Adaptive Collaboration Strategy for LLMs in Medical Decision Making

1 code implementation22 Apr 2024 Yubin Kim, Chanwoo Park, Hyewon Jeong, Yik Siu Chan, Xuhai Xu, Daniel McDuff, Cynthia Breazeal, Hae Won Park

Our novel framework, Medical Decision-making Agents (MDAgents) aims to address this gap by automatically assigning the effective collaboration structure for LLMs.

Do LLM Agents Have Regret? A Case Study in Online Learning and Games

no code implementations25 Mar 2024 Chanwoo Park, Xiangyu Liu, Asuman Ozdaglar, Kaiqing Zhang

To better understand the limits of LLM agents in these interactive environments, we propose to study their interactions in benchmark decision-making settings in online learning and game theory, through the performance metric of \emph{regret}.

Promptable Behaviors: Personalizing Multi-Objective Rewards from Human Preferences

no code implementations14 Dec 2023 Minyoung Hwang, Luca Weihs, Chanwoo Park, Kimin Lee, Aniruddha Kembhavi, Kiana Ehsani

Customizing robotic behaviors to be aligned with diverse human preferences is an underexplored challenge in the field of embodied AI.

Multi-Player Zero-Sum Markov Games with Networked Separable Interactions

no code implementations NeurIPS 2023 Chanwoo Park, Kaiqing Zhang, Asuman Ozdaglar

We study a new class of Markov games, \emph(multi-player) zero-sum Markov Games} with \emph{Networked separable interactions} (zero-sum NMGs), to model the local interaction structure in non-cooperative multi-agent sequential decision-making.

A Unified Analysis of Mixed Sample Data Augmentation: A Loss Function Perspective

1 code implementation21 Aug 2022 Chanwoo Park, Sangdoo Yun, Sanghyuk Chun

Our theoretical results show that regardless of the choice of the mixing strategy, MSDA behaves as a pixel-level regularization of the underlying training loss and a regularization of the first layer parameters.

REST: Performance Improvement of a Black Box Model via RL-based Spatial Transformation

no code implementations16 Feb 2020 Jae Myung Kim, Hyungjin Kim, Chanwoo Park, Jungwoo Lee

Our work aims to improve the robustness by adding a REST module in front of any black boxes and training only the REST module without retraining the original black box model in an end-to-end manner, i. e. we try to convert the real-world data into training distribution which the performance of the black-box model is best suited for.

Sampling-based Bayesian Inference with gradient uncertainty

no code implementations8 Dec 2018 Chanwoo Park, Jae Myung Kim, Seok Hyeon Ha, Jungwoo Lee

In this paper, we show that predictive uncertainty can be efficiently estimated when we incorporate the concept of gradients uncertainty into posterior sampling.
