Automatically inferring user demographics from social media posts is useful for both social science research and a range of downstream applications in marketing and politics.

We apply non-linear methods for regression, i.e. Gaussian Processes, achieving strong correlation between ...

In this article we introduce the notion of textit{Fractal $omega$-operad} emerging from a natural $omega$-operad associated to any coglobular object in the category of higher operads in Batanin's sense, which in fact is a coendomorphism $omega$-operads. We have in mind coglobular object of higher operads which algebras are kind of higher transformations. It follows that this natural $omeg...
