Bio-logic: gene expression and the laws of combinatorial logic
(2008)
At the heart of the development of fertilized eggs into fully formed organisms and the adaptation of cells to changed conditions are genetic regulatory networks (GRNs). In higher multi-cellular organisms, signal selection ...
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 ...
On preferred states of agents: how global structure is reflected in local structure
(MIT Press, 2008)
We investigate the correlation between the information theoretic measure of empowerment and the graph theoretic measure of closeness centrality, to better understand the structural conditions that must exist in a world for ...
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 ...
Keep Your Options Open : An Information-Based Driving Principle for Sensorimotor Systems
(2008)
The central resource processed by the sensorimotor system of an organism is information. We propose an information-based quantity that allows one to characterize the efficiency of the perception-action loop of an abstract ...
Algebraic properties of automata associated to Petri nets and applications to computation in biological systems
(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 ...
