DESCRIPTION:Title: <a href="https://researchseminars.org/talk/AAIT/7/">Eco
 nomy of vocal repertoires: Zipf's laws in animal communication</a>\nby Vla
 d Demartsev (Max Planck Institute of Animal Behavior) as part of Seminar o
 n Algorithmic Aspects of Information Theory\n\n\nAbstract\nZipf's Law of B
 revity (negative correlation of words' length with the frequency of their 
 use) was found across multiple lexicons and text corpora and often claimed
  to be one of unifying features of human language. This intriguing linguis
 tic regularity could be explained by the Principle of Least Effort — a c
 ompromise between the need for transferring information in a detailed and 
 comprehensive manner and the pressure for minimising the effort (cost) ass
 ociated with producing signals. If Zipf's principles are indeed fundamenta
 l for communication we should be able to find them in animal systems. Anim
 al communication systems are likely to be are constrained by the same fund
 amental trade-off between minimizing signalling costs while maintaining in
 formational integrity. However\, the pressure towards optimization of sign
 alling is not the only force shaping animal vocal repertoires. Factors lik
 e\, sexual selection\, social organization and habitat features can genera
 te evolutionary forces which might push vocal repertoires further away fro
 m Zipfian optimization.\n
