Robust Reward Placement under Uncertainty
Petros Petsinis, Kaichen Zhang, Andreas Pavlogiannis +2
We consider a problem of placing generators of rewards to be collected by randomly moving agents in a network. In many settings, the precise mobility pattern may be one of several…
Seed Selection in the Heterogeneous Moran Process
Petros Petsinis, Andreas Pavlogiannis, Josef Tkadlec +1
The Moran process is a classic stochastic process that models the rise and takeover of novel traits in network-structured populations. In biological terms, a set of mutants, each w…
Maximizing the Probability of Fixation in the Positional Voter Model
Petros Petsinis, Andreas Pavlogiannis, Panagiotis Karras
The Voter model is a well-studied stochastic process that models the invasion of a novel trait (e.g., a new opinion, social meme, genetic mutation, magnetic spin) in a network…
Analysis of key flavors of event-driven predictive maintenance using logs of phenomena described by Weibull distributions
Petros Petsinis, Athanasios Naskos, Anastasios Gounaris
This work explores two approaches to event-driven predictive maintenance in Industry 4.0 that cast the problem at hand as a classification or a regression one, respectively, using…
