Location-Based Service (LBS) Data Quality Metrics and Effects on Mobility Inference

Autor: Wu, Xinhua, Wang, Yanchao, Ugurel, Ekin, Chen, Cynthia, Huang, Shuai, Wang, Qi R.

Today, GPS-equipped mobile devices are ubiquitous, and they generate Location-Based Service (LBS) data, which has become a critical resource for understanding human mobility. However, inherent limitations in LBS datasets, primarily characterized by d

Event detection from novel data sources: Leveraging satellite imagery alongside GPS traces

Autor: Ugurel, Ekin, Coenen, Steffen, Chen, Minda Zhou, Chen, Cynthia

Rapid identification and response to breaking events, particularly those that pose a threat to human life such as natural disasters or conflicts, is of paramount importance. The prevalence of mobile devices and the ubiquity of network connectivity ha

AttentionViz: A Global View of Transformer Attention

Autor: Yeh, Catherine, Chen, Yida, Wu, Aoyu, Chen, Cynthia, Viégas, Fernanda, Wattenberg, Martin

Transformer models are revolutionizing machine learning, but their inner workings remain mysterious. In this work, we present a new visualization technique designed to help researchers understand the self-attention mechanism in transformers that allo

Recursive Methods for Synthesizing Permutations on Limited-Connectivity Quantum Computers

Autor: Chen, Cynthia, Schmitt, Bruno, Zhang, Helena, Bishop, Lev S., Javadi-Abhari, Ali

Publikováno v: DAC 22: Proceedings of the 59th ACM IEEE Design Automation Conference, July 2022, Pages 7-12

We describe a family of recursive methods for the synthesis of qubit permutations on quantum computers with limited qubit connectivity. Two objectives are of importance: circuit size and depth. In each case we combine a scalable heuristic with a non-

Mobility Analysis Workflow (MAW): An accessible, interoperable, and reproducible container system for processing raw mobile data

Autor: Guan, Xiangyang, Chen, Cynthia, Ren, Ian, Yeung, Ka Yee, Hung, Ling-Hong, Lloyd, Wes J.

Mobility analysis, or understanding and modeling of people's mobility patterns in terms of when, where, and how people move from one place to another, is fundamentally important as such information is the basis for large-scale investment decisions on
