On straight words and minimal permutators in finite transformation semigroups.
(Springer, 2011)
Motivated by issues arising in computer science, we investigate the loop-free paths from the identity transformation and corresponding straight words in the Cayley graph of a finite transformation semigroup with a fixed ...
Impoverished empowerment : `meaningful' action sequence generation through bandwidth limitation
(2011)
Empowerment is a promising concept to begin explaining how some biological organisms may assign apriori values expectations to states in taskless scenarios. Standard empowerment samples the full richness of an environment ...
Think globally, sense locally : From local information to global features
(Institute of Electrical and Electronics Engineers (IEEE), 2011)
Shannon's information theory can be used to quantify morphological and topological features of a collective of agents in an arbitrary environment. In particular the ability of individual agents to extract information locally ...
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 ...
Evolving robot controllers in PDL using genetic programming
(Institute of Electrical and Electronics Engineers (IEEE), 2011)
We demonstrate how autonomous agents can be evolved whose controllers are programs in the dynamical systems-oriented, behaviour-based PDL language introduced by Luc Steels. Controllers evolved using a physics simulator ...
From babbling towards first words : The emergence of speech in a robot in real-time interaction
(Institute of Electrical and Electronics Engineers (IEEE), 2011)
This paper describes a system that simulates word form acquisition without meaning as a preliminary stage in language acquisition, through interaction with a human teacher. The system extracts phonemes from the teacher's ...
Robots that say 'no'
(2011-01-01)
This paper reports on foundational considerations for experiments into the acquisition of human-like use and understanding of negation in linguistic utterances via a developmental robotics approach. For this purpose different ...
Evolving Sims's creatures for bipedal gait
(Institute of Electrical and Electronics Engineers (IEEE), 2011-01-01)
In this paper we describe the design of an approach to evolve Sims's creatures with morphology and behaviour similar to biped animals. Our hypothesis is that biases in morphology that encourage limb specialisation, combined ...
Contingency allows the robot to spot the tutor and to learn from interaction
(Institute of Electrical and Electronics Engineers (IEEE), 2011-01-01)
Aiming at artificial system learning from a human tutor elicit tutoring behavior, which we implemented on the robotic platform iCub. For the evaluation of the system with users, we considered a contingency module that is ...
Towards using prosody to scaffold lexical meaning in robots
(Institute of Electrical and Electronics Engineers (IEEE), 2011)
We present a case-study analysing the prosodic contours and salient word markers of a small corpus of robot-directed speech where the human participants had been asked to talk to a socially interactive robot as if it were ...
