BERT-based QA models assessed for reliability; RoBERTa shows most stability

A new study published on arXiv evaluates the reliability of several BERT-based models, including RoBERTa, ALBERT, and DistilBERT, when applied to question-answering tasks. Researchers assessed model stability by introducing variations through Monte Carlo Dropout and input paraphrasing on the SQuAD and QuAC datasets. The findings indicate that RoBERTa is the most reliable among the tested models, while ALBERT and DistilBERT showed significant inconsistencies. The study also confirmed that Monte Carlo Dropout is an effective metric for gauging reliability without disrupting inference. AI

IMPACT Highlights the need for reliability assessment beyond accuracy in QA models for real-world deployment.
