“…Huan et al [4] combined the ensemble empirical mode decomposition (EEMD) and a least-square support vector machine (LSSVM) to predict the dissolved oxygen sequences. Li et al [5] proposed a hybrid model of multiscale features based on EEMD and used it for dissolved oxygen prediction in aquaculture. Ren et al [6] used a genetic algorithm-optimized fuzzy neural network for the hydroponic system prediction of dissolved oxygen.…”
