| # Lightning IR SPLADE |
|
|
| This model is a SPLADE[^1] model fine-tuned using [Lightning IR](https://github.com/webis-de/lightning-ir). |
|
|
| See the [Lightning IR Model Zoo](https://webis-de.github.io/lightning-ir/models.html) for a comparison with other models. |
|
|
| ## Reproduction |
|
|
| To reproduce the model training, install Lightning IR and run the following command using the [fine-tune.yaml](./configs/fine-tune.yaml) configuration file: |
|
|
| ```bash |
| lightning-ir fit --config fine-tune.yaml |
| ``` |
|
|
| To index MS~MARCO passages, use the following command and the [index.yaml](./configs/index.yaml) configuration file: |
|
|
| ```bash |
| lightning-ir index --config index.yaml |
| ``` |
|
|
| After indexing, to evaluate the model on TREC Deep Learning 2019 and 2020, use the following command and the [search.yaml](./configs/search.yaml) configuration file: |
|
|
| ```bash |
| lightning-ir search --config search.yaml |
| ``` |
