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 ``` [^1]: Formal et al., [SPLADE: Sparse Lexical and Expansion Model for First Stage Ranking](https://dl.acm.org/doi/abs/10.1145/3404835.3463098)
