Tree-Structured Non-Autoregressive Decoding for Sequence-to-Sequence Text Generation (2025.findings-emnlp)
Copied to clipboard
| Challenge: | Autoregressive Transformers suffer from high inference latency due to sequential token generation. |
| Approach: | They propose a tree-structured non-autoregressive decoding paradigm that bridges autoregressive and non-automatic decoding. |
| Outcome: | The proposed paradigm outperforms autoregressive and non-autoregressive decoding in machine translation and paraphrase generation. |
Retrospex: Language Agent Meets Offline Reinforcement Learning Critic (2024.emnlp-main)
Copied to clipboard
| Challenge: | Existing LLM agent frameworks do not fully utilize past experiences for improvement. |
| Approach: | They propose a LLM-based agent framework called Retrospex that analyzes past experiences in depth to improve existing agent frameworks. |
| Outcome: | The proposed framework analyzes past experiences in ScienceWorld, ALFWorld and Webshop environments, demonstrating its advantages over baselines. |
