摘要

随着技术的发展,教育资源的分配和使用变得越来越复杂。由于英语教育资源的推荐和匹配涉及诸多因素,传统的预测控制模型已不再适用。因此,基于神经网络的模糊预测控制模型应运而生。为了提高英语教育资源(EER)的使用效果和效率,本研究旨在创建一个基于神经网络的模糊预测控制模型(T-S-BPNN),用于资源推荐和匹配。研究结果表明,本研究提出的 T-S-BPNN 模型 α 从 0 开始,依次增加 0.1 至 1,观察 MAE 值的变化。实验结果表明,MAE 值在 0.5 左右时最低。另一方面,T-S-BPNN 模型的适应率在运行 7 次后逐渐趋于平稳,达到约 9.8%。当推荐课程数达到 7 门时,准确率达到峰值 0.843;当推荐英语课程数达到 7 门时,召回率也达到峰值 0.647。而训练集的 R 值为 0.97024,可以说明研究中提出的 T-S-BPNN 模型拟合良好。这表明本研究提出的算法具有很强的实用性。

Application of fuzzy prediction control model based on neural network in teaching resource recommendation and matching
As technology evolves, the allocation and use of educational resources becomes increasingly complex. Due to the many factors involved in recommending and matching English education resources, traditional predictive control models are no longer adequate. Therefore, fuzzy predictive control models based on neural networks have emerged. To increase the effectiveness and efficiency of using English educational resources (EER), this research aims to create a neural network-based fuzzy predictive control model (T-S-BPNN) for resource suggestion and matching. The results of the study show that the T-S-BPNN model α proposed in the study starts from 0 and increases sequentially by 0.1 up to 1, observing the change in MAE values. The experiment’s findings demonstrate that the value of MAE is lowest at values around 0.5. The T-S-BPNN model, on the other hand, gradually plateaued in its adaptation rate up to 7 runs, reaching about 9.8%. The accuracy rate peaked at 0.843 when the number of recommendations reached 7. The recall rate also peaked at 0.647 when the number of recommended English courses reached 7. The R-value for each set hovered around 0.97, which is a good fit. And the R-value of the training set is 0.97024, which can indicate that the T-S-BPNN model model proposed in the study fits well. It indicates that the algorithm proposed in the study is highly practical.
