Why Fine-Tuning Encourages Hallucinations and How to Fix It
★★★★★
significance 3/5
The paper investigates how supervised fine-tuning (SFT) can trigger hallucinations by causing knowledge degradation from the pre-training phase. The authors propose a self-distillation-based SFT method and parameter freezing to mitigate these errors and preserve factual accuracy.
Why it matters
Addressing the trade-off between specialized fine-tuning and factual retention is critical for building reliable, production-ready agentic systems.
