Papers with reference-free evaluator
Designing Precise and Robust Dialogue Response Evaluators (2020.acl-main)
Copied to clipboard
| Challenge: | Existing automated dialogue response evaluators have only moderate correlation with human judgement and are not robust. |
| Approach: | They propose to build a reference-free dialogue response evaluator that exploits the power of semi-supervised training and pretrained (masked) language models. |
| Outcome: | The proposed model achieves strong correlation with human judgement and generalizes robustly to diverse responses and corpora. |

Yuxuan Liu, Tianchi Yang, Shaohan Huang, Zihan Zhang, Haizhen Huang, Furu Wei, Weiwei Deng, Feng Sun, Qi Zhang
| Challenge: | Existing models for large language models lack the ability to calibrate their outputs towards human preference. |
| Approach: | They propose a multi-stage, gradient-free approach to calibrate an LLM-based evaluator toward human preference. |
| Outcome: | The proposed approach improves correlation with expert evaluation on multiple text quality evaluation datasets. |
Harnessing Black-Box Control to Boost Commonsense in LM’s Generation (2023.emnlp-main)
Copied to clipboard
| Challenge: | Recent years have seen remarkable progress in massively Pre-Trained Language Models such as GPT-3 . however, their generated outputs lack commonsense at times . |
| Approach: | They propose a framework that steers a frozen Pre-Trained Language Model towards more commonsense generation by training an auxiliary model. |
| Outcome: | The proposed framework produces plausible outputs that incorporate concepts in a meaningful way. |
