WebThe sum of the fitted linear and nonlinear variations was the CPI forecasted by the ARIMA-BP integrated intelligent algorithm. Results demonstrated that the ARIMA-BP integrated intelligent algorithm could achieve high-precision fitting of the historical CPI data of China. Here, we propose a hybrid ARIMA-LSTM model optimized by BP, among which the ARIMA model obtains the linear components and the LSTM model obtains the nonlinear components (Qian et al. 2024). The most obvious advantage of LSTM networks is their ability to precisely retain and remember information in long sequences or time series ...
