# Dataset Card for DocVQA Dataset

## Dataset Description

- **Point of Contact from curators:** [Minesh Mathew](mailto:[email protected]), [Dimosthenis Karatzas]([email protected]), [C. V. Jawahar]([email protected])
- **Point of Contact Hugging Face:** [Pablo Montalvo](mailto:[email protected])

### Dataset Summary

DocVQA dataset is a document dataset introduced in Mathew et al. (2021) consisting of 50,000 questions defined on 12,000+ document images. 

### Usage

This dataset can be used with current releases of Hugging Face `datasets` library. 
Here is an example using a custom collator to bundle batches in a trainable way on the `train` split

```python

from datasets import load_dataset



docvqa_dataset = load_dataset("pixparse/docvqa-single-page", split="train"
)

collator_class = Collator()
loader = DataLoader(docvqa_dataset, batch_size=8, collate_fn=collator_class.collate_fn)
```

The loader can then be iterated on normally and yields image + question and answer samples. 

### Data Splits


#### Train
* 10194 images, 39463 questions and answers.

### Validation

* 1286 images, 5349 questions and answers.

### Test

* 1,287 images,  5,188 questions.
