InferAligner: Inference-Time Alignment for Harmlessness through Cross-Model Guidance

1 code implementation20 Jan 2024 Pengyu Wang, Dong Zhang, Linyang Li, Chenkun Tan, Xinghao Wang, Ke Ren, Botian Jiang, Xipeng Qiu

With the rapid development of large language models (LLMs), they are not only used as general-purpose AI assistants but are also customized through further fine-tuning to meet the requirements of different applications.

Watermarking LLMs with Weight Quantization

1 code implementation17 Oct 2023 Linyang Li, Botian Jiang, Pengyu Wang, Ke Ren, Hang Yan, Xipeng Qiu

Abuse of large language models reveals high risks as large language models are being deployed at an astonishing speed.

PerturbScore: Connecting Discrete and Continuous Perturbations in NLP

1 code implementation13 Oct 2023 Linyang Li, Ke Ren, Yunfan Shao, Pengyu Wang, Xipeng Qiu

Through experimental results, we find that we can build a connection between discrete and continuous perturbations and use the proposed PerturbScore to learn such correlation, surpassing previous methods used in discrete perturbation measuring.

Origin Tracing and Detecting of LLMs

no code implementations27 Apr 2023 Linyang Li, Pengyu Wang, Ke Ren, Tianxiang Sun, Xipeng Qiu

The extraordinary performance of large language models (LLMs) heightens the importance of detecting whether the context is generated by an AI system.

Kidney Exchange with Inhomogeneous Edge Existence Uncertainty

no code implementations7 Jul 2020 Hoda Bidkhori, John P. Dickerson, Duncan C. McElfresh, Ke Ren

To the best of our knowledge, the state-of-the-art approaches are only tractable when failure probabilities are identical.

A Robust AUC Maximization Framework with Simultaneous Outlier Detection and Feature Selection for Positive-Unlabeled Classification

no code implementations18 Mar 2018 Ke Ren, Haichuan Yang, Yu Zhao, Mingshan Xue, Hongyu Miao, Shuai Huang, Ji Liu

The positive-unlabeled (PU) classification is a common scenario in real-world applications such as healthcare, text classification, and bioinformatics, in which we only observe a few samples labeled as "positive" together with a large volume of "unlabeled" samples that may contain both positive and negative samples.
