SARDINE: A Simulator for Automated Recommendation in Dynamic and Interactive Environments

1 code implementation28 Nov 2023 Romain Deffayet, Thibaut Thonet, Dongyoon Hwang, Vassilissa Lehoux, Jean-Michel Renders, Maarten de Rijke

Simulators can provide valuable insights for researchers and practitioners who wish to improve recommender systems, because they allow one to easily tweak the experimental setup in which recommender systems operate, and as a result lower the cost of identifying general trends and uncovering novel findings about the candidate methods.

Towards Validating Long-Term User Feedbacks in Interactive Recommendation Systems

no code implementations22 Aug 2023 Hojoon Lee, Dongyoon Hwang, Kyushik Min, Jaegul Choo

In this work, we revisited experiments on IRS with review datasets and compared RL-based models with a simple reward model that greedily recommends the item with the highest one-step reward.

On the Importance of Feature Decorrelation for Unsupervised Representation Learning in Reinforcement Learning

1 code implementation9 Jun 2023 Hojoon Lee, Koanho Lee, Dongyoon Hwang, Hyunho Lee, Byungkun Lee, Jaegul Choo

To address this issue, we propose a novel URL framework that causally predicts future states while increasing the dimension of the latent manifold by decorrelating the features in the latent space.

DraftRec: Personalized Draft Recommendation for Winning in Multi-Player Online Battle Arena Games

1 code implementation27 Apr 2022 Hojoon Lee, Dongyoon Hwang, Hyunseung Kim, Byungkun Lee, Jaegul Choo

To alleviate this problem, we propose DraftRec, a novel hierarchical model which recommends characters by considering each player's champion preferences and the interaction between the players.
