Leveraging Fuzzy Logic Towards More Explainable Reinforcement Learning-Induced Pedagogical Policies on Intelligent Tutoring Systems

Presented at the 2023 IEEE International Conference on Fuzzy Systems (FUZZ).

By: J. Hostetter n, M. Abdelshiheed n, T. Barnes n & M. Chi n

Event: 2023 IEEE International Conference on Fuzzy Systems (FUZZ)

TL;DR: F fuzzy logic is applied to distill knowledge from Deep RL-induced policies into interpretable IF-THEN Fuzzy Logic Controller (FLC) rules, showing that these FLC policies significantly outperform expert policy and student decisions, demonstrating the effectiveness of this approach.
