SmartTutor: AI-Powered Educational System
Developed SmartTutor, an AI-powered intelligent tutoring system built on the Mastery-Conditioned Constrained Policy Optimization (MC-CPO) framework with Bayesian Knowledge Tracing. The system incorporates pedagogical safety constraints to prevent reward hacking in educational reinforcement learning, ensuring genuine learning outcomes over engagement manipulation.
