Cтуденческий семинар

В пятницу 19.11 в 18.00 на Соколе состоится студенческий семинар по моделированию в рамках НОЦ "Нейробиология и нейроинформатика" МИФИ.
Студент МИФИ Алексей Русаков расскажет о статье - Paenke, Ingo, Tadeusz J. Kawecki, и Bernhard Sendhoff. 2009. The Influence of Learning on Evolution: A Mathematical Framework. Artificial Life 15, Iss. 2: 227-245. doi:10.1162/artl.2009.15.2.15204.

The Baldwin effect can be observed if phenotypic learning influences the evolutionary fitness of individuals, which can in turn accelerate or decelerate evolutionary change. Evidence for both learning-induced acceleration and deceleration can be found in the literature. Although the results for both outcomes were supported by specific mathematical or simulation models, no general predictions have been achieved so far. Here we propose a general framework to predict whether evolution benefits from learning or not. It is formulated in terms of the gain function, which quantifies the proportional change of fitness due to learning depending on the genotype value. With an inductive proof we show that a positive gain-function derivative implies that learning accelerates evolution, and a negative one implies deceleration under the condition that the population is distributed on a monotonic part of the fitness landscape. We show that the gain-function framework explains the results of several specific simulation models. We also use the gain-function framework to shed some light on the results of a recent biological experiment with fruit flies.

Место: Балтийская д.8, 2 эт. комн. 184.
