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.

ST-RAP: A Spatio-Temporal Framework for Real Estate Appraisal

1 code implementation21 Aug 2023 Hojoon Lee, Hawon Jeong, Byungkun Lee, Kyungyup Lee, Jaegul Choo

In this paper, we introduce ST-RAP, a novel Spatio-Temporal framework for Real estate APpraisal.

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.
