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 flexibility 1 ◮ ◮ The initial number of new messages is startingValue startingValue maxNumBalls defines initial proportion of new messages 2 ◮ 1 same for negRe ; lateralInhib must also be considered 2 Initial 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
