# Dataset Card for "open-web-math-minhash"

An attempt at a _"high quality sample"_ of `open-web-math/open-web-math` by aggressively applying `minhash` from text-dedup. The result is 1.82M rows down from the original 6M:

```
DatasetDict({
    train: Dataset({
        features: ['url', 'text', 'date', 'metadata'],
        num_rows: 1820241
    })
})
```

## Usage

Unless you need the metadata, load the `text-only` config which is only 1.4 GB/5 shards:

```python
from datasets import load_dataset

dataset_config = "text-only"
dataset = load_dataset("BEE-spoke-data/open-web-math-minhash", dataset_config)
```

## making of

On a high-RAM colab TPU (40 cores)

```python
from pathlib import Path
from tqdm.auto import tqdm

ds_name = "open-web-math/open-web-math"
dataset_config = "default"
data_split = 'train'
text_column = 'text'

out_dir = Path(f"output/minhash/{ds_short_name}/{data_split}")
!mkdir -p $out_dir


!python -m text_dedup.minhash \
  --path $ds_name \
  --name $dataset_config \
  --split $data_split \
  --cache_dir "./cache" \
  --output $out_dir \
  --column $text_column \
  --ngram 5 --threshold 0.5 \
  --hash_func xxh3 --hash_bits 16 --num_perm 64 \
  --batch_size 10000

print(f"output dir is:\n\t{out_dir}")
!ls $out_dir
```
