ReCaRe — Domain-Adapted Dense Retrievers (Table 4)

Fine-tuned dense retriever checkpoints for the ReCaRe benchmark (kasys/ReCaRe), reproducing the domain-adaptation results (Table 4) of the ReCaRe CIKM 2026 Resource paper. These let third parties reproduce the evaluation without re-running the (expensive) training phase.

Contents (20 checkpoints)

5 base models × 2 tasks (rat2rev, rev2rev) × 2 languages (en, ja), each in a subfolder named <model>_<task>_<lang>:

Base model	Tuning	Saved weights	Per-ckpt size
mdpr (castorini/mdpr-tied-pft-msmarco)	full FT	model.safetensors	~683 MB
mcontriever (facebook/mcontriever)	full FT	model.safetensors	~683 MB
me5-base (intfloat/multilingual-e5-base)	full FT	model.safetensors	~1.1 GB
bge-m3 (BAAI/bge-m3)	PEFT LoRA adapter	adapter_model.safetensors + adapter_config.json	~49 MB
jina-v3 (jinaai/jina-embeddings-v3)	native task-LoRA fine-tune	model.safetensors (full custom model)	~1.1 GB

Each subfolder also ships its tokenizer and a checkpoint_meta.json with the training hyperparameters (tuning_method, learning_rate, epochs, seed, temperature, output_alias, …).

Two save formats (see checkpoint_meta.json → tuning_method):

• bge-m3 uses a standard PEFT LoRA adapter, so only the adapter is saved (adapter_model.safetensors); load it on top of BAAI/bge-m3.
• jina-v3 fine-tunes Jina's built-in task LoRA and is saved as a full custom model via save_pretrained() (model.safetensors).
• mdpr / mcontriever / me5-base are full fine-tunes (model.safetensors).

Reproduction

The released code repo kasys-lab/ReCaRe fetches these into the layout its evaluation expects (results/dense_finetune/<model>/<task>_<lang>/best) and runs Phase 3 of scripts/run_domain_adaptation.sh (encode adapted corpus → evaluate on test → aggregate), so you can skip Phase 2 (training).
