Dataset Creation

Curation Rationale

The Pix2Tex Dataset was created to address the need for diverse, high-quality datasets for training Vision-Language Models (VLMs) that can extract LaTeX from mathematical formula images. By including both printed and handwritten formulas, the dataset provides a robust benchmark for real-world applications.

Source Data

Data Collection and Processing

The dataset was created by combining two existing datasets:

  • One dataset containing printed formula images with their LaTeX annotations.
  • Another dataset containing handwritten formula images with their LaTeX annotations.

Both datasets were preprocessed to ensure consistency in column naming and annotation quality. The resulting dataset was split into training, validation, and test sets.

Who are the source data producers?

The source data was collected from publicly available datasets and curated for the specific purpose of LaTeX extraction tasks.


Bias, Risks, and Limitations

Risks and Limitations

  • The dataset includes a mix of printed and handwritten formulas, which might introduce variability in performance for models trained solely on one type of input.
  • The handwritten formulas may contain noise due to variations in handwriting styles, potentially challenging OCR tasks.

Recommendations

Users are advised to preprocess the dataset and evaluate models on both printed and handwritten subsets to better understand their performance across different input types.
