POSTPONED: Applying Machine Learning in Online Revenue Management

Speaker: David Simchi-Levi (MIT)

THIS TALK HAS BEEN POSTPONED DUE TO THE SNOW EMERGENCY. THE NEW DATE WILL BE IN FALL 2015.   *********************************** In a dynamic pricing problem where the demand function is unknown a priori, price experimentation can be used...

Quantifying Cascading Failure Propagation in Blackouts of Electrical Transmission Networks

Speaker: Ian Dobson (Iowa State)

Large blackouts involve complicated series of tens or hundreds of events, but usually involve the cascading outage of transmission lines. Small cascades of line outages occur routinely, but usually do not lead to load shed because the power...

LIDS-SSRC Seminar: Endogenous Stratification in Randomized Experiments

Speaker: Alberto Abadie (Harvard University)

Researchers and policy makers are often interested in estimating how policy interventions affect the outcomes of those individuals most in need of help. For example, a researcher may be interested in estimating the effect of financial aid on...

New Approaches to Power System Security and Stability Assessment

Speaker: Kostya Turitsyn (MIT)

Dynamic Security Assessment is one of the most challenging computational problems in power systems. Large size of power systems and immense variety of possible contingency scenarios make the brute-force simulation approaches overly...

Mapping, Localization, and Self-Driving Vehicles

Speaker: John Leonard (MIT)

This talk will discuss the critical role of mapping and localization in the development of self-driving vehicles. After a discussion of some of the recent amazing progress and open technical challenges in the development of self-driving...

Competition with Shared Wireless Spectrum

Speaker: Randall Berry (Northwestern University)

The demand for wireless data is projected to continue to rapidly grow. Meeting this demand will require that wireless data services have access to additional RF spectrum. It is widely recognized that this in turn will require new approaches...

LIDS-SSRC Seminar: On the Consequences of Information in the First-Price Auction

Speaker: Dirk Bergemann (Yale University)

This presentation will discuss how the structure of information can affect welfare outcomes in the first-price auction. For a given distribution of buyers' valuations, we characterize all Bayesian equilibria that can arise under any...

Optimal Trajectory Planning and Assignment Problems for Kinematic Agents with State-Dependent Metrics

Speaker: Panagiotis Tsiotras (Georgia Tech)

In the recent years there has been an increased interest in developing control and navigation strategies for multi-agent systems. Typical tasks include guiding a team of small autonomous agents (e.g., UAVs, UUVs) towards a given goal, or...

LIDS-SSRC Seminar: Systemic Risk and Network Formation

Speaker: Rakesh Vohra (Univ. of Pennsylvania)

This seminar will introduce a model of endogenous network formation and systemic risk in which strategic agents form networks that efficiently trade off the possibility of systemic risk with the benefits of trade. Efficiency is a consequence...

Fundamental Limits of Community Detection in Stochastic Block Models

Speaker: Emmanuel Abbe (Princeton)

Abstract: With the abundance of networks and data sets organized as similarity graphs, community detection is a fast growing field. Yet the methodologies are still mainly driven by heuristics. This talk focuses on a popular network model...

LIDS-SSRC Seminar: Big Data, Big Brother, and Systemic Risk Management in the Financial System

Speaker: Andrew Lo (MIT)

A recurring theme among the many narratives of the financial crisis of 2008 is the complexity of the financial system and the failure of private- and public-sector policies to anticipate and attenuate the crisis. This failure may be a...

Computation and Incentives in Social Computing

Speaker: Yiling Chen (Harvard University)

Social computing is a broad and evolving research area that concerns harnessing human intelligence to solve computational problems. The success of a social computing system relies on complex and dynamic interactions among people and...
