# SymbolicRegressionQA

SymbolicRegressionQA (SRQA) is a multiple-choice visual question answering dataset introduced in
[Bayesian Adaptation Gym](https://arxiv.org/abs/2606.22188) (UAI 2026). Each question shows a plot of a
symbolic expression and asks which of four candidate formulas describes the relationship between the
variables.

## Splits

| Split | Examples |
| --- | --- |
| train | 10,000 |
| validation | 1,000 |
| test | 1,000 |

## Fields

| Field | Type | Description |
| --- | --- | --- |
| `image` | `Image` | 224x224 grayscale plot of the ground truth expression |
| `choices` | `list[str]` | Four candidate formulas, in the order they are presented |
| `label` | `str` | Letter of the correct choice, one of `A`, `B`, `C`, `D` |
| `sympy_reprs` | `list[str]` | SymPy representation of each of the four choices |
| `degrees` | `list[int]` | Polynomial degree of each of the four choices |
| `question_id` | `int` | Unique identifier within the split |

The correct answer is close to uniform over the four letters in every split.

## Usage

```python
from datasets import load_dataset

data = load_dataset("csamplawski/SymbolicRegressionQA", split="test")
```

The prompt used in the BAG experiments is built from `choices` as follows:

```
For the provided image of a plot, which of following formulas best describes the relationship between the variables? Output the letter of your choice only.
Choices:
A) <choices[0]>
B) <choices[1]>
C) <choices[2]>
D) <choices[3]>
```

See `bayesadapt/datasets/srqa.py` in [BayesAdapt](https://github.com/SRI-CSL/BayesAdapt) for the loader
used in the paper.
