ISLE-members Robert Weibel and Balthasar Bickel are co-authors of the research article on "contact-tracing in cultural evolution: a Bayesian mixture model to detect geographic areas of language contact"
In the research article the authors tackle upon the question how geographical contact areas in language data can be found, while taking into account the confounding effects of inheritance and universal preference. They present sBayes, an algorithm for Bayesian clustering in the presence of confounding effects. The algorithm learns which similarities are better explained by confounders, and which are due to contact effects.
