Our research centers on neuro-symbolic algorithms, formal verification of neural networks, next-generation neural architectures & learning algorithms, and multi-agent reinforcement learning — which we apply to real-world domains such as sports data analytics and AI-driven program understanding & generation. Meet our team members, browse our publications, or visit Prof. Sang-Ki Ko's personal website for more details.

Research Areas

  • Neuro-Symbolic Algorithms — Combining symbolic, automata-theoretic methods with neural learning: regular expression synthesis from examples, regular language inference, descriptional complexity, and Simon’s congruence.
  • Formal Verification of Neural Networks — Safety and correctness verification of DNNs and spiking neural networks (SNNs) using automata-theoretic and model-checking techniques.
  • Next-Generation Neural Architectures & Learning — Spiking neural networks and biologically inspired learning algorithms such as STDP, with a focus on training efficiency and adversarial robustness.
  • Multi-Agent Reinforcement Learning — Reinforcement learning for multiple interacting agents, game-playing agents, and strategy optimization in dynamic, uncertain environments.
  • ML/AI Applications — Applying cutting-edge machine learning and AI to real-world domains, with two flagship areas: sports data analytics (player performance evaluation, multi-agent trajectory inference, formation analysis, strategy optimization) and AI-driven program understanding & generation (program repair, time complexity prediction, grammar-based test generation, LLM-based code analysis).
