摘要

学费是学生接受培训后每年必须支付的费用。这些学费会因多种因素而变化。在这些因素中,有些会影响学费的增长,而有些则能确保学费适中。因此,本研究旨在分析这些因素,并将其作为预测因素纳入深度学习模型,以预测大学学费。因此,作者使用了基于刚果公投大学(UAC)学费二手数据的定量分析。这些数据被用于开发两个回归神经网络模型,即三隐藏层神经网络和四隐藏层神经网络,以确定用于预测和部署目的的最佳模型。用于评估这两个模型性能的指标是平均绝对误差、均方误差、均方根误差和判定系数。结果显示,学业成本随着学生的晋升而增加。在建立了这些模型之后,虽然它们的性能都先后达到了 95.3% 和 95.6%,但还是采用了隐藏的 4 层模型。作为特征的预测因子有六个:学年、晋升、学费、论文费、兼职讲师费和设备费。

Deep Learning for Predicting University Academic Fees in a Semi-Urban Area
Academic fees are an annual amount that students must pay in return for the training they receive. These fees can change according to several factors. Among these factors, some can influence the increase of tuition fees, while others can ensure that fees are moderate. Therefore, this research aimed to analyze these factors and integrate them as predictors in a deep-learning model for predicting university tuition fees. Hence, the authors used quantitative analysis based on secondary data on tuition fees at the Université de l’Assomption au Congo (UAC). These data were used to develop two regressive neural network models, namely the three-hidden-layer neural network and the four-hidden-layer neural network, to determine the best model for prediction and deployment purposes. The metrics used to evaluate the performance of these two models were mean absolute error, mean square error, root mean square error and coefficient of determination. The results revealed that academic costs increase as a student moves up the promotion ladder. After developing these models, although they all performed successively at 95.3% and 95.6%, the hidden 4-layer model was deployed. The predictors used as features were six: academic year, promotion, tuition fees, dissertation fees, partial time lecturers fees and equipment fees.
