# M2QA Adapter: QA Head for MAD-X+Domain Setup
This adapter is part of the M2QA publication to achieve language and domain transfer via adapters.  
📃 Paper: [https://aclanthology.org/2024.findings-emnlp.365/](https://aclanthology.org/2024.findings-emnlp.365/)  
🏗️ GitHub repo: [https://github.com/UKPLab/m2qa](https://github.com/UKPLab/m2qa)  
💾 Hugging Face Dataset: [https://huggingface.co/UKPLab/m2qa](https://huggingface.co/UKPLab/m2qa)  

**Important:** This adapter only works together with the MAD-X language adapters and the M2QA MAD-X-Domain adapters. This QA adapter was trained on the SQuAD v2 dataset.

This [adapter](https://adapterhub.ml) for the `xlm-roberta-base` model that was trained using the **[Adapters](https://github.com/Adapter-Hub/adapters)** library. For detailed training details see our paper or GitHub repository: [https://github.com/UKPLab/m2qa](https://github.com/UKPLab/m2qa). You can find the evaluation results for this adapter on the M2QA dataset in the GitHub repo and in the paper.


## Usage

First, install `adapters`:

```
pip install -U adapters
```

Now, the adapter can be loaded and activated like this:

```python
from adapters import AutoAdapterModel
from adapters.composition import Stack

model = AutoAdapterModel.from_pretrained("xlm-roberta-base")

# 1. Load language adapter
language_adapter_name = model.load_adapter("de/wiki@ukp") # MAD-X+Domain uses the MAD-X language adapter

# 2. Load domain adapter
domain_adapter_name = model.load_adapter("AdapterHub/m2qa-xlm-roberta-base-mad-x-domain-news")

# 3. Load QA head adapter
qa_adapter_name = model.load_adapter("AdapterHub/m2qa-xlm-roberta-base-mad-x-domain-qa-head")

# 4. Activate them via the adapter stack
model.active_adapters = Stack(language_adapter_name, domain_adapter_name, qa_adapter_name)
```
