ASE 2026 – Munich

My supervisor Dr. Jinahn Kim presented our paper, “When Knowledge Changes: Metamorphic Testing of RAG Systems with Mutations,” at ASE 2026.

---

In this work, we introduce a metamorphic testing framework to evaluate how Retrieval-Augmented Generation (RAG) systems behave as their underlying document corpora evolve. Using 11 mutation operators across five datasets and over 28k mutants, we uncover faults that traditional evaluation metrics can miss.

Great experience in Munich!
