Improving Recommender Systems: User Roles and Lifecycles. Nguyen, T. T In RecSys '14, pages 417–420, New York, NY, USA, 2014. ACM. Journal Abbreviation: RecSys '14![Improving Recommender Systems: User Roles and Lifecycles [link]](https://bibbase.org/img/filetypes/link.svg "link")
Paper doi abstract bibtex In the era of big data, it is usually agreed that the more data we have, the better results we can get. However, for some domains that heavily depend on user inputs (such as recommender systems), the performance evaluation metrics are sensitive to the amount of noise introduced by users. Such noise can be from users who only wanted to explore the systems, and thus did not spend efforts to provide accurate inputs. Noise can also be introduced by the methods of collecting user ratings. In my dissertation, I study how user data can affect prediction accuracies and performances of recommendation algorithms. To that end, I investigate how the data collection methods and the life cycles of users affect the prediction accuracies and the performance of recommendation algorithms.
