Extreme Values in Closed Networks
Predrag Jelenkovic, Petar Momcilovic
For a widely used hub-and-spoke closed product-form network consisting of an infinite-server node and several single-server queues, we characterize the maximum queue-length distrib…
Regularized Q-Learning with Linear Function Approximation
Jiachen Xi, Alfredo Garcia, Petar Momcilovic
Regularized Markov Decision Processes serve as models of sequential decision making under uncertainty wherein the decision maker has limited information processing capacity and/or…
A Probabilistic Approach to Growth Networks
Predrag Jelenkovic, Jane Kondev, Lishibanya Mohapatra +1
Widely used closed product-form networks have emerged recently as a primary model of stochastic growth of sub-cellular structures, e.g., cellular filaments. In the baseline model,…
Extended Vertical Lists for Temporal Pattern Mining from Multivariate Time Series
Anton Kocheturov, Petar Momcilovic, Azra Bihorac +1
Temporal Pattern Mining (TPM) is the problem of mining predictive complex temporal patterns from multivariate time series in a supervised setting. We develop a new method called th…
Comparing Clinical Judgment with MySurgeryRisk Algorithm for Preoperative Risk Assessment: A Pilot Study
Meghan Brennan, Sahil Puri, Tezcan Ozrazgat-Baslanti +6
Background: Major postoperative complications are associated with increased short and long-term mortality, increased healthcare cost, and adverse long-term consequences. The large…
Steady-state analysis of a multi-server queue in the Halfin-Whitt regime
David Gamarnik, Petar Momcilovic
We consider a multi-server queue in the Halfin-Whitt regime: as the number of servers grows without a bound, the utilization approaches 1 from below at the rate …
