SWE-QA: Can Language Models Answer Repository-level Code Questions? (2026.findings-acl)
Copied to clipboard
| Challenge: | Existing benchmarks for understanding and reasoning about entire soft-ware repositories focus on small, self-contained code snippets. |
| Approach: | They propose a repository-level code question answering benchmark to facilitate research on automated QA systems in real-world repositories. |
| Outcome: | The proposed benchmarks are designed to facilitate research on automated QA systems in real-world repositories. |
GlimpRouter: Efficient Collaborative Inference by Glimpsing One Token of Thoughts (2026.findings-acl)
Copied to clipboard
| Challenge: | Existing routing strategies rely on local token probabilities or post-hoc verification, introducing significant inference overhead. |
| Approach: | They propose a step-wise collaboration framework that generates only the first token of each reasoning step and routes it to a larger model only when initial token entropy exceeds a threshold. |
| Outcome: | The proposed approach reduces inference latency while preserving accuracy. |
Transplant Then Regenerate: A New Paradigm for Text Data Augmentation (2025.emnlp-main)
Copied to clipboard
| Challenge: | Data augmentation is a critical technique in deep learning. |
| Approach: | They propose a novel text augmentation paradigm leveraging large language models . they incorporate seed text into a context expanded by LLM and ask it to regenerate a variant based on the expanded context. |
| Outcome: | The proposed model generates high-quality and diverse augmented text with a transplant-then-regenerate approach. |
