OpenEval: Benchmarking Chinese LLMs across Capability, Alignment and Safety

no code implementations18 Mar 2024 Chuang Liu, Linhao Yu, Jiaxuan Li, Renren Jin, Yufei Huang, Ling Shi, Junhui Zhang, Xinmeng Ji, Tingting Cui, Tao Liu, Jinwang Song, Hongying Zan, Sun Li, Deyi Xiong

In addition to these benchmarks, we have implemented a phased public evaluation and benchmark update strategy to ensure that OpenEval is in line with the development of Chinese LLMs or even able to provide cutting-edge benchmark datasets to guide the development of Chinese LLMs.

Privacy for Fairness: Information Obfuscation for Fair Representation Learning with Local Differential Privacy

no code implementations16 Feb 2024 Songjie Xie, Youlong Wu, Jiaxuan Li, Ming Ding, Khaled B. Letaief

Based on the proposed method, we further develop a variational representation encoding approach that simultaneously achieves fairness and LDP.

PACE: A Pragmatic Agent for Enhancing Communication Efficiency Using Large Language Models

no code implementations30 Jan 2024 Jiaxuan Li, Minxi Yang, Dahua Gao, Wenlong Xu, Guangming Shi

This paper proposes an image pragmatic communication framework based on a Pragmatic Agent for Communication Efficiency (PACE) using Large Language Models (LLM).

EVCap: Retrieval-Augmented Image Captioning with External Visual-Name Memory for Open-World Comprehension

no code implementations27 Nov 2023 Jiaxuan Li, Duc Minh Vo, Akihiro Sugimoto, Hideki Nakayama

Instead of relying on large amounts of data and/or scaling up network parameters, we introduce a highly effective retrieval-augmented image captioning method that prompts LLMs with object names retrieved from External Visual--name memory (EVCap).

Evaluating Large Language Models: A Comprehensive Survey

1 code implementation30 Oct 2023 Zishan Guo, Renren Jin, Chuang Liu, Yufei Huang, Dan Shi, Supryadi, Linhao Yu, Yan Liu, Jiaxuan Li, Bojian Xiong, Deyi Xiong

We hope that this comprehensive overview will stimulate further research interests in the evaluation of LLMs, with the ultimate goal of making evaluation serve as a cornerstone in guiding the responsible development of LLMs.

Partition-and-Debias: Agnostic Biases Mitigation via A Mixture of Biases-Specific Experts

1 code implementation ICCV 2023 Jiaxuan Li, Duc Minh Vo, Hideki Nakayama

However, most of these methods implicitly assume that a given image contains only one type of known or unknown bias, failing to consider the complexities of real-world biases.

Counterfactual reasoning: Testing language models' understanding of hypothetical scenarios

1 code implementation26 May 2023 Jiaxuan Li, Lang Yu, Allyson Ettinger

Current pre-trained language models have enabled remarkable improvements in downstream tasks, but it remains difficult to distinguish effects of statistical correlation from more systematic logical reasoning grounded on the understanding of real world.

A unified information-theoretic model of EEG signatures of human language processing

no code implementations16 Dec 2022 Jiaxuan Li, Richard Futrell

We advance an information-theoretic model of human language processing in the brain, in which incoming linguistic input is processed at two levels, in terms of a heuristic interpretation and in terms of error correction.

Counterfactual reasoning: Do language models need world knowledge for causal understanding?

1 code implementation6 Dec 2022 Jiaxuan Li, Lang Yu, Allyson Ettinger

Current pre-trained language models have enabled remarkable improvements in downstream tasks, but it remains difficult to distinguish effects of statistical correlation from more systematic logical reasoning grounded on understanding of the real world.

Anti-Asian Hate Speech Detection via Data Augmented Semantic Relation Inference

no code implementations14 Apr 2022 Jiaxuan Li, Yue Ning

We design a novel framework SRIC that simultaneously performs two tasks: (1) semantic relation inference between online posts and sentiment hashtags, and (2) sentiment classification on these posts.

Multi-scale Sparse Representation-Based Shadow Inpainting for Retinal OCT Images

no code implementations23 Feb 2022 Yaoqi Tang, Yufan Li, Hongshan Liu, Jiaxuan Li, Peiyao Jin, Yu Gan, Yuye Ling, Yikai Su

To address these challenges, we propose a novel multi-scale shadow inpainting framework for OCT images by synergically applying sparse representation and deep learning: sparse representation is used to extract features from a small amount of training images for further inpainting and to regularize the image after the multi-scale image fusion, while convolutional neural network (CNN) is employed to enhance the image quality.
