Algebraic identifiability in independent component analysis mixture models
A research talk by Pardis Semnani (MPI MiS, Leipzig) as part of the Seminar on Nonlinear Algebra, examining independent component analysis (ICA) mixture models — nonparametric extensions of Gaussian mixtures built from convex combinations of ICA densities. The talk establishes when the defining parameters of such densities, including mixing coefficients, linear transformations and source moments,
