落地。

原文摘要 · Abstract (English)

Artificial Intelligence is rapidly advancing and radically impacting everyday life, driven by the increasing availability of computing power. Despite this trend, the adoption of AI in real-world healthcare is still limited. One of the main reasons is the trustworthiness of AI models and the potential hesitation of domain experts with model predictions. Explainable Artificial Intelligence (XAI) techniques aim to address these issues. However, explainability can mean different things to people with different backgrounds, expertise, and goals. To address the target audience with diverse needs, we develop storytelling XAI. In this research, we have developed an approach that combines multi-task distillation with interpretability techniques to enable audience-centric explainability. Using multi-task distillation allows the model to exploit the relationships between tasks, potentially improving interpretability as each task supports the other leading to an enhanced interpretability from the perspective of a domain expert. The distillation process allows us to extend this research to large deep models that are highly complex. We focus on both model-agnostic and model-specific methods of interpretability, supported by textual justification of the results in healthcare through our use case. Our methods increase the trust of both the domain experts and the machine learning experts to enable a responsible AI.
