Great work and sharing our NaturalBench

[linzhiqiu]

I am Zhiqiu Lin, a final-year PhD student at Carnegie Mellon University working on the evaluation of vision-language models, and we found your work quite inspiring!

I also wanted to share NaturalBench (NeurIPS'24 D&B), a collaborative project between CMU and the University of Washington, which might interest you:

NaturalBench (https://linzhiqiu.github.io/papers/naturalbench/) is a vision-centric benchmark that challenges vision-language models with pairs of simple questions about natural imagery. Unlike prior VQA benchmarks (like MME and ScienceQA), which blind language models (e.g., GPT-3.5) can solve, NaturalBench ensures such shortcuts won’t work. We evaluated 53 state-of-the-art models, and even top models like GPT-4o and Qwen2-VL fall 50%-70% short of human accuracy (90%+), revealing significant room for improvement.

We also found that current models show strong answer biases, such as favoring “Yes” over “No” regardless of the input. Correcting these biases can boost performance by 2-3x, even for GPT-4o, making NaturalBench a valuable testbed for future debiasing techniques.
