# mlx7-two-tower-data

This repository contains datasets used for training Two-Tower (Dual Encoder) models for document retrieval.

## Dataset Description

The datasets provided here are structured for training dual encoder models with various sampling strategies:

- **classic_triplets**: 48.2 MB
- **intra_query_neg**: 47.6 MB
- **multi_pos_multi_neg**: 126.5 MB

### Dataset Details

- **classic_triplets.parquet**: Standard triplet format with (query, positive_document, negative_document)
- **intra_query_neg.parquet**: Negative examples selected from within the same query batch
- **multi_pos_multi_neg.parquet**: Multiple positive and negative examples per query

## Usage

```python
import pandas as pd

# Load a dataset
df = pd.read_parquet("classic_triplets.parquet")

# View the schema
print(df.columns)

# Example of working with the data
queries = df["q_text"].tolist()
positive_docs = df["d_pos_text"].tolist()
negative_docs = df["d_neg_text"].tolist()
```

## Data Source and Preparation

These datasets are derived from the MS MARCO passage retrieval dataset, processed to create effective training examples for two-tower models.

## Dataset Structure

The datasets follow a common schema with the following fields:
- `q_text`: Query text
- `d_pos_text`: Positive (relevant) document text
- `d_neg_text`: Negative (non-relevant) document text

Additional fields may be present in specific datasets.
