# Model description

A Fusion in Decoder(FiD) model based on BART for the [KILT-ELI5](https://github.com/facebookresearch/KILT) task.

The FiD model was in introduced in the paper 'Leveraging Passage Retrieval with Generative Models for Open Domain Question Answering'.

This model has been initialized with [facebook/bart-large](https://huggingface.co/facebook/bart-large).

This model was trained with the KILT-ELI5 questions and supporting passages obtained from a ColBERT index of the 2019/08/01 Wikipedia dump.

## Intended uses & limitations

You can use this raw model for the generative question answering task. Biases associated with the pre-existing language model that we used, facebook/bart-large, may be present in our fine-tuned model.

## Usage

You can use this model directly with the [PrimeQA](https://github.com/primeqa/primeqa)'s [Generative FiD Reader](https://github.com/primeqa/primeqa/tree/primeqa-fid/primeqa/pipelines#readme).
