Developing a Community LanguagePDF
Abstract We describe simulations of a community of agents who live in an environment which has some structure that the agents can learn to identify and subsequently about which they learn to communicate. Each agent has two entirely separate articial neural networks ...
An Exploration of Signalling Behaviour by both Analytic and Simulation Means for both Discrete and Continuous ModelsPDF
Abstract Kurd's (1995) model of a discrete actionresponse game, in which the interests of signallers and receivers conflict, is extended to address games in which, as well as signal cost varying with signaller quality, the value of an observer's response to a signal is also ...
Generating vowel systems in a population of agentsPDF
Abstract: In the sound systems of human languages remarkable universals are found. These universals can be explained by innate mechanisms, or by their function in human speech. This paper presents a functional explanation of certain universals of vowel systems using ...
Grounding adaptive language games in robotic agentsPDF
The paper addresses the question how a group of physically embodied robotic agents may origi- nate meaning and language through adaptive language games. The main principles underlying the approach are sketched as well as the steps needed to implement these principles on physical ...MORE ⇓
The paper addresses the question how a group of physically embodied robotic agents may origi- nate meaning and language through adaptive language games. The main principles underlying the approach are sketched as well as the steps needed to implement these principles on physical agents. Some experimen- tal results based on this implementation are presented.
Social coordination and spatial organization: Steps towards the evolution of communicationPDF
Abstract Traditional characterizations of communication as a biological phenomenon are theoretically criticized, and an alternative understanding is presented in terms of recursive action coordination following works on cybernetics and autopoiesis. As first steps towards ...
Too many love songs: Sexual selection and the evolution of communicationPDF
ECAL97, pages 434-443, 1997
Communication signals in many animal species (including humans) show a surprising amount of variety both across time and at any one instant in a population. Traditional accounts and simulation models of the evolution of communication offer little explanation of this diversity. ...MORE ⇓
Communication signals in many animal species (including humans) show a surprising amount of variety both across time and at any one instant in a population. Traditional accounts and simulation models of the evolution of communication offer little explanation of this diversity. Sexual selection of signals used to attract mates, and the coevolving preferences used to judge those signals, can instead provide a convincing mechanism. Here we demonstrate that a wide variety of ``songs'' can evolve when male organisms sing their songs to females who judge each male's output and decide whether or not to mate with him based on their own coevolved aesthetics. Evolved variety and rate of innovation are greatest when females combine inherited song preferences with a desire to be surprised. If females choose mates from a small pool of candidates, diversity and rate of change are also increased. Such diversity of communication signals may have implications for the evolution of brains as well.
Usage-based Structuralization of Relationships between WordsPDF
ECAL97, pages 483--492, 1997
Abstract The development of structure of relationships between words is studied with a constructive approach by means of arti cial agents with grammar systems. The agents try to recognize given sentences in terms of their own grammar. A word's relationship to other ...
Learning, culture and evolution in the origin of linguistic constraintsPDF
ECAL97, pages 493-502, 1997
Abstract This paper presents a computational model of language learning, transmission, and evolution. We contrast two explanations for the observed t of language universals with language function that are prominent in the linguistics literature, and which appear to rely ...
