Speaker: Eva Agapaki (University of Cambridge)
The cost of modelling existing industrial facilities is currently considered to counteract the benefits of the models in maintaining and retrofitting a facility. 90% of the modelling cost is typically spent on labour for converting point...
September 26, 2018 to September 27, 2018
Speaker: Devendra Shelar (MIT Civil and Environmental Engineering)
We propose a new approach for utilizing distributed energy resources (DERs) and microgrids for improving the resilience of electricity distribution networks to correlated cyber-physical failures. Such failures can result from random faults (...
October 3, 2018 to October 4, 2018
Speaker: Jingzhao Zhang (LIDS)
We study gradient-based optimization methods obtained by directly discretizing a second-order ordinary differential equation (ODE) related to the continuous limit of Nesterov's accelerated gradient method. When the function is smooth enough...
October 10, 2018 to October 11, 2018
Speaker: Mathieu Dahan (MIT Center for Computational Engineering)
We study an abstract problem regarding probability distributions on posets. The problem is to resolve the existence of a probability distribution over subsets of a poset, such that a set of constraints involving marginal probabilities of the...
October 17, 2018 to October 18, 2018
Speaker: Dongchan Lee (Mechanical Engineering)
Convex restriction identifies the convex subset of a general nonconvex feasible set described by nonlinear equality and inequality constraints. Nonlinear optimization problems often rely on convex relaxations, which can be interpreted as...
October 24, 2018 to October 25, 2018
Speaker: Xinbo Geng (Texas A&M University)
Motivated by the uncertainties from deepening penetration of renewable energy resources in power systems, we study the day-ahead scheduling problem in electricity markets. We formulate the chance-constrained unit commitment problem...
October 31, 2018 to November 1, 2018
Speaker: Jinglong Zhao (IDSS)
Our work is based on the classical dynamic pricing problem. From our collaborations with a large Consumer Packaged Goods company, we have found that while they appreciate the advantages of dynamic pricing, it is operationally beneficial for...
November 7, 2018 to November 8, 2018
Speaker: Tong Huang (Texas A&M University)
This talk concerns about developing physically interpretable algorithms for large dynamical systems such as the power grid. The problem of source localization is formulated as one of identifying the sparse component in robust principal...
November 14, 2018 to November 15, 2018
Speaker: Yuhao Wang (LIDS & EECS)
We consider the problem of estimating high-dimensional precision matrices for multivariate totally positive of order two (MTP2) distributions. Such distribution is of interest in financial econometrics, where the distribution of stock price...
November 20, 2018 to November 21, 2018
Speaker: Julia Gaudio (LIDS & ORC)
We introduce the Attracting Random Walks model, which is an attractive interacting particle system. In the model, particles move between adjacent vertices of a graph G, with transition probabilities that depend positively on particle counts...
November 28, 2018 to November 29, 2018
Speaker: Martín Zubeldía (LIDS)
We consider a large distributed service system with N servers that have random service rates, where there is a stream of incoming jobs that consist of K<<N identical tasks that can be executed in parallel. We assume that the K tasks...
December 5, 2018 to December 6, 2018
Speaker: Tuhin Sarkar (LIDS & IDSS)
We address two fundamental problems in the context of jump linear systems (JLS). The first problem is concerned with characterizing the minimal state space dimension solely from input-output pairs and without any knowledge of the number of...
December 12, 2018 to December 13, 2018
Speaker: Bolun Xu (MIT Energy Initiative)
The stochastic future can be reduced to a cost-to-go value function of the system state variable for fast and optimal real-time decision making, following the concept of dynamic programming, this serves as a potential solution to the ongoing...
