Like other parts of the Middle East, Iran is considered one of the cradles of civilization. With a written history that stretches over more than 7,000 years, it constitutes one of the most variegated and richest cultures of the region, if not the world. The significance of Iran's cultural heritage and history finds its expression in the twenty-four sites that are included among the UNESCO World Heritage Sites, with another fifty-six properties tentatively listed.

Compositional inductive biases in human function learning

This talk presents evidence that humans learn complex functions by harnessing compositionality: complex structure is decomposed into simpler building blocks. I formalize this idea in the framework of Bayesian nonparametric regression using a grammar over Gaussian process kernels, and compare this approach with other structure learning approaches. People consistently chose compositional (over non-compositional) extrapolations and interpolations of functions.
