CORD: Balancing COnsistency and Rank Distillation for Robust Retrieval-Augmented Generation (2025.naacl-short)
Copied to clipboard
| Challenge: | Existing methods to ground large language models fail to adequately attend to all contexts . position bias is hindered by retrieval-augmented generation, which requires constant attention . |
| Approach: | They propose to augment and distill training instances with their perturbed positions to encourage consistent predictions . they also propose to balance COnsistency and Rank Distillation by combining noise-controlled perturbations with augmentation and distillation. |
| Outcome: | The proposed method outperforms existing methods in diverse RAG benchmarks. |
Inference Scaling for Bridging Retrieval and Augmented Generation (2025.findings-naacl)
Copied to clipboard
| Challenge: | Existing work observed the generator bias, such that improving the retrieval results may negatively affect the outcome. |
| Approach: | They propose to use inference scaling to aggregate inference calls from the permuted order of retrieved contexts to create a new ranking. |
| Outcome: | The proposed approach improves ROUGE-L on MS MARCO and EM on HotpotQA benchmarks by 7 points. |
STUN: Structured-Then-Unstructured Pruning for Scalable MoE Pruning (2025.acl-long)
Copied to clipboard
| Challenge: | Mixture-of-experts (MoEs) have been adopted for reducing inference costs by sparsely activating experts in large language models (LLMs). |
| Approach: | They propose a structured-then-unstructured approach outperforming both of structured and unstructured pruning for MoEs. |
| Outcome: | The proposed approach outperforms both of structured and unstructured pruning, especially for MoEs with hundreds of experts. |
