But an evaluation of the recommender system is an important factor as it involves the trust of the user in the system. Various incompatible assessment methods are used for the evaluation of recommender systems, but the proper evaluation of a recommender system needs a particular objective set by ...
Evaluation of recommender systems is typically done with finite datasets. This means that conventional evaluation methodologies are only applicable in offline experiments, where data and models are stationary. However, in real world systems, user feedback is continuously generated, at unpredictable rates....

ine training and testing of recommender systems. Moreover, the root mean square error (RMSE), the most popular accuracy metric in the recommender literature, can easily be evaluated on the user-item pairs that actually have a rating value in the data. The objective of common real-world ...
This is the official repository forEvalRS @ KDD 2023:a Well-Rounded Evaluation of Recommender Systems. Aside from papers and talks, we will host a hackathon, where participants will pursue innovative projects for the rounded evaluation of recommender systems. The aim of the hackathon is to evalua...

Middleton的论文:用户实体的个人资料非常有利于基于内容的技术应用在推荐系统中。 Middleton的论文出名的三个原因: 1.它展示了一种能够推广到其他领域(如存在一个实体,且推荐系统能有效地引导用户兴趣空间); 2.它展示了一个实际存在的外部实体如何在推荐系统中处理冷启动问题(如纯粹基于系统过滤的推荐系统无法提供太多...
weaknesses and applicable conditions of different evaluation metrics are analized.The focus is concentrated on the importance of rank and some representative rank-sensitive metrics.The user-centric recommender systems are discussed and some important open problems are outlined as future possible directions....
