machine health monitoring (mhm) is of great importance mechanical systems, such as vehicles, trains, airplanes, etc. it is able to reduce the maintenance cost and improve the reliability of the systems. a key task in mhm is the prediction of machine remaining useful life (rul). however, due to the high complexity of modern mechanical systems, accurate prediction of machine rul is very challenging. artificial intelligence which is capable of modelling highly non-linear and complex systems can be a good candidate. in this presentation, we attempt to address three fundamental questions in rul prediction via proposing efficient and adaptive ai models: 1) how to achieve accurate rul prediction with advanced machine learning methods? 2) how to achieve rul prediction on edge devices which have limited computational resources? 3) how to deal with cross-domain rul prediction? to solve these challenging, but practical issues, we proposed an attention based lstm method for accurate rul predication, an efficient kdnet-rul framework for compressing deep neural networks for rul prediction on edge devices, and an adaptive cross-domain rul perdition algorithm. extensive experiments have been conducted to verify the effectiveness of the proposed methods.
