(Institute of Electrical and Electronics Engineers (IEEE), 2013-06)With changes in life expectancy across the world, technologies enhancing well-being of individuals, specifically for older people, are subject to a new stream of research and development. In this paper we present the ... -
Action and perception for spatiotemporal patterns
Biehl, Martin; Polani, Daniel (MIT Press, 2017-09)This is a contribution to the formalization of the concept of agents in multivariate Markov chains. Agents are commonly defined as entities that act, perceive, and are goal-directed. In a multivariate Markov chain (e.g. a ... -
Adaptation of Kohonen feature map topologies by genetic algorithms
Polani, D.; Uthmann, T. (Elsevier, 1992)The following paper presents simulational results of coupling Genetic Algorithms to the Kohonen Feature Map paradigm. The Genetic Algorithm is used to improve the Kohonen Net topology, thus yielding better adaptation to ... -

Adaptive human-robot interaction based on lag-lead modelling for home-based stroke rehabilitation : Novel mechanisms for assessment and performance based adaptation of task difficulty
Basteris, A.; Amirabdollahian, Farshid (Institute of Electrical and Electronics Engineers (IEEE), 2013)In this work we present three interaction algorithms developed under the EU project SCRIPT in order to evaluate stroke patients' capabilities, evaluate their performance during robot-assisted exercise and consequently adapt ... -
Adaptive Robot Mediated Upper Limb Training Using Electromyogram Based Muscle Fatigue Indicators
Thacham-Poyil, Azeemsha; Steuber, Volker; Amirabdollahian, Farshid (2020-05-29)Studies on improving the adaptability of upper limb rehabilitation training do not often consider the implications of muscle fatigue sufficiently. In this study, electromyogram features were used as fatigue indicators in ... -
Adaptive training algorithm for robot-assisted upper-arm rehabilitation, applicable to individualised and therapeutic human-robot interaction
Chemuturi, Radhika; Amirabdollahian, Farshid; Dautenhahn, K. (2013-09)Rehabilitation robotics is progressing towards developing robots that can be used as advanced tools to augment the role of a therapist. Rehabilitation robots are capable of not only offering more frequent and more accessible ... -
Affordable robot mapping using omnidirectional vision
Bamorovat Abadi, Mohammad; Shahabian Alashti, Mohamad Reza; Holthaus, Patrick; Menon, Catherine; Amirabdollahian, Farshid (EPSRC UK-RAS Network, 2021-07-15)Mapping is a fundamental requirement for robot navigation.In this paper, we introduce a novel visual mapping method that relies solely on a single omnidirectional camera.We present a metric that allows us to generate a map ... -
The AI Settlement Generation Challenge in Minecraft : First Year Report
Salge, Christoph; Green, Michael Cerny; Canaan, Rodrigo; Skwarski, Filip; Fritsch, Rafael; Brightmoore, Adrian; Ye, Shaofang; Cao, Changxing; Togelius, Julian (2020-03-01)This article outlines what we learned from the first year of the AI Settlement Generation Competition in Minecraft, a competition about producing AI programs that can generate interesting settlements in Minecraft for an ... -
Algebraic analysis of the computation in the Belousov-Zhabotinsky reaction
Dini, P.; Nehaniv, C.L.; Egri-Nagy, A.; Schilstra, M. (Springer Nature, 2012)We analyse two very simple Petri nets inspired by the Oregonator model of the Belousov-Zhabotinsky reaction using our stochastic Petri net simulator. We then perform the Krohn-Rhodes holonomy decomposition of the automata ... -
All Else Being Equal Be Empowered
Klyubin, A.S.; Polani, D.; Nehaniv, C.L. (2005)The classical approach to using utility functions suffers from the drawback of having to design and tweak the functions on a case by case basis. Inspired by examples from the animal kingdom, social sciences and games we ... -
Analysis of EEG Microstates During Execution of a Nine Hole Peg Test
Alingal Meethal, Shadiya; Steuber, Volker; Amirabdollahian, Farshid (2023-04-28)Abstract—EEG microstates are brief periods of time during which the brain’s electrical activity remains stable. The analysis of EEG microstates can help to identify the background neuronal activity at the millisecond level. ... -
Analysis of the adapted inclusive haptic rigs for non-sighted people using duration and collision metrics
Bowers, Lisa; Amirabdollahian, Farshid (Springer Nature, 2014)In this demonstration we present a haptic digital rig, which offers an inclusive adapted version ofWade’s Nine Hole Peg Test (NHPT) [3]. After a manual NHPT, practice participantswill be requested to complete a nine hole ... -

Apparent actions and apparent goal-directedness
Polani, D.; Biehl, Martin (2015-07)In human history countless phenomena have been (wrongly) attributed to agents. For instance, now science believes there are no gods (agents) of lightning, thunder and wind behind the associated phenomena. In physics (assuming ... -
