지능 최적화 및 강화학습 연구실

AI Cognition Optimization & Reinforcement Learning Lab

지능 최적화 및 강화학습 연구실 (AI-CORE Lab) 은 강화학습을 통한 차세대 지능형 시스템의 이론적 기반과 실용적 응용을 탐구합니다. 본 연구실에서는 강화학습을 통해 AI Agent가 스스로 지능을 최적화하며 새로운 환경에서도 적응할 수 있는 알고리즘 개발을 목표로 하며, 특히 대규모 언어모델이나, 로봇, 그리고 산업 현장에서의 실제 문제 해결에 적용할 수 있는 강화학습에 대한 연구를 진행하고 있습니다. 이러한 연구를 통해 설명 가능하고 신뢰할 수 있으며, 실생활 및 산업 현장에도 도움이 되는 차세대 인공지능을 만들어 가는 것을 목표로 합니다.

The AI Cognition Optimization with Reinforcement & Exploration (AI-CORE) Lab explores both the theoretical foundations and practical applications of next-generation intelligent systems through reinforcement learning. Our goal is to develop algorithms that enable AI agents to optimize their own intelligence and adapt to new environments using reinforcement learning. In particular, we conduct research on reinforcement learning that can be applied to large language models, robotics, and real-world industrial problems. Through this research, AI-CORE Lab aims to create next-generation AI that is explainable, trustworthy, and beneficial for both everyday life and industrial applications.
