Rigel metric improves image and video captioning evaluation

Researchers have developed Rigel, a new metric for evaluating image and video captioning systems that aims to better align with human judgments than existing methods. Rigel utilizes a self-distilled score adaptation approach, where an evaluation-specific scoring head is distilled from a large language model and then refined with human judgment data. This method avoids the limitations of large-vocabulary language models by focusing on task-aligned scoring. The effectiveness of Rigel was demonstrated using the newly constructed Vid-Lepus dataset, showing significant improvements over current state-of-the-art metrics on benchmarks like ActivityNet-Fact. AI

    Rigel: Self-Distilled Score Adaptation for Image and Video Captioning Evaluation

    Automatic evaluation of image and video captioning is essential for benchmarking multimodal systems, although standard evaluation metrics show limited alignment with human judgments. Recent approaches using large language models (LLMs), commonly referred to as LLM-as-a-Judge, hav…
