The spread of behavior over social networks depends on the contact structure among individuals, and seeding the most influential agents can substantially enhance the extent of the spread. While the choice of the best seed set, known as influence...

District heating system is the major form of heat supply in many countries. However, the system lacks the motivation to utilize the thermal energy storage in the heat generation scheduling of combined heat and power plants, which leads to...

With the recent large-scale deployment of phasor measurement units (PMUs), power systems operators have noticed the persistent presence of low frequency forced oscillations. Due to their extraneous nature, locating the sources of these oscillations...

We consider the problem of high-dimensional error-in-variable regression where instead of directly observing the covariates, we observe its sparse, noisy version, a common thread of modern datasets. For this setup, we propose an algorithm that...

Memorization of data in deep neural networks has become a subject of significant research interest. We prove that overparameterized single layer fully connected autoencoders memorize training data: they produce outputs in (a non-linear version of)...

Information freshness and low latency communication is important to many emerging applications. Age of Information (AoI) serves as a metric of information freshness, and packet delay is a traditional metric of communication latency. We prove that...

Hybrid systems demonstrate both continuous and discrete behaviors, making it computationally difficult to verify and control. We introduce "polytopic trees”, which is a novel, efficient representation for reachability properties. The central idea is...

We consider infinite-dimensional convex quadratic optimization problems, with shift-invariant quadratic forms, subject to convex sample-wise constraints. From a systems perspective, the latter correspond to those of designing discrete-time systems...

Convex relaxations based upon semidefinite programming provide a powerful class of techniques for addressing challenging optimization problems across a broad spectrum of disciplines, including combinatorics, semialgebraic geometry, control theory,...

As data sets become larger, there is an increasing need to develop parallel algorithms. For this reason, there has been a new burst of interest in efficient data structures designed for asynchronous shared-memory multiprocessors. In this model, the...

Bayesian models are applied to probabilistic analysis of phenomena which deal with multiple external stochastic factors and unmeasurable variables. Considering the large amount of available data for the EV driving, recharging and grid services such...

Statistical learning theory has largely focused on learning and generalization given independent and identically distributed (i.i.d.) samples. Motivated by applications involving time-series data, there has been a growing literature on learning and...

Flexible resources such as batteries and demand-side management technologies are needed to handle future large shares of variable renewable power. Wind and solar power introduce more short-term uncertainty that have to be considered when making...
