Bridging Selective Perturbation to Fine-tuned Contrastive Learning Detector would be Better](https://md.research.elamur.ai/free/en/papers/liu-2024-does-detectgpt-fully-utilize-perturbation/)** *(2024 · 16 citations)* The paper tackles detection of machine-generated text (MGT) and addresses three weaknesses of DetectGPT. Its random perturbations can inject noise. It reduces perturbation to a single probability-difference score. Its threshold-based logit regression generalizes poorly and fails on single or small-batch inputs.

Real deployments, however, involve dialogues where users push back. The authors define multi-turn calibration : confidence must match accuracy at every turn, given the conversation history. They introduce ECE@T , which… ## Co-authors here 6 co-authors with a page, the most papers together first. - [Chao Shen](https://md.research.elamur.ai/free/en/authors/chao-shen/) ×2 - [Xiaoming Liu](https://md.research.elamur.ai/free/en/authors/xiaoming-liu/) ×2 - [Zhaohan Zhang](https://md.research.elamur.ai/free/en/authors/zhaohan-zhang/) ×2 - [Ioannis Patras](https://md.research.elamur.ai/free/en/authors/ioannis-patras/) - [Yichen Wang](https://md.research.elamur.ai/free/en/authors/yichen-wang/) - [Ziquan Liu](https://md.research.elamur.ai/free/en/authors/ziquan-liu/) ## Venues Where their works here were published, the most works first, with the editions of those that have a page. - [Annual Meeting of the Association for Computational Linguistics (ACL)](https://md.research.elamur.ai/free/en/venues/acl/) ×2: [ACL 2026](https://md.research.elamur.ai/free/en/venues/acl/2026/), [ACL 2024](https://md.research.elamur.ai/free/en/venues/acl/2024/) ## Cited by Papers of our library cite their works 14 times (of the 149,439 papers whose bibliographies we read); [6 citing papers with a page here →](https://md.research.elamur.ai/free/en/authors/chengzhengxu-li/cited-by/).
