December 2018

Naomi E. Leonard

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

Naomi E. Leonard (Princeton University)

32-155

Title Talk: Symmetry, Bifurcation, and Multi-Agent Decision-Making Speaker: Naomi E. Leonard Affiliation: Princeton University Abstract: Prof. Leonard will present nonlinear dynamics for distributed decision-making that derive from principles of symmetry and bifurcation. Inspired by studies of animal groups, including house-hunting honeybees and schooling fish, the nonlinear dynamics describe a group of interacting agents that can manage flexibility as well as stability in response to a changing environment. Bio: Prof. Naomi Ehrich Leonard is Edwin S. Wilsey Professor of Mechanical and…

Benjamin Hobbs

November 19, 2018 @ 4:00 pm - 5:00 pm

Benjamin Hobbs (Johns Hopkins University)

32-155

Title Talk: Modeling Electricity Markets with Complementarity: Why It's Important (and Fun) Speaker: Benjamin Hobbs Affiliation: Johns Hopkins University Abstract: Electric power: done wrong, it drags the economy and environment down; done right, it could help to create a more efficient, brighter, and cleaner future. Better policy, planning, and operations models--both simple analytical, and complex computational ones--are essential if we're going to do it right. Better modeling is also fun, as the math of electricity models is inherently interesting and revealing…

Christos Papadimitriou

October 29, 2018 @ 4:00 pm - 5:00 pm

Christos Papadimitriou (Columbia University)

32-155

Title Talk: Computing with Assemblies Speaker: Christos Papadimitriou Affiliation: Columbia University Abstract: Computation in the brain has been modeled productively at many scales, ranging from molecules to dendrites, neurons, and synapses, all the way to the whole brain models useful in cognitive science. I will discuss recent work on an intermediate layer, involving assemblies of neurons --- that is to say, sets of neurons firing together in a repetitive pattern whenever we think of a particular memory, concept or idea.…

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…
