I am an undergraduate student at Sungkyunkwan University interested in language models, retrieval-augmented generation, preference optimization,autonomous data agents. I use this blog to organize paper reviews, math notes, and implementation-oriented study logs.

Research Interests

  • Retrieval-augmented generation and semantic search
  • Reasoning agents for structured data analysis
  • Embedding models and contrastive learning
  • LLM alignment and preference optimization
  • Reinforcement Learning
  • Multimodal reasoning for planning and control
  • Vision-Language-Action (VLA) models and embodied AI

Currently Studying About

  • Foundation model architectures and pre-training
  • LLM reasoning, ReAct-style workflows, and verification
  • Machine learning fundamentals and mathematical intuition
  • Course notes from operating systems, networks, and ML

Background LLM은 수학 추론에 큰 진전을 보이고 있지만 여전히 논리적 / 계산 실수를 한다. 답은 맞추더라도 추론 과정이 그럴 듯 하게 틀리거나 아예 틀리는 경우가 빈번하다. 따라서 Language model의 풀이 step들을 채점해서 어디서 틀렸는지 알려줄 수 있는...
