主 题:producing action normativity sequential model attention mechanism deep learning
摘 要:The normativity of workers actions during producing has a great impact on the quality of the products and the safety of the operation *** studies mainly focused on the normativity of each single producing action instead of considering the normativity of continuous producing actions,which is defined as producing action flow(PAF)in this paper,during operation *** this issue,a normativity judging method based on two-LSTM fusion network(TFN)and normativity-aware attention network(NAN)is ***,TFN is designed to detect and recognize the producing actions based on skeleton sequences of a worker during complete operation process,and PAF data in sequential form are *** is built to allocate difTerent levels of attention to each producing action within the sequence of *** by this means,an efficient normativity judging is *** combustor surface cleaning(CSC)process of rocket engine is taken as the experimental case,and the CSC-Action2D dataset is established for *** results show the high performance of TFN and *** the effectiveness of the proposed method for PAF normativity judging.
