ELV-Halluc: Benchmarking Semantic Aggregation Hallucinations in Video Understanding

CVPR 2026

We revisit video hallucination in multimodal large language models (Video-MLLMs) from a semantic aggregation perspective. While prior work attributes hallucinations to language priors, missing frames, or visual encoder biases, these explanations overlook errors arising during the aggregation of corr

EVA: Efficient Reinforcement Learning for End-to-End Video Agent

CVPR 2026

Video understanding with multimodal large language models (MLLMs) remains challenging due to the long token sequences of videos, which contain extensive temporal dependencies and redundant frames.Existing approaches typically treat MLLMs as passive recognizers, processing entire videos or uniformly

SALAD-Bench: A Hierarchical and Comprehensive Safety Benchmark for Large Language Models

ACL 2024findings

In the rapidly evolving landscape of Large Language Models (LLMs), ensuring robust safety measures is paramount. To meet this crucial need, we propose SALAD-Bench, a safety benchmark specifically designed for evaluating LLMs, attack, and defense methods. Distinguished by its breadth, SALAD-Bench tra…
