An automatic encoder extreme learning machine model is proposed to predict the NOx emission concentration based on the combination of mutual information algorithm, AE, and ELM. The experimental results show that the proposed model performs well compared to state-of-art models.
An automatic encoder (AE) extreme learning machine (ELM)-AE-ELM model is proposed to predict the NOx emission concentration based on the combination of mutual information algorithm (MI), AE, and ELM. First, the importance of practical variables is computed by the MI algorithm, and the mechanism is analyzed to determine the variables related to the NOx emission concentration. Then, the time delay correlations between the selected variables and NOx emission concentration are further analyzed to reconstruct the modeling data. Subsequently, the AE is applied to extract hidden features within the input variables. Finally, an ELM algorithm establishes the relationship between the NOx emission con-centration and deep features. The experimental results on practical data indicate that the proposed model shows promising performance compared to state-of-art models.(c) 2022 Elsevier Ltd. All rights reserved.
