Erratum: Prediction of dissolved oxygen content in aquaculture based on clustering and improved ELM (IEEE Access (2021) 9 (40372-40387) DOI: 10.1109/ACCESS.2021.3064029)

Abstract

In the above article [1], we had followed the PLS-SELM method proposed by Shi et al. [2]. This method greatly improves the performance of the traditional network and improves the prediction accuracy. The article [2] has been cited as [40] in the original manuscript [1], and in this correction article, we want to emphasize that the PLS-SELM method provided a substantive base for our article. Therefore, we add the following explanation to Section III, titled 'Related Work'.
