Reconstructing A Framework for Predicting University Tuition Payment Trends Using Temporal Fusion Transformer
Main Article Content
Abstract
To improve the prediction accuracy and interpretability of complex university tuition payment time series, this paper proposes a reconstructed forecasting framework based on the Temporal Fusion Transformer. The framework encodes multi-source heterogeneous data, including static and dynamic variables such as student majors, economic status, scholarship disbursement plans, and real-time payment reminders, into a low-dimensional representation space. A sigmoid gated network dynamically weights informative variables and suppresses redundant features. LSTM modules and a specialized three-head attention mechanism for time patterns, group synchronization, and policy response are jointly used to model long-term dependencies and capture nonlinear payment fluctuations. Interpretable multi-step forecasts are generated by combining sequence outputs with attention weights. Experimental results show that the model achieves RMSE ≤0.08 and MAE ≤0.07 during peak payment periods, with R2 above 0.9 in five disturbance scenarios, demonstrating strong dynamic adaptability. Interpretability analysis yields a Pearson correlation coefficient of at least 0.68 and an information gain ratio of at least 0.7, confirming robust feature attribution and discriminative capability.
