# ColBERT-X for English-Russian CLIR using Translate-Distill

## Model Description

Translate-Distill is a training technique that produces state-of-the-art CLIR dense retrieval model through translation and distillation.
`plaidx-large-rus-tdist-t53b-engeng` is trained with KL-Divergence from the t53b MonoT5 reranker inferenced on 
English MS MARCO training queries and English passages. 

### Teacher Models:

- `t53b`: [`castorini/monot5-3b-msmarco-10k`](https://huggingface.co/castorini/monot5-3b-msmarco-10k)
- `mt5xxl`: [`unicamp-dl/mt5-13b-mmarco-100k`](https://huggingface.co/unicamp-dl/mt5-13b-mmarco-100k)

### Training Parameters

- learning rate: 5e-6
- update steps: 200,000
- nway (number of passages per query): 6 (randomly selected from 50)
- per device batch size (number of query-passage set): 8
- training GPU: 8 NVIDIA V100 with 32 GB memory

## Usage

To properly load ColBERT-X models from Huggingface Hub, please use the following version of PLAID-X. 
```bash
pip install git+https://github.com/hltcoe/ColBERT-X.git@plaid-x
```

Following code snippet loads the model through Huggingface API. 
```python
from colbert.modeling.checkpoint import Checkpoint
from colbert.infra import ColBERTConfig

Checkpoint('plaidx-large-rus-tdist-t53b-engeng', colbert_config=ColBERTConfig())
```
