Stumbling Blocks: Stress Testing the Robustness of Machine-Generated Text Detectors Under Attacks

1 code implementation18 Feb 2024 Yichen Wang, Shangbin Feng, Abe Bohan Hou, Xiao Pu, Chao Shen, Xiaoming Liu, Yulia Tsvetkov, Tianxing He

Our experiments reveal that almost none of the existing detectors remain robust under all the attacks, and all detectors exhibit different loopholes.

LLM-based NLG Evaluation: Current Status and Challenges

no code implementations2 Feb 2024 Mingqi Gao, Xinyu Hu, Jie Ruan, Xiao Pu, Xiaojun Wan

Evaluating natural language generation (NLG) is a vital but challenging problem in artificial intelligence.

On the Zero-Shot Generalization of Machine-Generated Text Detectors

no code implementations8 Oct 2023 Xiao Pu, Jingyu Zhang, Xiaochuang Han, Yulia Tsvetkov, Tianxing He

The rampant proliferation of large language models, fluent enough to generate text indistinguishable from human-written language, gives unprecedented importance to the detection of machine-generated text.

PRO-Face S: Privacy-preserving Reversible Obfuscation of Face Images via Secure Flow

no code implementations18 Jul 2023 Lin Yuan, Kai Liang, Xiao Pu, Yan Zhang, Jiaxu Leng, Tao Wu, Nannan Wang, Xinbo Gao

This paper proposes a novel paradigm for facial privacy protection that unifies multiple characteristics including anonymity, diversity, reversibility and security within a single lightweight framework.

Is Summary Useful or Not? An Extrinsic Human Evaluation of Text Summaries on Downstream Tasks

no code implementations24 May 2023 Xiao Pu, Mingqi Gao, Xiaojun Wan

The results show that summaries generated by fine-tuned models lead to higher consistency in usefulness across all three tasks, as rankings of fine-tuned summarization systems are close across downstream tasks according to the proposed extrinsic metrics.

Contextual Learning in Fourier Complex Field for VHR Remote Sensing Images

1 code implementation28 Oct 2022 Yan Zhang, Xiyuan Gao, Qingyan Duan, Jiaxu Leng, Xiao Pu, Xinbo Gao

By stacking various layers of CSA blocks, we propose the Fourier Complex Transformer (FCT) model to learn global contextual information from VHR aerial images following the hierarchical manners.

Integrating Weakly Supervised Word Sense Disambiguation into Neural Machine Translation

1 code implementation TACL 2018 Xiao Pu, Nikolaos Pappas, James Henderson, Andrei Popescu-Belis

We show that the concatenation of these vectors, and the use of a sense selection mechanism based on the weighted average of sense vectors, outperforms several baselines including sense-aware ones.

Consistent Translation of Repeated Nouns using Syntactic and Semantic Cues

no code implementations EACL 2017 Xiao Pu, Laura Mascarell, Andrei Popescu-Belis

We compare the automatic post-editing of noun translations with the re-ranking of the translation hypotheses based on the classifiers{'} output, and also use these methods in combination.

A Simple Approach to Sparse Clustering

1 code implementation23 Feb 2016 Ery Arias-Castro, Xiao Pu

Consider the problem of sparse clustering, where it is assumed that only a subset of the features are useful for clustering purposes.
