Generalization of Standard Matrix Completion

Joydeep Ghosh and student Suriya Gunasekar work on the generalization of standard matrix completion in various aspects. In previous work, we have proposed tractable estimators for matrix completion with observations arising from heterogeneous datatypes and heterogeneous noise models. In a more recent work, we focus on consistency results for the collective matrix completion problem of jointly recovering a collection of matrices with shared structure.

Bayesian Sparse Principal Component Analysis

Several real-life high dimension datasets can be reasonably represented as a
linear combination of a few sparse vectors. Succinct representation of such data with a few selected variables is highly desirable for such cases. A Bayesian setup is useful because the limitation of knowing a limited number of high dimensional data points can be alleviated by well-designed domain-specific priors.

What multislope path loss models tell us about the fundamental limits of wireless network densification in 5G and beyond

A vast majority of the increased mobile data throughput has been enabled by ever-increasing densification, i.e. adding more base stations and access points that have a wired backhaul connection.  This trend is set to continue for the next decade at least, primarily through the provisioning of small cells such as pico and femtocells.  What if we reached a point where adding more infrastructure did not allow increased wireless network throughput?  This would be comparable to the impending end of "Moore's Law"; a cataclysmic event having far-reaching consequences.

Networks-of-Systems Simulation

In future computing systems, such as the Internet-of-Things (IoT), functionality is increasingly defined by the networked connectivity of spatially distributed devices. This, however, poses fundamentally new design challenges and tradeoffs. Computation and communication need to be tightly coupled and jointly explored, e.g. to determine whether a functionality should be performed locally or remotely over the network in order to achieve the best performance and energy consumption.

WNCG Faculty and Students Showcase Innovation During SXSW 2015

An incubator of cutting-edge technologies and digital creativity, SXSW Interactive 2015 featured five days of presentations and panels from the brightest minds in emerging technology. Special programs showcased new websites, video games and startup ideas from the community.

WNCG at SXSW Interactive 2015

WNCG Faculty and students met on Sunday with researchers from the Center for Transportation Research (CTR) and other UT Austin Cockrell School Engineers during the first-ever UT Village at SXSW Interactive 2015. 

This year's event featured panels and interactive research demonstrations and was open to all SXSW Interactive 2015 Badge Holders. Click the image below to view the complete slideshow from the day's events.


Inaugural D-STOP Symposium Explores Pathways to Connected, Autonomous Transportation World

In 2013, 32,719 fatalities resulted from traffic crashes, most of which were caused by driver error. Across the globe, people are facing longer commutes and five Texas communities are in the top 26 most congested cities in the United States. Traffic congestion creates about 4.8 billion hours of travel delay and affects the environment through increased carbon footprints and higher fuel consumption.

Student Ahmed Alkhateeb Presents Invited Talk at ITA 2015 Graduation Day

WNCG PhD Student, Ahmed Alkhateeb, recently presented an invited talk during the Graduation Day at the Information Theory and Applications (ITA) Workshop 2015.

Graduation Day features outstanding graduate students and postdoctoral researchers seeking academic positions and provides them with an opportunity to present their work to a broad audience of researchers and faculty. They are the only ITA talks presented by students, and several past Graduation Day presenters have subsequently joined academic institutions.

WNCG Welcomes New Director for Three-Year Term

Every few years, WNCG welcomes a new Director and Associate Director from among its faculty ranks. With an academic culture that encourages openness and research collaborations among equals, the rotation of Directors provides each faculty member with the opportunity to lead WNCG.
