用于建筑能耗预测的多尺度可解释时序预测网络模型OA
Multi-scale interpretable temporal prediction network for building energy consumption forecasting
建筑能耗预测对于优化能源管理、降低运营成本、实现碳中和目标至关重要.为提高能耗预测精度和结果的可解释性,通过长短期时序网络(long short-term temporal networks,LSTM)和科尔莫戈罗夫-阿诺德网络(Kolmogorov-Arnold networks,KAN)协同优化,提出一种多尺度可解释时序预测网络模型(interpretable temporal prediction network,ITSFN).该模型融合时序-环境特征解耦与动态注意力机制,通过显式分离时序数据的季节项、趋势项及残差项,构建结构化特征空间,采用门控循环单元(gated recurrent unit,GRU)与多头注意力的并行架构实现多尺度特征建模.在夏热冬冷地区某高校教学楼能耗数据集上进行测试,结果表明ITSFN总能耗预测RMSE较LSTM降低13.9%,分项能耗预测RMSE较Transformer降低31.1%;ITSFN通过特征解耦将噪声抑制系数提升至0.89,在突变区域实现0.92的注意力局角度,较传统方法减少29.6%的过平滑现象,且通过量化特征贡献度呈现各分量权重演化规律,验证了模型的有效性和实用性.
Accurate forecasting of building energy consumption is crucial for optimizing energy management,reducing operational costs,and achieving carbon neutrality goals.This study proposes a multi-scale interpretable temporal prediction network model(ITSFN),which enhances prediction accuracy and reliability through the collaborative optimization of long short-term temporal(LSTM)networks and Kolmogorov-Arnold networks(KAN).The model integrates temporal-environmental feature decoupling with a dynamic attention mechanism,explicitly decomposing time-series data into seasonal,trend,and residual components to construct a structured feature space.It employs a parallel architecture of gated recurrent units(GRU)and multi-head attention to model multi-scale features.Tested on an energy consumption dataset from a university building in a hot-summer/cold-winter region,ITSFN outperforms traditional models:it reduces the root mean square error(RMSE)of total energy consumption prediction by 13.9%compared to LSTM and decreases the RMSE of sub-item energy consumption prediction by 31.1%compared to Transformer.Additionally,ITSFN enhances the noise suppression coefficient to 0.89 through feature decoupling,achieves a local attention angle of 0.92 in mutation regions,and reduces over-smoothing by 29.6%compared to traditional methods.By quantifying feature contributions,the model reveals the evolutionary patterns of component weights,further validating its effectiveness and practical applicability.
