Cleaned Similarity for Better Memory-Based Recommenders [article]

Farhan Khawar, Nevin L. Zhang
2019 pre-print
We quantify this overestimation and present a simple re-scaling and noise cleaning scheme. This results in better performance of the memory-based methods compared to their vanilla counterparts.  ...  Memory-based collaborative filtering methods like user or item k-nearest neighbors (kNN) are a simple yet effective solution to the recommendation problem.  ...  Broadly speaking, CF methods are generally characterized into memory-based and model-based methods. Memory-based methods are known for their simplicity and competitive performance [6] .  ...

Self-Guided Learning to Denoise for Robust Recommendation [article]

Yunjun Gao, Yuntao Du, Yujia Hu, Lu Chen, Xinjun Zhu, Ziquan Fang, Baihua Zheng
2022 arXiv   pre-print
Recently, some studies have noticed the importance of denoising implicit feedback for recommendations, and enhanced the robustness of recommendation models to some extent.  ...  Nonetheless, they typically fail to (1) capture the hard yet clean interactions for learning comprehensive user preference, and (2) provide a universal denoising solution that can be applied to various  ...  The memory rate is the proportion of memorized data (see Section 3.1.1 for details) in the clean and noisy interactions.  ...
