Based on real sales data, this article constructed LGBM and LSTM sales prediction models to compare and verify the performance of the proposed models. In this article, we forecast the product sales of stores in the future + 3 days and use MAPE as the evaluation index. The experiment shows that the product sales prediction model based on the convolutional LSTM (ConvLSTM) network has better prediction accuracy. From a store point of view, ConvLSTM prediction model MAPE was 0.42 lower than the long short-term memory (LSTM) network and 0.68 lower than LGBM. From the perspective of commodity categories, different commodity categories are suitable for different forecasting methods. Some categories are suitable for regression forecasting, while others are suitable for time-series forecasting. Among the categories suitable for time-series forecasting, the ConvLSTM model performs the best.
基于真实销售数据,本文构建了 LGBM 和 LSTM 销售预测模型,以比较和验证所提出模型的性能。在本文中,我们预测了未来 3 天内商店的产品销售情况,并使用 MAPE 作为评估指标。实验表明,基于卷积长短期记忆网络(ConvLSTM)的产品销售预测模型具有更好的预测准确性。从商店的角度来看,ConvLSTM 预测模型的 MAPE 比长短期记忆网络(LSTM)低 0.42,比 LGBM 低 0.68。从商品类别来看,不同的商品类别适用于不同的预测方法。有些类别适合回归预测,而有些则适合时间序列预测。在适合时间序列预测的类别中,ConvLSTM 模型表现最佳。
