Abstract:
Large language models (LLMs) have shown remarkable potential in real-world applications. Despite their impressive capabilities, they can still produce errors in simple situations and behave in ways that are misaligned with human expectations, raising concerns about their reliability. As a result, ensuring their robustness has become a critical challenge. In this talk, I will explore key robustness issues across three aspects of LLMs: pure text-based LLMs, multimodal LLMs, and multilingual LLMs. Specifically, I will first introduce how position bias can hurt the understanding capabilities of LLMs and present a training-free solution to address this issue. Next, I will discuss position bias in the multimodal setting and introduce a Primal Visual Description (PVD) module that enhances robustness in multimodal understanding. Finally, I will examine the impact of language alignment on the robustness of multilingual LLMs.
