Approximate Gradient Descent Convergence Dynamics for Adaptive Control on Heterogeneous Networks
Jean Carpentier, Sebastien Blandin
Adaptive control is a classical control method for complex cyber-physical systems, including transportation networks. In this work, we analyze the convergence properties of such me…
FASTER: Fusion AnalyticS for public Transport Event Response
Sebastien Blandin, Laura Wynter, Hasan Poonawala +2
Increasing urban concentration raises operational challenges that can benefit from integrated monitoring and decision support. Such complex systems need to leverage the full stack…
High-frequency crowd insights for public safety and congestion control
Karthik Nandakumar, Sebastien Blandin, Laura Wynter
We present results from several projects aimed at enabling the real-time understanding of crowds and their behaviour in the built environment. We make use of CCTV video cameras tha…
Robust commuter movement inference from connected mobile devices
Baoyang Song, Hasan Poonawala, Laura Wynter +1
The preponderance of connected devices provides unprecedented opportunities for fine-grained monitoring of the public infrastructure. However while classical models expect high qua…
A Probabilistic Model of the Bitcoin Blockchain
Marc Jourdan, Sebastien Blandin, Laura Wynter +1
The Bitcoin transaction graph is a public data structure organized as transactions between addresses, each associated with a logical entity. In this work, we introduce a complete p…
Characterizing Entities in the Bitcoin Blockchain
Marc Jourdan, Sebastien Blandin, Laura Wynter +1
Bitcoin has created a new exchange paradigm within which financial transactions can be trusted without an intermediary. This premise of a free decentralized transactional network h…
Stochastic on-time arrival problem in transit networks
Yang Liu, Sebastien Blandin, Samitha Samaranayake
This article considers the stochastic on-time arrival problem in transit networks where both the travel time and the waiting time for transit services are stochastic. A specific ch…
Robust Adaptive Routing Under Uncertainty
Arthur Flajolet, Sebastien Blandin, Patrick Jaillet
We consider the problem of finding an optimal history-dependent routing strategy on a directed graph weighted by stochastic arc costs when the objective is to minimize the risk of…
