A Hybrid Neural Network Model for Marine Dissolved Oxygen Concentrations Time-Series Forecasting Based Article

Hui Liu, Rui Yang, Zhu Duan, Haiping Wu

Engineering 2021, Volume 7, Issue 12,   Pages 1751-1765 doi: 10.1016/j.eng.2020.10.023

Abstract:

Dissolved oxygen (DO) is an important indicator of aquaculture, and its accurate forecasting can effectivelyIn this paper, a new DO hybrid forecasting model is proposed that includes three stages: multi-factorSecond, the series of DO, water temperature, salinity, and oxygen saturation are decomposed adaptivelyThe ensemble weights of these five sub-forecasting models are calculated by particle swarm optimizationExample analysis demonstrates that: ① the proposed model can obtain excellent DO forecasting results;
