Bayes and Darwin: How replicator populations implement Bayesian computations
BioEssays: Problems & Paradigms
Dániel Czégel et. al.: “Bayesian learning theory and evolutionary theory both formalize adaptive competition dynamics in possibly high-dimensional, varying, and noisy environments. What do they have in common and how do they differ? We point out mathematical equivalences between their basic dynamical equations, generalizing the isomorphism between Bayesian update and replicator dynamics. We discuss how these mechanisms provide analogous answers to the challenge of adapting to stochastically changing environments at multiple timescales. A unified view of the theories of learning and evolution comes in sight.”
The newsletter now has a dedicated homepage where we post the cover artwork for each issue. We encourage submissions that coincide with the release of a recent paper from your group.
Caption: The artwork represents our recent study on population dynamics of Epithelial-Mesenchymal heterogeneity in cancer cells. Our in-silico model considers the asymmetric distribution of the EMT-inducing transcription factor SNAIL during cell division to cause spontaneous phenotypic switching. Generating a single clone from a mesenchymal cell (top left bar-plot) leads to a heterogeneous (Epithelial, Hybrid, and Mesenchymal) population over one in-silico cell passage (top right bar-plot). Upon several such passages (bottom row), the cell population converges to an Epithelial dominated phenotypic distribution. Our results suggest asymmetric cell division as a mechanism that can explain some of the findings reported in PMC42-LA breast cancer cells (click here).
