## Introduction
NutritionQA is a novel benchmark for understanding photos of nutrition labels, with practical applications like aiding users with visual impairments.
NutritionQA contains 50 photos of nutrition labels, each photo is paired with a descriptive question and a reasoning question (requires multi-hop reasoning).
The figure below shows that open VLMs perform poorly on NutritionQA, even after training on millions of images. Our [code-guided synthetic data generation system](https://github.com/allenai/pixmo-docs) can create targeted data (synthetic nutrition labels) to fine-tune VLMs, which achieves competitive performance with significantly less data.

## Evaluation
To compute the metrics, please use the following script:
```python
def score(question: str, target: str, prediction: str) -> bool:
prompt = f"""You are tasked with evaluating a model's prediction for a question-answering task. Your goal is to determine if the model's prediction is correct based on its meaning, not necessarily exact wording.
Here is the question that was asked:
<q>
{question}
</q>
The ground-truth answer to this question is:
<gt>
{target}
</gt>
The model's prediction for this question is:
<pred>
{prediction}
</pred>
To evaluate the model's prediction, follow these steps:
1. Carefully read the question, correct answer, and model's prediction.
2. Compare the meaning of the model's prediction to the correct answer, not just the exact wording.
3. Consider if the model's prediction accurately answers the question, even if it uses different phrasing or includes additional information.
4. Determine if any discrepancies between the prediction and correct answer are significant enough to consider the prediction incorrect.
5. For numerical answers, consider if the prediction is within a reasonable range (5%) of the correct answer.
Please answer with yes or no to indicate if the model's prediction is correct based on the question and correct answer provided.
