Beyond the Score: Uncertainty-Calibrated LLMs for Automated Essay Assessment (2025.emnlp-main)
Copied to clipboard
| Challenge: | Automated Essay Scoring (AES) systems attain near–human agreement on some public benchmarks, but real-world adoption is limited. |
| Approach: | They propose a distribution-free wrapper that equips any classifier with set-valued outputs enjoying formal coverage guarantees. |
| Outcome: | The proposed model achieves coverage targets while keeping prediction sets compact. |

| Challenge: | ECHO-LLaMA transforms LLa MA models into shared KV caching across certain layers, significantly reducing KV computational complexity while maintaining or improving language performance. |
| Approach: | They propose an efficient LLaMA architecture that transforms LLama models into shared KV caching across certain layers, reducing computational complexity while maintaining or improving language performance. |
| Outcome: | ECHO-LLaMA achieves up to 77% higher token-per-second throughput during training, up to 16% higher Model FLOPs Utilization (MFU) and up to 14% lower loss when trained on an equal number of tokens. |
