JB is currently a PhD student at KAIST AI, advised by Jinwoo Shin. He delves into the true nature of deep learning through the lens of human cognitive systems, with a particular focus on how humans acquire, process, and apply knowledge. Before joining KAIST, JB led AI research for patent analysis and retrieval at Tanalysis. He obtained a Master’s Degree in Artificial Intelligence from Yonsei University, where he studied neural architectures and their foundations in formal language under the guidance of Yo-Sub Han. Prior to his journey into AI research, JB worked as a software engineer at Samsung Electronics.

Research Interests

• Designing Neural Architectures Modeled on Human Cognitive Systems
  Cognitive systems play a pivotal role in advancing neural architectures for perception, cognition and reasoning. Research aims to reach optimal neural architectures by aligning them with human cognition.

• Advancing Knowledge Access to Deep Models
  Despite the vast knowledge stored in deep models, accessing and leveraging those knowledge remains a challenge. Research encompasses broad spectrum of knowledge for neural models, from information retrieval to understanding dynamics of complex reasoning.

• Deep Learning for Language Acquisition with Minimal Data
  Large language models (LLMs) achieve language comprehension through vast amounts of data, whereas humans can acquire language from only a small amount of experience, known as the “poverty of the stimulus” argument. Research seeks deep learning methods that can effectively learn language with limited data by leveraging linguistic features.
