Augmented Lagrangians and Decomposition in Convex and Nonconvex Programming

October 15, 2018 @ 4:00 pm - 5:00 pm

Terry Rockafellar (University of Washington)

32-155

LIDS Seminar Series Speaker: Terry Rockafellar Affiliation: University of Washington Abstract: Multiplier methods based on augmented Lagrangians are attractive in convex and nonconvex programming for their stabilizing and even convexifying properties. They have widely been seen, however, as incompatible with taking advantage of a block-separable structure. In fact, when articulated in the right way, they can produce decomposition algorithms in which low-dimensional subproblems can be solved in parallel. Convergence in the nonconvex case is, of course, just local, but is…

LIDS Seminar Series – Regret of Queueing Bandits

September 17, 2018 @ 4:00 pm - 5:00 pm

Sanjay Shakkotai (University of Texas, Austin)

32-155

LIDS Seminar Series Speaker: Sanjay Shakkotai Affiliation: University of Texas, Austin Abstract: We consider a variant of the multiarmed bandit (MAB) problem where jobs or tasks queue for service, and service rates of different servers (agents) may be unknown. Such (queueing+learning) problems are motivated by a vast range of service systems, including supply and demand in online platforms (e.g., Uber, Lyft, Airbnb, Upwork, etc.), order flow in financial markets (e.g., limit order books), communication systems, and supply chains. We study…

LIDS Seminar Series – Streaming Analytics for the Smart Grid

September 10, 2018 @ 4:00 pm - 5:00 pm

Le Xie (Texas A&M University)

32-155

LIDS Seminar Series Speaker: Le Xie Affiliation: Texas A&M University   Abstract: How to conduct real-time analytics of streaming measurement data in the power grid? This talk offers a dynamic systems approach to utilizing data of different time scale for improved monitoring of the grid cyber and physical security. The first example of the talk presents how to leverage synchrophasor data dimensionality reduction and Robust Principal Component Analysis for early anomaly detection, visualization, and localization. The second example presents an…

A Rationally Designed Biomolecular Integral Feedback Control System for Robust Gene Regulation

May 8, 2018 @ 3:00 pm - 4:00 pm

Mustafa Khammash ( ETH Zurich )

32-141

Abstract Humans have been influencing the DNA of plants and animals for thousands of years through selective breeding. Yet it is only over the last 3 decades or so that we have gained the ability to manipulate the DNA itself and directly alter its sequences through the modern tools of genetic engineering. This has revolutionized biotechnology and ushered in the era of synthetic biology. Among the possible applications enabled by synthetic biology is the design and engineering of feedback control…

Community-based and Peer-to-peer Electricity Markets

April 18, 2018 @ 2:00 pm - 3:00 pm

Pierre Pinson ( Technical University of Denmark )

MIT Building E18, Room 304

Abstract The deployment of distributed renewable generation capacities, new ICT capabilities, as well as a more proactive role of consumers, are all motivating rethinking electricity markets in a more distributed and consumer-centric fashion. After motivating the design of various forms of consumer-centric electricity markets, we will focus on two alternative constructs (which could actually be unified) consisting in community-based and peer-to-peer electricity markets. The mathematical framework for these markets will be described, with focus on negotiation and clearing algorithms in…

Finding Online Extremists in Social Networks

April 10, 2018 @ 3:00 pm - 4:00 pm

Tauhid Zaman (MIT)

32-141

Abstract Online extremists in social networks pose a new form of threat to the general public. These extremists range from cyber bullies who harass innocent users to terrorist organizations such as ISIS that use social networks to spread propaganda. Currently, social networks suspend the accounts of such extremists in response to user complaints, but these extremist users simply create new accounts and continue their activities. In this talk, we present a new set of operational capabilities to help authorities mitigate…
