| 總結: | Financial time series prediction is inherently complex due to its nonlinear, nonstationary, and highly volatile nature. This study introduces a novel CEEMDAN-BO-LSTM model within a decomposition-optimization-prediction- integration framework to address these challenges. The Complete Ensemble Empirical Mode Decomposition with Adaptive Noise (CEEMDAN) algorithm decomposes the original series into high- frequency, medium-frequency, low-frequency, and trend components, enabling precise time window selection. Bayesian Optimization (BO) algorithm optimizes the parameters of a dual- layer Long Short-Term Memory (LSTM) network, enhancing prediction accuracy. By integrating predictions from each component, the model generates a comprehensive and reliable forecast. Experiments on 10 representative global stock indices reveal that the proposed model outperforms benchmark approaches across RMSE, MAE, MAPE, and R2 metrics. The CEEMDAN-BO-LSTM model demonstrates robustness and stability, effectively capturing market fluctuations and long-term trends, even under high volatility. |
