Improving the Robustness of Large Language Models via Consistency Alignment

no code implementations21 Mar 2024 Yukun Zhao, Lingyong Yan, Weiwei Sun, Guoliang Xing, Shuaiqiang Wang, Chong Meng, Zhicong Cheng, Zhaochun Ren, Dawei Yin

The training process is accomplished by self-rewards inferred from the trained model at the first stage without referring to external human preference resources.

Automating psychological hypothesis generation with AI: when large language models meet causal graph

no code implementations22 Feb 2024 Song Tong, Kai Mao, Zhen Huang, Yukun Zhao, Kaiping Peng

Leveraging the synergy between causal knowledge graphs and a large language model (LLM), our study introduces a groundbreaking approach for computational hypothesis generation in psychology.

MobileARLoc: On-device Robust Absolute Localisation for Pervasive Markerless Mobile AR

no code implementations21 Jan 2024 Changkun Liu, Yukun Zhao, Tristan Braud

To address APR accuracy and reduce VIO drift, MobileARLoc creates a feedback loop where VIO pose estimations refine the APR predictions.

Knowing What LLMs DO NOT Know: A Simple Yet Effective Self-Detection Method

no code implementations27 Oct 2023 Yukun Zhao, Lingyong Yan, Weiwei Sun, Guoliang Xing, Chong Meng, Shuaiqiang Wang, Zhicong Cheng, Zhaochun Ren, Dawei Yin

In this paper, we propose a novel self-detection method to detect which questions that a LLM does not know that are prone to generate nonfactual results.

Imitation Learning from Purified Demonstrations

1 code implementation11 Oct 2023 Yunke Wang, Minjing Dong, Yukun Zhao, Bo Du, Chang Xu

In the first step, we apply a forward diffusion process to smooth potential noises in imperfect demonstrations by introducing additional noise.

KS-APR: Keyframe Selection for Robust Absolute Pose Regression

no code implementations10 Aug 2023 Changkun Liu, Yukun Zhao, Tristan Braud

However, APR methods tend to yield significant inaccuracies for input images that are too distant from the training set.

Feature-Level Debiased Natural Language Understanding

1 code implementation11 Dec 2022 Yougang Lyu, Piji Li, Yechang Yang, Maarten de Rijke, Pengjie Ren, Yukun Zhao, Dawei Yin, Zhaochun Ren

We also propose a dynamic negative sampling strategy to capture the dynamic influence of biases by employing a bias-only model to dynamically select the most similar biased negative samples.
