RASP: A Drone-based Reconfigurable Actuation and Sensing Platform Towards Ambient Intelligent Systems

no code implementations19 Mar 2024 Minghui Zhao, Junxi Xia, Kaiyuan Hou, Yanchen Liu, Stephen Xia, Xiaofan Jiang

Realizing consumer-grade drones that are as useful as robot vacuums throughout our homes or personal smartphones in our daily lives requires drones to sense, actuate, and respond to general scenarios that may arise.

SISSA: Real-time Monitoring of Hardware Functional Safety and Cybersecurity with In-vehicle SOME/IP Ethernet Traffic

1 code implementation21 Feb 2024 Qi Liu, Xingyu Li, Ke Sun, Yufeng Li, Yanchen Liu

Scalable service-Oriented Middleware over IP (SOME/IP) is an Ethernet communication standard protocol in the Automotive Open System Architecture (AUTOSAR), promoting ECU-to-ECU communication over the IP stack.

Decoding Susceptibility: Modeling Misbelief to Misinformation Through a Computational Approach

no code implementations16 Nov 2023 Yanchen Liu, Mingyu Derek Ma, Wenna Qin, Azure Zhou, Jiaao Chen, Weiyan Shi, Wei Wang, Diyi Yang

Using COVID-19 as a testbed domain, our experiments demonstrate a significant alignment between the susceptibility scores estimated by our computational modeling and human judgments, confirming the effectiveness of this latent modeling approach.

Misinformation

Task-Agnostic Low-Rank Adapters for Unseen English Dialects

1 code implementation2 Nov 2023 Zedian Xiao, William Held, Yanchen Liu, Diyi Yang

Large Language Models (LLMs) are trained on corpora disproportionally weighted in favor of Standard American English.

MIDDAG: Where Does Our News Go? Investigating Information Diffusion via Community-Level Information Pathways

no code implementations4 Oct 2023 Mingyu Derek Ma, Alexander K. Taylor, Nuan Wen, Yanchen Liu, Po-Nien Kung, Wenna Qin, Shicheng Wen, Azure Zhou, Diyi Yang, Xuezhe Ma, Nanyun Peng, Wei Wang

We present MIDDAG, an intuitive, interactive system that visualizes the information propagation paths on social media triggered by COVID-19-related news articles accompanied by comprehensive insights, including user/community susceptibility level, as well as events and popular opinions raised by the crowd while propagating the information.

Textureless Deformable Surface Reconstruction with Invisible Markers

no code implementations25 Aug 2023 Xinyuan Li, Yu Ji, Yanchen Liu, Xiaochen Hu, Jinwei Ye, Changxi Zheng

Leveraging the markers, we design a multi-camera system that captures surface deformation under the UV light and the visible light in a time multiplexing fashion.

DADA: Dialect Adaptation via Dynamic Aggregation of Linguistic Rules

1 code implementation22 May 2023 Yanchen Liu, William Held, Diyi Yang

We show that DADA is effective for both single task and instruction finetuned language models, offering an extensible and interpretable framework for adapting existing LLMs to different English dialects.

Dialect Identification

SMoA: Sparse Mixture of Adapters to Mitigate Multiple Dataset Biases

no code implementations28 Feb 2023 Yanchen Liu, Jing Yan, Yan Chen, Jing Liu, Hua Wu

Recent studies reveal that various biases exist in different NLP tasks, and over-reliance on biases results in models' poor generalization ability and low adversarial robustness.

Cardiac Adipose Tissue Segmentation via Image-Level Annotations

no code implementations9 Jun 2022 Ziyi Huang, Yu Gan, Theresa Lye, Yanchen Liu, Haofeng Zhang, Andrew Laine, Elsa Angelini, Christine Hendon

To lessen the need for pixel-wise labeling, we develop a two-stage deep learning framework for cardiac adipose tissue segmentation using image-level annotations on OCT images of human cardiac substrates.

Semantic-Oriented Unlabeled Priming for Large-Scale Language Models

no code implementations12 Feb 2022 Yanchen Liu, Timo Schick, Hinrich Schütze

Due to the high costs associated with finetuning large language models, various recent works propose to adapt them to specific tasks without any parameter updates through in-context learning.

Automatic Symmetry Discovery with Lie Algebra Convolutional Network

1 code implementation NeurIPS 2021 Nima Dehmamy, Robin Walters, Yanchen Liu, Dashun Wang, Rose Yu

Existing equivariant neural networks require prior knowledge of the symmetry group and discretization for continuous groups.

Lie Algebra Convolutional Neural Networks with Automatic Symmetry Extraction

no code implementations1 Jan 2021 Nima Dehmamy, Yanchen Liu, Robin Walters, Rose Yu

We propose to learn the symmetries during the training of the group equivariant architectures.

Approximate Network Symmetry

no code implementations9 Dec 2020 Yanchen Liu

We define a new measure of network symmetry that is capable of capturing approximate global symmetries of networks.
