Learn to improve dense retrieval reranking with test-time training for zero-resource settings, enhancing performance without costly supervised training
Action Steps
- Implement DART (Dense Adaptive Reranking at Test-time) using a dense retriever as the base model
- Configure the model for test-time training by adapting the reranking module
- Train the reranking module at test time using the target query and candidate passages
- Evaluate the performance of DART on benchmark datasets such as BEIR
- Compare the results with existing approaches like cross-encoders and BM25 reranking

Title: Test-Time Training for Zero-Resource Dense Retrieval Reranking
Abstract:
arXiv:2606.01070v1 Announce Type: cross Abstract: Dense retrievers excel at first-stage candidate generation but lack effective reranking in zero-resource settings. Existing approaches face a fundamental dilemma: cross-encoders deliver strong reranking quality but require costly supervised training and incur high latency, while unsupervised BM25 reranking consistently degrades dense retrieval performance on most of BEIR benchmarks. We propose DART (Dense Adaptive Reranking at Test-time), which r
