基于CF-EEMD-LSSVR算法的铅冶炼系统 温室气体排放的评估与预测
Evaluation and prediction of greenhouse gas emission of lead smelting system based on CF-EEMD-LSSVR
摘要
Abstract
Input-output (I-O) model for each step of lead smelting system to evaluate greenhouse gas emission per unit product was established based on carbon footprint (CF) theory. Due to the nonlinear characteristic of greenhouse gas emission data, a prediction model was developed based on the combination of ensemble empirical mode decomposition (EEMD) and the least square support vector regression (LSSVR).The procedures were as follows: the data of greenhouse gas emission of leads melting system was firstly decomposed into a series of relatively stable intrinsic mode functions (IMF), and then they were separately predicted by LSSVR. The predicted values were compared with the real results. The results show that the root mean square error of the predicted values and the real results is 2.8961%, which verifies that the proposed method can realize the accurate evaluation and prediction of greenhouse gas emission of lead smelting system.关键词
