English(EN) Give the Long-tail More SPACE: Promoting Provider Fairness in Next POI Recommendation

新的SPACE框架提高了推荐系统中长尾POI的公平性

研究人员开发了一个名为SPACE(Supply- and Physics-Aware Conditional Embedding generation)的新框架,以解决下一兴趣点(POI)推荐系统中的公平性问题。这些系统通常偏爱热门地点,导致不太知名的POI曝光不足。SPACE旨在通过生成尊重用户约束和POI供应限制的虚拟用户数据来提高长尾POI的曝光率。该框架包括社区推理、不平衡最优传输分配和约束引导的潜在扩散等阶段,以创建用户嵌入。然后,可以使用这些生成的数据来训练现有的推荐模型,而无需进行架构更改,实验表明这可以提高提供者公平性并保持推荐准确性。 AI

影响 通过确保不太受欢迎的兴趣点获得充分的曝光,提高了基于位置服务的公平性。

    为长尾提供更多SPACE:促进下一代POI推荐中的提供商公平性

    Next point-of-interest (POI) recommendation predicts users' future destinations from historical mobility sequences and has become a key component of location-based services. However, mainstream models often concentrate exposure on a small set of popular POIs, leaving long-tail me…
