Jumping Fluid Models and Delay Stability of Max-Weight Dynamics under Heavy-Tailed Traffic

no code implementations14 Nov 2021 Arsalan SharifNassab, John N. Tsitsiklis

We say that a random variable is $light$-$tailed$ if moments of order $2+\epsilon$ are finite for some $\epsilon>0$; otherwise, we say that it is $heavy$-$tailed$.

Blind identification of stochastic block models from dynamical observations

no code implementations22 May 2019 Michael T. Schaub, Santiago Segarra, John N. Tsitsiklis

We consider a blind identification problem in which we aim to recover a statistical model of a network without knowledge of the network's edges, but based solely on nodal observations of a certain process.

Private Sequential Learning

no code implementations6 May 2018 John N. Tsitsiklis, Kuang Xu, Zhi Xu

We formulate a private learning model to study an intrinsic tradeoff between privacy and query complexity in sequential learning.

Distributed Subgradient Methods and Quantization Effects

no code implementations8 Mar 2008 Angelia Nedić, Alex Olshevsky, Asuman Ozdaglar, John N. Tsitsiklis

We consider a convex unconstrained optimization problem that arises in a network of agents whose goal is to cooperatively optimize the sum of the individual agent objective functions through local computations and communications.
