Cross-institution collaborations are constrained by data-sharing challenges. These challenges hamper innovation, particularly in artificial intelligence, where models require diverse data to ensure strong performance. Federated learning (FL) solves data-sharing challenges. In typical collaborations, data is sent to a central repository where models are trained. With FL, models are sent to participating sites, trained locally, and model weights aggregated to create a master model with improved performance. At the 2021 Radiology Society of North America's (RSNA) conference, a panel was conducted titled "Accelerating AI: How Federated Learning Can Protect Privacy, Facilitate Collaboration and Improve Outcomes." Two groups shared insights: researchers from the EXAM study (EMC CXR AI Model) and members of the National Cancer Institute's Early Detection Research Network's (EDRN) pancreatic cancer working group. EXAM brought together 20 institutions to create a model to predict oxygen requirements of patients seen in the emergency department with COVID-19 symptoms. The EDRN collaboration is focused on improving outcomes for pancreatic cancer patients through earlier detection. This paper describes major insights from the panel, including direct quotes. The panelists described the impetus for FL, the long-term potential vision of FL, challenges faced in FL, and the immediate path forward for FL.
跨机构合作受到数据共享挑战的限制。这些挑战阻碍了创新,尤其是在人工智能领域,模型需要多样化的数据才能确保良好的性能。联邦学习 (FL) 解决了数据共享挑战。在典型的合作中,数据被发送到中央存储库,在那里训练模型。使用 FL,模型被发送到参与的站点,在本地进行训练,并聚合模型权重,以创建具有改进性能的主模型。在 2021 年北美放射学会 (RSNA) 会议上,进行了一场名为“加速人工智能:联邦学习如何保护隐私、促进合作和改善结果”的小组讨论。两组人分享了见解:来自 EXAM 研究(EMC CXR AI 模型)的研究人员和美国国家癌症研究所早期检测研究网络(EDRN)胰腺癌工作组的成员。EXAM 将 20 个机构聚集在一起,创建了一个模型,用于预测急诊科出现 COVID-19 症状的患者的氧气需求。EDRN 合作专注于通过早期检测来改善胰腺癌患者的预后。本文介绍了小组讨论的主要见解,包括直接引语。小组成员描述了 FL 的动力、FL 的长期潜在愿景、FL 面临的挑战以及 FL 的当前前进道路。
