Abstract

With the rapid development of e-commerce and the increasing aging population, more elderly people are engaging in online shopping. However, challenges they face during this process are becoming more apparent. This article proposes a recommendation system based on click-through rate (CTR) prediction, aiming to enhance the online shopping experience for elderly users. By analyzing user characteristics, product features, and their interactions, we constructed a model combining bidirectional long short-term memory (Bi-LSTM) and multi-head self-attention mechanism to predict the item click behavior of elderly users in the recommendation section. Experimental results demonstrated that the model excels in CTR prediction, effectively improving the relevance of recommended content. Compared to the baseline model long short-term memory (LSTM), the GATI-RS framework improved CTR prediction accuracy by 40%, and its loss function rapidly decreased and remained stable during training. Additionally, the GATI-RS framework showed significant performance improvement when considering only elderly users, with accuracy surpassing the baseline model by 42%. These results indicate that the GATI-RS framework, through optimized algorithms, significantly enhances the model's global information integration and complex pattern recognition capabilities, providing strong support for developing recommendation systems for elderly online shoppers. This research not only offers new insights for e-commerce platforms to optimize services but also contributes to improving the quality of life and well-being of the elderly.

使用 Bi-LSTM 和多头注意力机制的 GATI-RS 模型,通过准确预测点击率提升老年人的网上购物体验。
随着电子商务的快速发展和人口老龄化的加剧,越来越多的老年人开始在网上购物。然而,他们在这一过程中面临的挑战越来越明显。本文提出了一种基于点击率(CTR)预测的推荐系统,旨在提升老年用户的在线购物体验。通过分析用户特征、产品特征及其交互作用,我们构建了双向长短期记忆(Bi-LSTM)和多头自注意机制相结合的模型来预测老年用户在推荐版块的物品点击行为。实验结果表明,该模型具有较好的点击率预测能力,有效提高了推荐内容的相关性。与基线模型LSTM相比,GATI-RS框架的CTR预测准确率提高了40%,其损失函数在训练过程中迅速减小并保持稳定。此外,GATI-RS框架在仅考虑老年用户时表现出显着的性能改进,准确率比基线模型高出42%。这些结果表明,GATI-RS框架通过优化算法,显著增强了模型的全局信息集成能力和复杂模式识别能力,为开发老年人在线购物者推荐系统提供了有力支持。本研究不仅为电商平台优化服务提供了新的见解,也有助于提高老年人的生活质量和幸福感。
