About

I am pursuing a combined M.S.–Ph.D. degree at the UNIST Graduate School of Artificial Intelligence, as a member of the IMIL Lab advised by Prof. Jooyeon Kim, after receiving a B.Sc. in Computer Science and Engineering from UNIST in 2022 (Cum Laude). My research is driven by one question: What are the fundamental limitations of machine learning, and how can we transcend them? We like to believe that machine learning solves many of our problems, yet in practice it often does not — the universal approximation theorem guarantees that neural networks can represent almost anything, but only under an unbounded budget, far removed from the situations we actually face. My goal is to draw a clear boundary of what is learnable under a limited budget: currently, I study the limitations of transformers in multi-step reasoning, combining theoretical analysis — such as learnability and circuit complexity under bounded resources — with empirical studies on reasoning benchmarks such as ARC-AGI, alongside a broader interest in world models. Previously, I worked on active learning, which led to a publication at AAAI 2024, and I am always open to research discussions and collaborations — feel free to reach out.

   Active learning is the process of iteratively selecting the most informative samples for labeling, with the goal of minimizing the number of labels required to achieve a desired level of performance. The classic active learning approaches focus on select sample one-by-one, that is not suitable for modern batch-style learning scenarios. In this work, we propose a novel approach that leverages efficient surrogate learners to guide the active learning process, enabling more effective and efficient sample selection in batch-style learning scenarios. The Gaussian surrogator proxy a movement of neural network for sampling them.
