A Christoffel-like function for high-dimensional support inference in graphical models

Jean-Bernard Lasserre, Lucas Slot

Christoffel polynomials are classical tools from approximation theory. They can be used to estimate the (compact) support of a measure $I^¼$ on $R^{d}$ based on its low-degre…

Gaussian mixtures closest to a given measure via optimal transport

Jean-Bernard Lasserre

Given a determinate (multivariate) probability measure $I^¼$ , we characterize Gaussian mixtures $I^½_I ¨ $ which minimize the Wasserstein distance $W_2 (I^¼, I^½_I ¨ )$ to $I^¼$ when the m…
