Deep learning for quality prediction of nonlinear dynamic processes with variable attention‐based long short‐term memory network

Abstract: Industrial processes are often characterized with high nonlinearities and dynamics.For soft sensor modelling, it is important to model the nonlinear and dynamic relationship between input and output data. Thus, long short-term memory (LSTM) networks are suitable for quality prediction of soft sensor modelling. However, they do not consider the relevance of different input variables with the quality variable. To address this issue, a variable attention-based long short-term memory (VA-LSTM) network is proposed … Show more

“…In recent years, deep learning methods, such as stacked auto-encoder (SAE) (Qiu and Dai, 2019; Zheng and Zhao, 2020), DBN (Yu and Liu, 2020; Yu and Yan, 2019), convolutional neural network (Zhao et al , 2019; Wu and Zhao, 2018) and long short-term memory (Han et al , 2020; Yuan et al , 2020), have been developed and widely applied in many scenarios, and they have played an important role in minimizing feature redundancy and capturing significant features. Deep learning methods are currently the most appealing feature extraction technology that has achieved brilliant success in processing high-dimensional complex data (Wang et al , 2020).…”

“…An approach to use ML to optimize makespan in job shop scheduling problems can be found in (Dao et al, 2018). Deep learning methods for example are used to predict product quality with data from parallel (Zhenyu et al, 2020) or dynamic non-linear processes (Wang & Jiao, 2017;Yuan et al, 2020). Also, there are data-driven approach for complex production systems (Ren et al, 2020).…”

“…Although the LSTM based modeling issue has been studied for a long time, the history of its applications on the data-driven industry process modeling and quality prediction is only a few years. The LSTM based method has been proved as an efficient soft sensor model for nonlinear dynamic industrial processes, which can provide a better performance than the traditional models such as PLS, SAE and RNN [31].…”
