Spatial clustering and common regulatory elements correlate with coordinated gene expression

no code implementations18 Jan 2019 Jingyu Zhang, HengYu Chen, Ruoyan Li, David A. Taft, Guang Yao, Fan Bai, Jianhua Xing

Many cellular responses to surrounding cues require temporally concerted transcriptional regulation of multiple genes.

Learning PAC-Bayes Priors for Probabilistic Neural Networks

no code implementations21 Sep 2021 Maria Perez-Ortiz, Omar Rivasplata, Benjamin Guedj, Matthew Gleeson, Jingyu Zhang, John Shawe-Taylor, Miroslaw Bober, Josef Kittler

We experiment on 6 datasets with different strategies and amounts of data to learn data-dependent PAC-Bayes priors, and we compare them in terms of their effect on test performance of the learnt predictors and tightness of their risk certificate.

Meta-Learning Regrasping Strategies for Physical-Agnostic Objects

no code implementations23 May 2022 Ning Gao, Jingyu Zhang, Ruijie Chen, Ngo Anh Vien, Hanna Ziesche, Gerhard Neumann

Grasping inhomogeneous objects in real-world applications remains a challenging task due to the unknown physical properties such as mass distribution and coefficient of friction.

On the Blind Spots of Model-Based Evaluation Metrics for Text Generation

1 code implementation20 Dec 2022 Tianxing He, Jingyu Zhang, Tianle Wang, Sachin Kumar, Kyunghyun Cho, James Glass, Yulia Tsvetkov

In this work, we explore a useful but often neglected methodology for robustness analysis of text generation evaluation metrics: stress tests with synthetic data.

Spatio-Temporal Domain Awareness for Multi-Agent Collaborative Perception

no code implementations ICCV 2023 Kun Yang, Dingkang Yang, Jingyu Zhang, Mingcheng Li, Yang Liu, Jing Liu, Hanqi Wang, Peng Sun, Liang Song

In this paper, we propose SCOPE, a novel collaborative perception framework that aggregates the spatio-temporal awareness characteristics across on-road agents in an end-to-end manner.

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.

The Language Barrier: Dissecting Safety Challenges of LLMs in Multilingual Contexts

no code implementations23 Jan 2024 Lingfeng Shen, Weiting Tan, Sihao Chen, Yunmo Chen, Jingyu Zhang, Haoran Xu, Boyuan Zheng, Philipp Koehn, Daniel Khashabi

As the influence of large language models (LLMs) spans across global communities, their safety challenges in multilingual settings become paramount for alignment research.

k-SemStamp: A Clustering-Based Semantic Watermark for Detection of Machine-Generated Text

no code implementations17 Feb 2024 Abe Bohan Hou, Jingyu Zhang, Yichen Wang, Daniel Khashabi, Tianxing He

Recent watermarked generation algorithms inject detectable signatures during language generation to facilitate post-hoc detection.

Changes in Tweet Geolocation over Time: A Study with Carmen 2.0

1 code implementation COLING (WNUT) 2022 Jingyu Zhang, Alexandra DeLucia, Mark Dredze

Despite the importance of these tools for data curation, the impact of tweet language, country of origin, and creation date on tool performance remains largely unknown.

Study of Manifestation of Civil Unrest on Twitter

1 code implementation WNUT (ACL) 2021 Abhinav Chinta, Jingyu Zhang, Alexandra DeLucia, Mark Dredze, Anna L. Buczak

Twitter is commonly used for civil unrest detection and forecasting tasks, but there is a lack of work in evaluating how civil unrest manifests on Twitter across countries and events.
