摘要
针对汽车销量时间序列数据的季节性、非线性性、非平稳性等复杂特征,提出一种融合变分模态分解(Varia-tional Mode Decomposition,VMD)的卷积神经网络(Convolutional Neural Network,CNN)、门控循环单元(Gated Recurrent Unit,GRU)和长短期记忆(Long Short-Term Memory,LSTM)神经网络组合的汽车销量预测方法,通过VMD将汽车销量时序数据进行分解,利用CNN提取关键特征,并通过GRU与LSTM捕捉汽车时序数据的时间依赖关系.实验表明该方法有较好的预测性能.
Abstract
To address the complex characteristics about time series data of automobile sales,such as seasonality,non-linearity,and non-stationarity,this study proposed a forecasting model that integrated Variational Mode Decomposition(VMD)with Conv-olutional Neural Network(CNN),Gated Recurrent Units(GRU),and Long Short-Term Memory(LSTM)networks.The proposed method began by decomposing the automobile sales data using VMD,followed by the extraction of key features through the appli-cation of CNNs.Subsequently,the model employed GRU and LSTM networks to capture the temporal dependencies inherent in automobile sales data.Experimental results demonstrated that the proposed approach exhibited superior forecasting performance.
