Abstract

Dissolved oxygen content prediction plays an important role in the intelligence management of aquaculture systems. Compared with traditional point prediction, interval prediction can quantify the uncertainties effectively and more closes to the fact. Unfortunately, there is rarely study about it. In this paper, a novel interval prediction method based on a deep auto-regression recurrent neural network (DeepAR) is proposed to construct prediction intervals (PIs) directly. Besides, a variational mode decomposition (VMD) has been used to extract the frequency feature of the original data. Moreover, a multi-objective weighted optimization framework based on the sparrow swarm algorithm (SSA) was proposed to improve PIs accuracy. Finally, simulations with water quality datasets were conducted to show the effectiveness of the proposed model. The results demonstrated that the proposed model significantly improved PI quality and performance compared to the state-of-the-art method.
