Genetic Code Degeneracy: Implications for Grammatical Evolution and BeyondPDF
ECAL99, pages 149-153, 1999
Grammatical Evolution (GE) is a grammar-based GA which generates computer programs. GE has the distinction that its input is a BNF, which permits it to generate programs in any language, of arbitrary complexity. Part of the power of GE is that it is closer to natural DNA ...

This paper is concerned about the origin of pheromone communication in complex societies, eg, colonies of real ants and bees. The aim of the work is to study whether pheromone communication among artificial ant agents in a cooperative foraging scenario can arise ...

Males may use sexual displays to signal their quality to females; the handicap principle provides a mechanism that could enforce honesty in such cases. Iwasa et al.[1] model the signalling of inherited male quality, and distinguish between three variants of the ...

This paper describes a model for the evolution of communication systems using simple syntactic rules, such as word combinations. It also focuses on the distinction between simple word-object associations and symbolic relationships. The simulation method combines ...
Emergence of speech sounds in changing populationsPDF
ECAL99, pages 664-673, 1999
This paper shows that realistic and coherent vowel systems can emerge from scratch in a population of agents that imitate each other under human-like constraints of production and perception. The simulation is extended so that populations can change; old agents can be ...

This paper addresses the emergence of a common phonetic code in a society of communicating speech agents using evolutionary techniques. Predictions for the large vowel systems of the world's languages using the Maximum Use of Available distinctive ...

We report on a case study in the emergence of a lexicon in a group of autonomous distributed agents situated and grounded in an open environment. Because the agents are autonomous, grounded, and situated, the possible words and possible meanings are not ...
Analyzing the Evolution of Communication from a Dynamical Systems PerspectivePDF
ECAL99, pages 689-693, 1999
We study the evolution of communication where concepts are developed individually by agents and relations between concepts and forms (words, signals) are learned through interaction with other agents. By constructing concepts based on experience with the ...

A new approach to the origins of syntax in human language is presented. Using computational models of populations of learners, it is shown that compositional, recursive mappings are inevitable end-states of a cultural process of linguistic transmission. This is ...

Some recent Artificial Life models have attempted to explain the origin of linguistic diversity with varying conclusions and explanations. We posit, contrary to some existing Artificial Life work, that linguistic diversity should naturally emerge in spatially organised ...MORE ⇓

What permits some systems to evolve and adapt more effectively than others? Gell-Mann [3] has stressed the importance of ``com- pression'' for adaptive complex systems. Information about the environ- ment is not simply recorded as a look-up table, but is rather compressed in a theory or schema. Several conjectures are proposed: (I) compression aids in generalization; (II) compression occurs more easily in a ``smooth'', as opposed to a ``rugged'', string space; and (III) constraints from com- pression make it likely that natural languages evolve towards smooth string spaces. We have been examining the role of such compression for learning and evolution of formal languages by artificial agents. Our sys- tem does seem to conform generally to these expectations, but the trade- oobetween compression and the errors that sometimes accompany it need careful consideration.

Multiple agents, equipped with a feature-based phonetic model and a connectionist cognitive model, interact via the naming game paradigm, such that lexicon formation and change is an emergent property of this complex adaptive system. Our system converges ...

The naming game is a formal mechanism that describes the development of a lexicon in a society of culturally interacting agents. We will here use a cellular automaton version of this game to study the influence of an extra-linguistic structure over the evolution of the lexicon ...MORE ⇓

Categorization dynamics as the clustering of words in word relation is studied by a constructive approach which is suited to inquire evolutionary linguistics with dynamical view on language. Word meaning is represented by relationship among words. Tthe ...
