PENG Session 13

Roland M¨ uhlenbernd Seminar f¨ ur Sprachwissenschaft University of T¨ ubingen

TO-DO: Scheine & Projects

◮ For Scheine: Final report

◮ program documentation (Core, GUI) ◮ theoretical background (signaling games, update dynamics...) ◮ basic results (experimental set-up, statistics)

◮ For ESSLLI: project abstracts

◮ standard message space (n-games, language death...) ◮ vowel space (3D; 2D & contact) ◮ complex messages, compositionality

Dynamic Class: input parameters & their meaning

Input parameters: DYNAMICPARAM

◮ posRe: value for positive reinforcement ◮ negRe: value for negative reinforcement ◮ startingValue: initial number of colored balls ◮ initNumBlackBalls: initial number of black balls ◮ lateralInhib: value for lateral inhibition ◮ minNumBalls: not used!!! ◮ maxNumBalls: stable content of the urn (by normalization)

Notes:

◮

initNumBlackBalls startingValue×|M+1| defines initial pressure for innovation

◮

posRe maxNumBalls defines degree of flexibility1

◮ The initial number of new messages is startingValue ◮

startingValue maxNumBalls defines initial proportion of new messages2

1same for negRe; lateralInhib must also be considered 2Initial number of new mes. m for given state t is raised by posRe-compl(m),

therefore posRe also influences initial proportion of new message m
