Summary
👤
Senior🎓
Top SchoolNorio Kosaka is a research-focused machine learning engineer with eight years of experience applying reinforcement learning, recommendation evaluation, and NLP to industry-scale products at NAVER, LINE, and LY Corporation. He blends deep academic training—MSc in Machine Learning, advanced mathematics studies in London, and a forthcoming PhD in Informatics focused on computer vision and algebraic geometry—with hands-on engineering work building evaluation systems and inference engines. His internships at Panasonic and robotics-focused roles demonstrate a pattern of turning cutting-edge RL research into reproducible implementations and experiments. Based in Tokyo, he contributes code and technical writing on GitHub and maintains a personal site, signaling an active interest in open research and reproducible ML. A less obvious strength is his cross-disciplinary background from economics to advanced math, which informs pragmatic product thinking alongside rigorous theoretical work.
