    Title: Robust and Context Faithful Language Understanding with (Large) Language Models

    Abstract: Large language models (LLMs) have achieved remarkable success in various language understanding tasks. However, their deployment in real world scenarios raises significant accountability concerns. In this talk, I will begin with the contextual faithfulness issue. LLMs often rely on biased parametric knowledge to make unfaithful predictions. I will present a causality driven approach aimed at mitigating entity bias to ensure context faithful NLU. Subsequently, I will introduce the robustness issue against unknown prediction shortcuts. I will demonstrate how to address the issue by proactively mitigating attention biases. Finally, I will outline potential future directions for advancing LLM accountability
