"We study this graphical model from the perspectives of algebraic statistics and tropical geometry, starting with the observation that its Zariski closure is a Hadamard power of the first secant variety of the Segre variety of projective lines."

Look, if you don't know what that is right away just from the abstract I don't know how to help you...

... what with me having no clue either.

I've always disliked mathematics' proclivity for naming things after people. I don't have any better solution, but I still don't like it. Even things I do understand look like gibberish if it has three or four proper names like that.
