Moment Identifiability of Homoscedastic Gaussian Mixtures
Daniele Agostini, Carlos Améndola, Kristian Ranestad
We consider the problem of identifying a mixture of Gaussian distributions with same unknown covariance matrix by their sequence of moments up to certain order. Our approach rests…
Discrete Gaussian distributions via theta functions
Daniele Agostini, Carlos Améndola
We study a discrete analogue of the classical multivariate Gaussian distribution. It is supported on the integer lattice and is parametrized by the Riemann theta function. Over the…
Algebraic Identifiability of Gaussian Mixtures
Carlos Améndola, Kristian Ranestad, Bernd Sturmfels
We prove that all moment varieties of univariate Gaussian mixtures have the expected dimension. Our approach rests on intersection theory and Terracini's classification of defectiv…
