Description
Summary:Soft sensor, as an important paradigm for industrial intelligence, is widely used in industrial pro- duction to achieve efficient monitoring and prediction of production status including product quality. Data-driven soft sensor methods have attracted attention, which still have challenges because of complex industrial data with diverse characteristics, nonlinear relationships mas- sive unlabeled samples. In this paper, a data-driven self- supervised long short term memory-deep factorization ma- chine model is proposed for industrial soft sensor, in which a framework mainly including pretraining and finetuning stages is proposed to explore diverse indus- trial data characteristics. In the pretraining stage, LSTM- Autoencoder is first unsupervised pretrained. Then, based on two self-supervised mask strategies, LSTM-Deep can explore the interdependencies between features the dynamic fluctuation in time series. In the finetuning stage, relying on pretrained representation, the temporal, high-dimensional and low-dimensional features can be ex- tracted from the LSTM, Deep and FM components respec- tively.
