Mitigating Suboptimality of Deterministic Policy Gradients in Complex Q-functions

Autor: Jain, Ayush, Kosaka, Norio, Li, Xinhu, Kim, Kyung-Min, Bıyık, Erdem, Lim, Joseph J.

In reinforcement learning, off-policy actor-critic approaches like DDPG and TD3 are based on the deterministic policy gradient. Herein, the Q-function is trained from off-policy environment data and the actor (policy) is trained to maximize the Q-fun

Direct Preference-based Policy Optimization without Reward Modeling

Autor: An, Gaon, Lee, Junhyeok, Zuo, Xingdong, Kosaka, Norio, Kim, Kyung-Min, Song, Hyun Oh

Preference-based reinforcement learning (PbRL) is an approach that enables RL agents to learn from preference, which is particularly useful when formulating a reward function is challenging. Existing PbRL methods generally involve a two-step procedur

Pivotal Role of Language Modeling in Recommender Systems: Enriching Task-specific and Task-agnostic Representation Learning

Autor: Shin, Kyuyong, Kwak, Hanock, Kim, Wonjae, Jeong, Jisu, Jung, Seungjae, Kim, Kyung-Min, Ha, Jung-Woo, Lee, Sang-Woo

Recent studies have proposed unified user modeling frameworks that leverage user behavior data from various applications. Many of them benefit from utilizing users' behavior sequences as plain texts, representing rich information in any domain or sys

Deformable Graph Transformer

Autor: Park, Jinyoung, Yun, Seongjun, Park, Hyeonjin, Kang, Jaewoo, Jeong, Jisu, Kim, Kyung-Min, Ha, Jung-woo, Kim, Hyunwoo J.

Transformer-based models have recently shown success in representation learning on graph-structured data beyond natural language processing and computer vision. However, the success is limited to small-scale graphs due to the drawbacks of full dot-pr
