Prophet Inequality with Correlated Arrival Probabilities, with Application to Two Sided Matchings

The classical Prophet Inequality arises from a fundamental problem in optimal-stopping theory. In this problem, a gambler sees a finite sequence of independent, non-negative random variables. In this paper, we prove a corresponding bound for correlated non-negative random variables. We apply this new prophet inequality to the design of algorithms for a class of two-sided bipartite matching problems that underlie online task assignment problems.

Google in Chapel Hill: Entangled With Graphics

Duke Computer Science Colloquium
Speaker Name
Mike Reed
Location
The talk will be virtual on Zoom.
Date and Time
-

For 15+ years, Google has had an engineering office in Chapel Hill. Come hear how that came to be, and what the teams are working on. Learn about the graphic engine in Android and Chrome, and how that technology has changed/evolved over time. Get a sampling of current efforts and challenges, and how some of that work inspired a class at UNC.

Building a New Generation of Data Center Network on Top of Programmable Data Planes

Systems and Networking Seminar
Speaker Name
Hongqiang Liu
Location
The talk will be virtual on Zoom.
Date and Time
-

Based on our two recent publications, HPCC (SIGCOMM'19) and NetSeet (SIGCOMM'20), this talk will introduce the performance and reliability challenges faced by state-of-the-art data center networks in practice.

We will look at a vision of how the programmability in the data plane can potentially address these challenges, and the efforts Alibaba Cloud is making towards this direction.

Who's Calling? Characterizing Robocalls through Audio and Metadata Analysis

Duke Privacy and Security Seminar
Speaker Name

Location
The talk will be virtual on Zoom.
Date and Time

Unsolicited calls are one of the most prominent security issues facing individuals today. Despite wide-spread anecdotal discussion of the problem, many important questions remain unanswered. In this paper, we present the first large-scale, longitudinal analysis of unsolicited calls to a honeypot of up to 66,606 lines over 11 months. From call metadata we characterize the long-term trends of unsolicited calls, develop the first techniques to measure voicemail spam, wangiri attacks, and identify unexplained high-volume call incidences.

GamesCrafters: Solving the World’s Board Games with Computational Game Theory

Miscellaneous Talk
Speaker Name
Dan Garcia
Location
The talk will be virtual on Zoom.
Date and Time
-
The talk, which is for computer science students and anyone else interested in Computational Game Theory, will begin with the foundational principles of abstract strategy games, explain how we exhaustively solve the games (with a delightful small game participants play with their neighbors called “10-to-0-by-1-or-2”), and conclude with a demonstration of the GAMESMAN system we’ve collectively built over the span of almost 20 years.

High Performance Graph Mining System and Architecture

Duke Electrical Computer Engineering Colloquium
Speaker Name
Xuehai Qian
Location
The talk will be virtual on Zoom.
Date and Time
-

Graph mining, which finds all embeddings matching specific patterns, is a fundamental task in many applications. In this talk, I will present the first graph mining system that decomposes the target pattern into several subpatterns, and then computes the count of each.
