Fully Probabilistic Design for Optimal Transport
Sarah Boufelja Y., Anthony Quinn, Martin Corless +1
The goal of this paper is to introduce a new theoretical framework for Optimal Transport (OT), using the terminology and techniques of Fully Probabilistic Design (FPD). Optimal Tra…
Closed-Loop View of the Regulation of AI: Equal Impact across Repeated Interactions
Quan Zhou, Ramen Ghosh, Robert Shorten +1
There has been much recent interest in the regulation of AI. We argue for a view based on civil-rights legislation, built on the notions of equal treatment and equal impact. In a c…
A smart electric bike for smart cities
Shaun Sweeney, Robert Shorten, David Timoney +2
This is a Masters Thesis completed at University College Dublin, Ireland in 2017 which involved augmenting an off-the-shelf electric bike with sensors to enable new services to be…
Improving Quality of Service for Users of DAG-based Distributed Ledgers
Andrew Cullen, Lianna Zhao, Luigi Vigneri +1
An outstanding problem in the design of distributed ledgers concerns policies that govern the manner in which users interact with the network. Network usability is crucial to the m…
Stochastic Model Predictive Control, Iterated Function Systems, and Stability
Vyacheslav Kungurtsev, Jakub Marecek, Robert Shorten
We present the observation that the process of stochastic model predictive control can be formulated in the framework of iterated function systems. The latter has a rich ergodic th…
Integral action for setpoint regulation control of a reaction-diffusion equation in the presence of a state delay
Hugo Lhachemi, Ammar Malik, Robert Shorten
This paper is concerned with the regulation control of a one-dimensional reaction-diffusion equation in the presence of a state-delay in the reaction term. The objective is to achi…
Secure Access Control for DAG-based Distributed Ledgers
Lianna Zhao, Luigi Vigneri, Andrew Cullen +3
Access control is a fundamental component of the design of distributed ledgers, influencing many aspects of their design, such as fairness, efficiency, traditional notions of netwo…
On node ranking in graphs
Ekaterina Dudkina, Michelangelo Bin, Jane Breen +9
The ranking of nodes in a network according to their ``importance'' is a classic problem that has attracted the interest of different scientific communities in the last decades. Th…
Markovian city-scale modelling and mitigation of micro-particles from tyres
Gunda Obereigner, Roman Overko, Serife Yilmaz +2
The recent uptake in popularity in vehicles with zero tailpipe emissions is a welcome development in the fight against traffic induced airborne pollutants. As vehicle fleets become…
Boundary Output Feedback Stabilization of State Delayed Reaction-Diffusion PDEs
Hugo Lhachemi, Robert Shorten
This paper studies the boundary output feedback stabilization of general 1-D reaction-diffusion PDEs in the presence of a state delay in the reaction term. The control input applie…
Reinforcement Learning with Algorithms from Probabilistic Structure Estimation
Jonathan P. Epperlein, Roman Overko, Sergiy Zhuk +4
Reinforcement learning (RL) algorithms aim to learn optimal decisions in unknown environments through experience of taking actions and observing the rewards gained. In some cases,…
Personalised Feedback Control, Social Contracts, and Compliance Strategies for Ensembles
Pietro Ferraro, Lianna Zhao, Christopher King +1
This paper describes the use of Distributed Ledger Technologies as a mean to enforce social contracts and to orchestrate the behaviour of agents in a smart city environment. Specif…
A Note on Order and Index Reduction for Descriptor Systems
Martin Corless, Robert Shorten
We present order reduction results for linear time invariant descriptor systems. Results are given for both forced and unforced systems as well methods for constructing the reduced…
On the derivation of stability properties for time-delay systems without constraint on the time-derivative of the initial condition
Hugo Lhachemi, Robert Shorten
Stability of retarded differential equations is closely related to the existence of Lyapunov-Krasovskii functionals. Even if a number of converse results have been reported regardi…
