Multimodal Needle in a Haystack: Benchmarking Long-Context Capability of Multimodal Large Language Models

NAACL 2025long

Multimodal Large Language Models (MLLMs) have shown significant promise in various applications, leading to broad interest from researchers and practitioners alike. However, a comprehensive evaluation of their long-context capabilities remains underexplored. To address these gaps, we introduce the M…

Probabilistic Conceptual Explainers: Trustworthy Conceptual Explanations for Vision Foundation Models

ICML 2024poster

Vision transformers (ViTs) have emerged as a significant area of focus, particularly for their capacity to be jointly trained with large language models and to serve as robust vision foundation models. Yet, the development of trustworthy explanation methods for ViTs has lagged, particularly in the c…

Variational Language Concepts for Interpreting Foundation Language Models

EMNLP 2024finding

Foundation Language Models (FLMs) such as BERT and its variants have achieved remarkable success in natural language processing. To date, the interpretability of FLMs has primarily relied on the attention weights in their self-attention layers. However, these attention weights only provide word-leve…
