Bundle MCR: Towards Conversational Bundle Recommendation

1 code implementation26 Jul 2022 Zhankui He, Handong Zhao, Tong Yu, Sungchul Kim, Fan Du, Julian McAuley

MCR, which uses a conversational paradigm to elicit user interests by asking user preferences on tags (e. g., categories or attributes) and handling user feedback across multiple rounds, is an emerging recommendation setting to acquire user feedback and narrow down the output space, but has not been explored in the context of bundle recommendation.

Personalized Visualization Recommendation

no code implementations12 Feb 2021 Xin Qian, Ryan A. Rossi, Fan Du, Sungchul Kim, Eunyee Koh, Sana Malik, Tak Yeon Lee, Nesreen K. Ahmed

Visualization recommendation work has focused solely on scoring visualizations based on the underlying dataset and not the actual user and their past visualization feedback.

ML-based Visualization Recommendation: Learning to Recommend Visualizations from Data

no code implementations25 Sep 2020 Xin Qian, Ryan A. Rossi, Fan Du, Sungchul Kim, Eunyee Koh, Sana Malik, Tak Yeon Lee, Joel Chan

Finally, we observed a strong preference by the human experts in our user study towards the visualizations recommended by our ML-based system as opposed to the rule-based system (5. 92 from a 7-point Likert scale compared to only 3. 45).
