Do Motifs Reflect Evolved Function? – No Convergent Evolution of Genetic Regulatory Network Subgraph Topologies
(2008-10)
Methods that analyse the topological structure of networks have recently become quite popular. Whether motifs (subgraph patterns that occur more often than in randomized networks) have specific functions as elementary ...
Hierarchical coordinate systems for understanding complexity and its evolution with applications to genetic regulatory networks
(2008)
Beyond complexity measures, sometimes it is worth in addition investigating how complexity changes structurally, especially in artificial systems where we have complete knowledge about the evolutionary process. Hierarchical ...
Human to robot demonstrations of routine home tasks: exploring the role of the robot's feedback
(2008)
In this paper, we explore some conceptual issues, relevant for the design of robotic systems aimed at interacting with humans in domestic environments. More specifically, we study the role of the robot's feedback (positive ...
Computational memory architectures for autobiographic agents interacting in a complex virtual environment : a working model
(2008)
In this paper, we discuss the concept of autobiographic agent and how memory may extend an agent's temporal horizon and increase its adaptability. These concepts are applied to an implementation of a scenario where agents ...
Discriminating coding, non-coding and regulatory regions using rescaled range and detrended fluctuation analysis
(2008-01)
In this paper we analyse the efficiency of two methods, rescaled range analysis and detrended fluctuation analysis, in distinguishing between coding DNA, regulatory DNA and non-coding non-regulatory DNA of Drosophila ...
Teaching robot companions : The role of scaffolding and event structuring
(2008)
For robots to be more capable interaction partners they will necessarily need to adapt to the needs and requirements of their human companions. One way that the human could aid this adaptation may be by teaching the robot ...
Communication and complexity in a GRN-based multicellular system for graph colouring
(2008)
Artificial Genetic Regulatory Networks (GRNs) are interesting control models through their simplicity and versatility. They can be easily implemented, evolved and modified, and their similarity to their biological counterparts ...
Anticipating future experience using grounded sensorimotor informational relationships
(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 ...
Naturally occurring gestures in a human-robot interaction teaching scenario
(2008)
This paper describes our general framework for the investigation of how human gestures can be used to facilitate the interaction and communication between humans and robots. Two studies were carried out to reveal which ...
