集合矩阵分解中的冷启动建议

Cold-start recommendations in Collective Matrix Factorization

David Cortes

摘要:

这项工作探讨了集体矩阵分解模型在推荐系统中对用户和项目进行预测的能力,这些用户和项目有辅助信息,但没有反馈或交互数据,并提出了一种新的公式,具有更快的冷启动预测公式,可用于实时系统。虽然这些冷启动推荐不如热启动推荐好,但发现它们比非个性化推荐质量更好,并且发现对新用户的预测比对新项目的预测更可靠。这里提出的配方导致在许多情况下改进的冷启动建议,在更差的热启动的费用。

英文摘要:

This work explores the ability of collective matrix factorization models in recommender systems to make predictions about users and items for which there is side information available but no feedback or interactions data, and proposes a new formulation with a faster cold-start prediction formula that can be used in real-time systems. While these cold-start recommendations are not as good as warm-start ones, they were found to be of better quality than non-personalized recommendations, and predictions about new users were found to be more reliable than those about new items. The formulation proposed here resulted in improved cold-start recommendations in many scenarios, at the expense of worse warm-start ones.
