Hierarchical behaviours : getting the most bang for your bit
(2011)
Hierarchical structuring of behaviour is prevalent in natural and artificial agents and can be shown to be useful for learning and performing tasks. To progress systematic understanding of these benefits we study the effect ...
On the skeleton of a finite transformation semigroup
(2010)
There are many ways to construct hierarchical decompositions of transformation semigroups. The holonomy algorithm is especially suitable for computational implementations and it is used in our software package. The structure ...
Stochastic model of template-directed elongation processes in biology
(2010)
We present a novel modular, stochastic model for biological template-based linear chain elongation processes. In this model, elongation complexes (ECs; DNA polymerase, RNA polymerase, or ribosomes associated with nascent ...
Representations of time in symbol grounding systems
(AAAI, 2010)
This paper gives a short overview of time representations in current symbol grounding architectures. Furthermore we report on a recently developed embodied language acquisition system that acquires object words from a ...
Two Agents Acting as One
(MIT Press, 2010)
We consider two agents, each equipped with a controller. When they achieve a joint goal configuration, their coordination can be measured informationally. We show that the amount of coordination that two agents need to ...
Genetic algorithms and their application to in silico evolution of genetic regulatory networks
(2010)
A genetic algorithm (GA) is a procedure that mimics processes occurring in Darwinian evolution to solve computational problems. A GA introduces variation through "mutation" and "recombination" in a "population" of possible ...
Integration of Action and Language Knowledge: A Roadmap for Developmental Robotics
(2010)
This position paper proposes that the study of embodied cognitive agents, such as humanoid robots, can advance our understanding of the cognitive development of complex sensorimotor, linguistic, and social learning skills. ...
Preparing to talk : Interaction between a linguistically enabled agent and a human teacher
(AAAI, 2010)
As a precursor to learning to use language an infant has to acquire preliminary linguistic skills, including the ability to recognize and produce word forms without meaning. This develops out of babbling, through vocal ...
As time goes by: representing and reasoning about timing in human-robot interaction studies
(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 ...
What do You Want to do Today? : Relevant-Information Bookkeeping in Goal-Oriented Behaviour
(MIT Press, 2010)
We extend existing models and methods for the informational treatment of the perception-action loop to the case of goaloriented behaviour and introduce the notion of relevant goal information as the amount of information ...
