ImpRIF: Stronger Implicit Reasoning Leads to Better Complex Instruction Following (2026.acl-long)
Copied to clipboard
| Challenge: | Experiments show that enhancing implicit reasoning capabilities can significantly improve complex instruction following in large language models. |
| Approach: | They propose a method to enhance LLMs’ understanding of implicit reasoning instructions by formalizing such instructions as verifiable reasoning graphs and fine-tuning with graph reasoning. |
| Outcome: | The proposed method outperforms existing models on five complex instruction following benchmarks and will be open-sourced in the near future. |
LCMA-SRT: Language-Conditional Mixture-of-Experts Adapters for Joint Multilingual Speech Recognition and Translation (2026.acl-long)
Copied to clipboard
| Challenge: | Existing hierarchical transducers suffer from negative transfer and unstable target-language generation, while training separate models for each direction is computationally prohibitive. |
| Approach: | They propose a hierarchical transducer with language-conditional Mixture-of-Experts adapters to improve multilingual joint automatic speech recognition and speech translation. |
| Outcome: | Experiments on Europarl-ST (9 languages, 72 directions) show that LCMA-SRT improves both ASR and ST within a single joint model, reducing average WER and improving BLEU and COMET over strong hierarchical transducer baselines. |
