About ANDlab
Since March 2021, ANDlab has been dedicated to uncovering meaningful insights from diverse real-world data. Our mission is to advance the frontiers of artificial intelligence by developing innovative methodologies in big data analytics, natural language processing (NLP), and information extraction. Our research spans a wide spectrum of domains, combining cutting-edge AI techniques with interdisciplinary applications. By leveraging state-of-the-art models and scalable data-driven approaches, we aim to address complex challenges in fields such as healthcare, economics, sociology, and industry.
Our team consists of researchers with strong expertise in modern AI paradigms, including large language models (LLMs), knowledge-augmented systems, and privacy-preserving learning. We actively explore emerging directions such as agentic AI, multimodal intelligence, and physical AI, while also contributing to foundational areas like information retrieval, knowledge graphs, and retrieval-augmented generation (RAG). At ANDlab, we believe in bridging theory and real-world impact. Our research focuses not only on advancing algorithms but also on enabling AI transformation (AIx) across industries, from healthcare and finance to technology and large-scale systems.
We are always looking for motivated and curious researchers who are passionate about NLP, data analytics, and the future of AI. If you are eager to tackle challenging problems and create meaningful impact through data and intelligence, we warmly welcome you to join ANDlab.
ANDlab은 2021년 3월부터 현재까지, 일상 속 다양한 실제 데이터를 기반으로 의미 있는 정보를 해석하고, 인공지능 기술의 새로운 가능성을 탐구해온 연구팀입니다. 우리는 빅데이터 분석, 자연어처리(NLP), 정보 추출 등 다양한 분석 기법을 통해 데이터로부터 가치 있는 인사이트를 도출하는 것을 목표로 합니다. 우리 연구실은 최신 인공지능 모델과 데이터 기반 분석 방법론을 바탕으로, 컴퓨터과학뿐만 아니라 의학, 경제학, 사회학, 산업 등 다양한 분야에서 융합 연구를 수행하며 의미 있는 연구 성과를 창출하고 있습니다.
특히, 대규모 언어모델(LLM), 지식 기반 자연어처리, 프라이버시 보호 학습과 같은 핵심 기술을 중심으로, 정보검색, 지식그래프, 질의응답 시스템, Retrieval-Augmented Generation (RAG) 등 기초 및 응용 연구를 폭넓게 진행하고 있습니다. 더 나아가, Agentic AI, 멀티모달 AI, 피지컬 AI 등 차세대 인공지능 패러다임에도 적극적으로 도전하고 있습니다. ANDlab은 이론적 연구를 넘어 실제 사회와 산업에 적용 가능한 AI 기술 개발을 지향합니다. 의료, 금융, 산업 기술 등 다양한 영역에서 AI 전환(AIx)을 실현하며, 확장 가능하고 신뢰할 수 있는 데이터 기반 시스템을 구축하는 데 집중하고 있습니다.
자연어처리와 데이터 분석, 그리고 인공지능의 미래에 깊은 관심과 열정을 가진 연구자 여러분을 환영합니다. 도전적인 문제를 해결하고, 데이터와 AI를 통해 사회에 기여하고자 하는 분이라면 ANDlab에서 함께 성장할 수 있기를 기대합니다.
