| 摘 要： | 针对长短期记忆网络(long short-term memory,LSTM)无法有效提取温度数据的多尺度特征和反向特征的问题,该文提出了一种双向多尺度跳跃LSTM(bidirectional multi-scale skip long short-term memory,BMS-LSTM)的短时温度预测模型.该模型以LSTM为核心单元,采用双向深层网络结构提取反向特征; 根据温度数据日的周期性设置跳跃连接数提取多尺度特征,解决了指数增长的跳跃连接数后期跳跃尺度过大的问题; 最后使用全连接层进行特征融合预测.实验结果表明:BMS-LSTM成功提取了温度数据的多尺度特征和反向特征,预测均值误差仅为3.890,优于对比模型,是一种有效的短时温度预测模型.

| Abstract: | Because at the LSTM(Long Short-Term Memory)cannot effectively extract the multi-scale features and inverse features of temperature data,the BMS-LSTM(Bidirectional Multi-scale Skip Long Short-Term Memory)short-term temperature prediction model is proposed.The model uses LSTM as the core unit,and uses a two-way deep network structure to extract reverse features.The multi-scale feature is extracted according to the daily cycle setting of the number of jump connections in the temperature data,which solves the problem of the jump scale being too large in the later stage of the exponentially increasing number of jump connections.Finally,the fully connected layer is used for feature fusion prediction.The experiment's results show that BMS-LSTM has successfully extracted the multi-scale features and reverse features of temperature data,and the average prediction error is only 3.890,which is better than the comparison model and is an effective short-term temperature prediction model. |
