Testing the mixture model hypothesis via spectral gap
March T. Boedihardjo, Joe Kileel, Vandy Tombs
In this paper, we study the problem of testing whether or not a given probability measure on can be decomposed as a mixture of two probability measures whose s…

The effect of smooth parametrizations on nonconvex optimization landscapes
Eitan Levin, Joe Kileel, Nicolas Boumal
We develop new tools to study landscapes in nonconvex optimization. Given one optimization problem, we pair it with another by smoothly parametrizing the domain. This is either for…

Finding stationary points on bounded-rank matrices: A geometric hurdle and a smooth remedy
Eitan Levin, Joe Kileel, Nicolas Boumal
We consider the problem of provably finding a stationary point of a smooth function to be minimized on the variety of bounded-rank matrices. This turns out to be unexpectedly delic…
