摘要:

随着短视频平台的快速发展,推荐系统已成为提升用户体验和增强平台参与度的关键技术。然而,短视频推荐系统在利用多模态信息(如图像、文本和音频)提高推荐效果的同时,也面临着用户隐私泄露的严峻挑战。本文提出一种基于多模态信息与差分隐私保护的短视频推荐系统。首先,利用深度学习模型对多模态数据进行特征提取与融合,有效提升推荐准确率;然后,设计适用于推荐场景的差分隐私保护机制,在保证用户数据隐私的同时维持系统性能。实验结果表明,所提方法在推荐准确率、多模态融合效果和隐私保护性能方面均优于现有主流方法,为短视频平台推荐系统设计提供重要见解。

英文摘要:

With the rapid development of short video platforms, recommendation systems have become key technologies for improving user experience and enhancing platform engagement. However, while short video recommendation systems leverage multimodal information (such as images, text, and audio) to improve recommendation effectiveness, they also face the severe challenge of user privacy leakage. This paper proposes a short video recommendation system based on multimodal information and differential privacy protection. First, deep learning models are used for feature extraction and fusion of multimodal data, effectively improving recommendation accuracy. Then, a differential privacy protection mechanism suitable for recommendation scenarios is designed to ensure user data privacy while maintaining system performance. Experimental results show that the proposed method outperforms existing mainstream approaches in terms of recommendation accuracy, multimodal fusion effectiveness, and privacy protection performance, providing important insights for the design of recommendation systems for short video platforms.
