Improvements in the approximations in current use can have enormous impact in many technological applications. I will discuss functional analysis, algorithmic development, and even optimal transport. But then I will focus on asymptotic analysis of density functionals, which is becoming increasingly important in the development of approximations. I will outline some formidable mathematical challenges, where any progress would be extremely useful.

TODAY: CompE Seminar Series: Azam Ikram: Root Cause Analysis of Failures in Microservices through Causal Discovery; BHEE 317 / Zoom, 12:00 Noon
by Satterfield, Mary Ann 08 Nov '22

Root Cause Analysis of Failures in Microservices through Causal Discovery Azam Ikram Advised by Prof. Saurabh Bagchi https://purdue-edu.zoom.us/j/93166268645?pwd=UlpSYWtqbTh3WFdHNEdQL29ELy9ldz… Meeting ID: 931 6626 8645 Passcode: 800947 Abstract: Most cloud applications use a large number of smaller sub-components (called microservices) that interact with each other in the form of a complex graph to provide the overall functionality to the user. While the modularity of the microservice architecture is beneficial for rapid software development, maintaining and debugging such a system quickly in cases of failure is challenging. We propose a scalable algorithm for rapidly detecting the root cause of failures in complex microservice architectures. The key ideas behind our novel hierarchical and localized learning approach are: (1) to treat the failure as an intervention on the root cause to quickly detect it, (2) only learn the portion of the causal graph related to the root cause, thus avoiding a large number of costly conditional independence tests, and (3) hierarchically explore the graph. The proposed technique is highly scalable and produces useful insights about the root cause, while the use of traditional techniques becomes infeasible due to high computation time. Our solution is application agnostic and relies only on the data collected for diagnosis. For the evaluation, we compare the proposed solution with a modified version of the PC algorithm and the state-of-the-art for root cause analysis. The results show a significant improvement in top-k recall while significantly reducing the execution time. Bio: I am a second-year Ph.D. student at ECE Purdue University working with Prof. Saurabh Bagchi. I'm broadly interested in large-scale distributed systems, cloud computing, computer networks, and applied machine learning in systems. My current research work focuses on providing fault diagnosability for cloud applications through causal inference. Another part of my work concentrates on making the serverless framework more applicable to the end user by reducing the latency and cost of serverless DAGs. Before joining Purdue, I was at LUMS where I worked with Prof. Zafar Ayyub Qazi to improve the latency of cellular control plane messages of 4G/LTE.

REMINDER - Seminar by Dr. Andy Lemmon of the University of Alabama, Tuesday, Nov. 1st
by Carte, Lori J 27 Oct '22

27 Oct '22

Tuesday, November 1, 2022, 11:00am WANG 1004 Enabling Next-Generation Power Electronics With Wide Band-Gap Semiconductors Dr. Andy Lemmon Associate Professor The University of Alabama During the last ten years, the maturity of wide band-gap (WBG) semiconductor technology has advanced rapidly. The most mature WBG semiconductor available today is the Silicon Carbide (SiC) MOSFET, which is now being deployed in commercial applications on a broad scale. SiC devices offer substantial performance advantages over traditional Silicon devices in terms of reduced losses, increased switching speed, and increased thermal capability. When this technology is properly implemented, these device-level performance advantages translate into converter-level and system-level benefits, such as increased efficiency and power density. For example, WBG converters have been demonstrated at ten times higher power density than legacy Silicon converters, without sacrificing conversion efficiency. In order to achieve such performance gains, SiC-based converters must be carefully optimized to take full advantage of the underlying semiconductor capabilities. Implementation of SiC-based converters using design principles developed for Silicon devices will yield sub-optimal performance. In some cases, this may produce converters that perform worse than legacy Silicon systems. Understanding the key design principles used to optimize converters for SiC devices is critical to attaining the performance entitlement of such systems. This talk will provide an overview of the concepts that must be understood to unlock the performance advantages of SiC semiconductors at the converter level. First, the characteristics of SiC devices will be explained, along with the procedures used to evaluate and quantify device-level performance. Second, guidance for implementing these devices in practical application circuits will be presented. Third, the metrology and instrumentation requirements for properly evaluating WBG converter implementations will be discussed. Fourth, future trends will be analyzed, including the challenges and opportunities associated with the implementation of medium-voltage (MV) SiC semiconductors. Case studies will be presented throughout this talk to demonstrate the concepts discussed, and to illustrate the presence of knowledge gaps that call for further investigation. Andrew N. Lemmon received the B.S. degree in electrical engineering from Christian Brothers University, Memphis, TN, USA, in 2000; the M.S. degree in electrical and computer engineering from The University of Memphis, Memphis, TN, USA, in 2009; and the Ph.D. degree in electrical engineering from Mississippi State University, Starkville, MS, USA, in 2013. >From 2000 to 2010, he was an Embedded Systems Design Engineer at FedEx Corporation in Memphis, TN, USA. From 2010 to 2013, he was a graduate research assistant in the Center for Advanced Vehicular Systems (CAVS) at Mississippi State University. He is currently an Associate Professor with the department of electrical and computer engineering at the University of Alabama, Tuscaloosa, AL, USA. His research interests include design and optimization of Silicon Carbide applications; development of compact behavioral models for power semiconductor devices; analysis, modeling, and design of power semiconductor packaging; and analysis, modeling, and mitigation of electromagnetic interference in power electronic systems. Dr. Lemmon is a Registered Professional Engineer and has been awarded four patents.
