PhD Researcher / Graduate Research Assistant, National Central University, Taiwan Sep 2025 - Present Gen AI / Multi-Agent Systems / Knowledge Graph / Neuro-Symbolic AI/Causal Inference/NLP ● Enterprise Knowledge Graph (KG): Developed a high-precision KG for manufacturing control plans and design parameters, enabling cross-document retrieval and zero-hallucination querying for industrial standards. ● Predictive Diagnostics: Integrated Bayesian Networks with KG and LLMs to infer potential impacts on yield and reliability by reasoning through historical event correlations. ● Intelligent KM Copilot: Engineered a personalized Knowledge Management system with long-term memory and automated SWOT analysis, proactively guiding users with "Golden Rules" based on behavior patterns. ● Neuro-Symbolic Reasoning: Built a logic-based framework to verify design rule compliance; combined qualitative historical insights from KG to assess risks in real-time manufacturing events. ● Conversational AI & Auto-Scripting: Implemented a Text-to-Script engine that automatically generates and confi gures testing scripts based on natural language user requirements. ● Multi-Agent Hierarchy: Designed a Multi-Agent system using hierarchical planning to decompose complex queries into sub-tasks, featuring autonomous tool-use and self-correction for unexpected edge cases.
