denseig 0.1.0
This package contains the required tools to run dense retriever explainability analysis using integrated gradients.
Requires Python: <4.0,>=3.8

# DenseIG

This repository contains the code for the DenseIG project.

## Introduction

DenseIG is a research project aimed at exploring explainability of the dense retriever techniques. The goal is to generate input attributions of dense retrievers using integrated gradients.
This project is aimed to explore the domain adapted model vs base model. However, you can taioler it to your needs.

## Installation via pip

To use the code in this repository, follow these steps:

1. Install via pypi

    ```bash
     pip install denseig
    ```

## Installation from source using poetry

1. Clone the repository:

    ```bash
    git clone https://github.com/your-username/DenseIG.git
    ```


2. Install the project using poetry install:

    ```bash
    poetry install
    ```

## Usage

To generate input attributions on BEIR datasets using the DenseIG models, and compare two models run the following command:
For now only two models are supported. This mainly serves the purpose of reproduction.

```bash
   python3 main.py "path_to_beir_data" "Non-adapted-dense-retriever" "adapted-dense-retriever"
```


To generate instance based attributions of any document-query pair, you should use the API. Only Dense Retriever models from SentenceTransformer framework is supported

```python
import torch 
from denseig.utils import generate_attributions_doc, generate_attributions_query, summarize_attributions
from sentence_transformers.util import dot_score
    
    
if __name__ == "__main__":
    query = ["What is python"]        
    doc = ["Python is an awsome tool"]
    device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
    # Only Dense Retriever models!
    model = "msmarco-distilbert-dot-v5"
    query_tokens, (q_attr, delta) = generate_attributions_query(query, doc, model, scoring_function = dot_score, device = device)
    q_attr  = summarize_attributions(q_attr)
    doc_tokens, (d_attr, delta) = generate_attributions_doc(query, doc, model, scoring_function = dot_score, device = device)
    doc_attr =  summarize_attributions(d_attr)
    print(q_attr)
```

      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
