Abstract: Cross-border trade export forecasting is important for enterprises to optimise resource allocation. However, existing prediction methods have the problem of insufficient single modal feature extraction, for this reason, this paper first optimises the reinforcement learning (RL) algorithm based on multilevel strategy and multilevel reward (MSRL). Then CNN, Doc2Vec model, and improved ResNet152 model were used to extract static variable features, comment text features, and image features of cross-border trade export sales volume, respectively, and a hierarchical attention mechanism was designed to fuse multimodal features. The hyperparameters of the BiGRU model are optimised using MSRL (MSRL-BiGRU), and the fusion features are input into MSRL-BiGRU, which efficiently and automatically searches for the optimal strategy and reduces the prediction error. The experimental results show that the proposed method improves the coefficient of determination R2 by 4.84-18.67%, which can realise the accurate prediction of cross-border trade export sales.
Keywords: cross-border trade export forecasting; reinforcement learning; multimodal fusion; hierarchical attention mechanism; BiGRU model.
