| Challenge: | Speculative decoding (SD) is a training-free SD framework that orchestrates dynamic alternation combining serial dynamic drafting with parallel draft verification. |
| Approach: | They propose a serial and parallel intertwined speculative DEcoding framework that orchestrates dynamic alternation combining serial dynamic drafting and parallel draft verification. |
| Outcome: | The proposed framework accelerates inference while reducing the LLM usage costs. |
SCCD: A Session-based Dataset for Chinese Cyberbullying Detection (2025.coling-main)
Copied to clipboard
| Challenge: | Existing work on cyberbullying detection in Chinese is underdeveloped due to the lack of comprehensive and reliable datasets. |
| Approach: | They propose to use Chinese social media sessions to analyze Chinese cyberbullying content to improve the quality of annotations. |
| Outcome: | The proposed dataset shows that it performs better than existing methods on Weibo and a major social media platform. |
LLMs as World Models: Data-Driven and Human-Centered Pre-Event Simulation for Disaster Impact Assessment (2025.emnlp-main)
Copied to clipboard
| Challenge: | Recent advances in large language models (LLMs) show promise in simulating complex scenarios. |
| Approach: | They examine multiple LLMs to proactively estimate perceived earthquake impacts using multimodal datasets and multimodal imagery. |
| Outcome: | The framework generates Modified Mercalli Intensity (MMI) predictions at zip code and county scales using multimodal datasets. |
