Putting Captions to the Test: Evaluating Video Caption Quality through Multiple-Choice Question Answering
Apple Machine Learning Research · Published · 3 min read
In 30 seconds
- What happened
- Apple researchers introduced CapQuiz, a reference-free benchmark for evaluating video captions using multiple-choice questions instead of text matching against ground truth.
- Why it matters
- Engineers building or evaluating video captioning systems and visual language models need better metrics that handle the inherent variability in valid descriptions.
- Watch out
- CapQuiz requires human-verified questions and covers only 24 video domains; generalization to other domains or real-world deployment scalability remains unclear.
