Achieving Corresponding Effects on Multiple Robotic Platforms: Imitating in Context Using Different Effect Metrics
Alissandrakis, A.; Nehaniv, C.L.; Dautenhahn, K.; Saunders, J. (The Society for the Study of Artificial Intelligence and the Simulation of Behaviour (AISB), 2005)One of the fundamental problems in imitation is the correspondence problem, how to map between the actions, states and effects of the model and imitator agents, when the embodiment of the agents is dissimilar. In our ... -
Action, State and Effect Metrics for Robot Imitation
Alissandrakis, A.; Nehaniv, C.L.; Dautenhahn, K. (Institute of Electrical and Electronics Engineers (IEEE), 2006)This paper addresses the problem of body mapping in robotic imitation where the demonstrator and imitator may not share the same embodiment (degrees of freedom (DOFs), body morphology, constraints, affordances and so on). ... -
Adaptation of the Perception-Action Loop Using Active Channel Sampling
Capdepuy, P.; Polani, D.; Nehaniv, C.L. (Institute of Electrical and Electronics Engineers (IEEE), 2008) -
The Agent-Based Perspective on Imitation
Dautenhahn, K.; Nehaniv, C.L. (MIT Press, 2002)This chapter presents the agent-based perspective on imitation. In this perspective, imitation is best considered as the behaviour of an autonomous agent in relation to its environment, including other autonomous agents. ... -
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 ... -
Algebraic connectivity

Algebraic hierarchical decomposition of finite state automata : comparison of implementations for Krohn-Rhodes Theory
Egri-Nagy, Attila; Nehaniv, C.L. (2005)The hierarchical algebraic decomposition of finite state automata (Krohn- Rhodes Theory) has been a mathematical theory without any computational implementations until the present paper, although several possible and ... -
Algebraic properties of automata associated to Petri nets and applications to computation in biological systems
Egri-Nagy, A.; Nehaniv, C.L. (2008)Biochemical and genetic regulatory networks are often modeled by Petri nets. We study the algebraic structure of the computations carried out by Petri nets from the viewpoint of algebraic automata theory. Petri nets comprise ... -
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 ... -
Anticipating future experience using grounded sensorimotor informational relationships
Mirza, N.A.; Nehaniv, C.L.; Dautenhahn, K.; Te Boekhorst, R. (MIT Press, 2008)Operational definitions and applications of the sensorimotor experience of an artificial embodied organism are presented along with a mathematical metric for distance between experiences based on Shannon information. We ... -
Applications Of Automata Theory And Algebra : Via The Mathematical Theory of Complexity to Biology, Physics, Psychology, Philosophy, and Games
Rhodes, John (World Scientific Publishing, 2010)This book was originally written in 1969 by Berkeley mathematician John Rhodes. It is the founding work in what is now called algebraic engineering, an emerging field created by using the unifying scheme of finite state ... -
An Approach for Programming Robots by Demonstration: Generalization Across Different Initial Configurations of Manipulated Objects
Alissandrakis, A.; Nehaniv, C.L.; Dautenhahn, K.; Saunders, J. (Institute of Electrical and Electronics Engineers (IEEE), 2005)Imitation is a powerful learning tool that can be used by a robotic agent to socially learn new skills and tasks. One of the fundamental problems in imitation is the correspondence problem, how to map between the actions, ... -
As time goes by: representing and reasoning about timing in human-robot interaction studies
Kose-Bagci, H.; Broz, F.; Shen, Q.; Dautenhahn, K.; Nehaniv, C.L. (AAAI, 2010)We summarise the experimental design issues related to timing in several human-robot interaction scenarios investigating turn-taking or synchronization between child-sized humanoid robots and human participants. Our aim1 ... -
An assertion concerning functionally complete algebras and NP-completeness
Horvath, G.; Nehaniv, C.L.; Czabo, C. (2008)In a paper published in J. ACM in 1990, Tobias Nipkow asserted that the problem of deciding whether or not an equation over a nontrivial functionally complete algebra has a solution is NP-complete. However, close examination ... -
Assessing the performance of different behavior selection architectures in a large and complex virtual environment
Ho, W.C.; Avila-Garcia, O.; Nehaniv, C.L. (Institute of Electrical and Electronics Engineers (IEEE), 2005)We compare the performance of autonomous agents with three different behavior selection architectures (Static-Threshold, Winner-Takes-All and Voting- Based) in terms of survival in a large and complex dynamic virtual ... -
Asynchronous automata networks can emulate any synchronous automata network

Automatic Analysis of Computation in BioChemical Reactions
Egri-Nagy, A.; Nehaniv, C.L.; Rhodes, J.L.; Schilstra, M. (2008)We propose a modeling and analysis method for biochemical reactions based on finite state automata. This is a completely different approach compared to traditional modeling of reactions by differential equations. Our method ... -
