Monday, November 27, 2017Agostino Capponi  BailIns And BailOuts: Incentives, Connectivity, And Systemic StabilitySeminar  November 27  3:305 p.m.  3108 Etcheverry Hall Agostino Capponi, Columbia University Industrial Engineering & Operations Research We develop a framework to analyze the consequences of alternative designs for interbank networks, in which a failure of one bank may lead to others. Earlier work had suggested that, provided shocks were not too large (or too correlated), denser networks were preferred to more sparsely connected networks because they were better able to absorb shocks. With large shocks, especially when systems are... More > Jon Lee — Comparing relaxations via volume for nonconvex optimizationColloquium  November 27  3:305 p.m.  3108 Etcheverry Hall Jon Lee, University of Michigan Industrial Engineering & Operations Research Abstract: Practical exact methods for global optimization of mixedinteger nonlinear optimization formulations rely on convex relaxation. Then, one way or another (via refinement and/or disjunction), global optimality is sought. Success of this paradigm depends on balancing tightness and lightness of relaxations. We will investigate this from a mathematical viewpoint, comparing polyhedral...

So an interesting question is how to allocate the limited resources to maximize our welfare. Monday, February 12, 2018Georgina Hall  LP, SOCP, and optimizationfree approaches to sum of squares optimizationSeminar: Distinguished Lecture Series  February 12  3:305 p.m.  3108 Etcheverry Hall Georgina Hall, Princeton University Industrial Engineering & Operations Research The problem of optimizing over the cone of nonnegative polynomials is a fundamental problem in computational mathematics, with applications to polynomial optimization, control, machine learning, game theory, and combinatorics, among others. Wednesday, February 14, 2018Eric Friedlander  MeanField Methods In Large Stochastic NetworksSeminar  February 14  3:305 p.m.  540 Cory Hall Eric Friedlander, University of North Carolina  Chapel Hill Industrial Engineering & Operations Research Abstract: Analysis of largescale communication networks (e.g. ad hoc wireless networks, cloud computing systems, server networks etc.) is of great practical interest. The massive size of such networks frequently makes direct analysis intractable. Asymptotic approximations using hydrodynamic and diffusion scaling limits provide useful methods for approaching such problems. In this talk, we study... More > Friday, February 16, 2018Zeyu Zheng  TopDown Statistical ModelingSeminar  February 16  23:30 p.m.  3108 Etcheverry Hall Zeyu Zheng, Stanford University Industrial Engineering & Operations Research Abstract: In this talk, we will argue that datadriven service systems engineering should take a statistical perspective that is guided by the decisions and performance measures that are critical from a managerial perspective. We further take the view that the statistical models will often be used as inputs to simulations that will be used to drive either capacity decisions or realtime decisions... More > Wednesday, February 21, 2018Weina Wang Delay Bounds And Asymptotics In Cloud Computing SystemsSeminar: Distinguished Lecture Series  February 21  3:305 p.m.  3110 Etcheverry Hall Weina Wang, Illinois UrbanaCampaign Industrial Engineering & Operations Research With the emergence of bigdata technologies, cloud computing systems are growing rapidly in size and becoming more and more complex, making it costly to conduct experiments and simulations. Therefore, modeling computing systems and characterizing their performance analytically are more critical than ever in identifying bottlenecks, informing system design, and facilitating provisioning. Monday, February 26, 2018Barna Saha  Efficient FineGrained AlgorithmsSeminar  February 26  3:305 p.m.  3108 Etcheverry Hall Barna Saha, University of Massachusetts Amherst Industrial Engineering & Operations Research Abstract: One of the greatest successes of computational complexity theory is the classification of countless fundamental computational problems into polynomialtime and NPhard ones, two classes that are often referred to as tractable and intractable, respectively. However, this crude distinction of algorithmic efficiency is clearly insufficient when handling today's large scale of data. We need...

More > Tuesday, July 31, 2018Seminar 217, Risk Management: A Term Structure Model for Dividends and Interest RatesSeminar  July 31  23:30 p.m.  1011 Evans Hall Speaker: Damir Filipović, Ecole Polytechnique Fédérale de Lausanne Consortium for Data Analytics in Risk Over the last decade, dividends have become a standalone asset class instead of a mere side product of an equity investment. We introduce a framework based on polynomial jumpdiffusions to jointly price the term structures of dividends and interest rates. Prices for dividend futures, bonds, and the dividend paying stock are given in closed form. Tuesday, August 28, 2018Seminar 217, Risk Management: Is motor insurance ratemaking going to change with telematics and semiautonomous vehicles?Seminar  August 28  11 a.m.12:30 p.m.  1011 Evans Hall Speaker: Montserrat Guillen, University of Barcelona Consortium for Data Analytics in Risk Many automobile insurance companies offer the possibility to monitor driving habits and distance driven by means of telematics devices installed in the vehicles. This provides a novel source of data that can be analysed to calculate personalised tariffs. For instance, drivers who accumulate a lot of miles should be charged more for their insurance coverage than those who make little use of their...
