Moment varieties for mixtures of products
The setting of this article is nonparametric algebraic statistics. We study moment varieties of
conditionally independent mixture distributions on. These are the secant varieties of toric …

A Universal Formula For Counting Cubic Surfaces
A Deopurkar, A Patel, D Tseng - arXiv preprint arXiv:2109.12672, 2021 - arxiv.org
Using equivariant geometry, we find a universal formula that computes the number of times
a general cubic surface arises in a family. As applications, we show that the PGL (4) orbit …
