AI总结:

本文提出一种量化信息迁移价值的方法,基于实验室飞机模型群体,通过相似性评估和效能预测优化迁移学习策略,以改善结构健康监测中的决策。

摘要:

在传统的结构健康监测方法中,常面临标记数据可用性相关的挑战。基于群体的结构健康监测旨在通过迁移学习等技术,利用相似结构的数据/信息来克服这些挑战。本文展示了一种在运维决策背景下量化信息迁移价值的方法。该演示基于一组实验室规模的飞机模型,强调了评估信息迁移预期价值所需的步骤,包括相似性评估和迁移效能的预测。一旦针对给定群体进行了评估,信息迁移的价值可用于优化新获取目标域的迁移学习策略。

英文摘要:

In traditional approaches to structural health monitoring, challenges often arise associated with the availability of labelled data. Population-based structural health monitoring seeks to overcomes these challenges by leveraging data/information from similar structures via technologies such as transfer learning. The current paper demonstrate a methodology for quantifying the value of information transfer in the context of operation and maintenance decision-making. This demonstration, based on a population of laboratory-scale aircraft models, highlights the steps required to evaluate the expected value of information transfer including similarity assessment and prediction of transfer efficacy. Once evaluated for a given population, the value of information transfer can be used to optimise transfer-learning strategies for newly-acquired target domains.
