Volume of quasi-homogeneous sublevel sets: Two linear algebra deterministic algorithms with convergence rates

Didier Henrion, Jean B Lasserre

We consider the problem of computing the Lebesgue volume of the unit sublevel set of a positive quasi-homogeneous polynomial. Pushing the Lebesgue measure of an ambient bounding bo…

Scalable anomaly detection via a univariate Christoffel function

Florian Grivet, Didier Henrion, Jean-Bernard Lasserre +1

Anomaly detection plays a critical role in identifying unusual patterns across domains such as fraud detection, network intrusion, and system fault diagnosis. Recently, Christoffel…

Gaussian-like fixed point and variational properties of integral discriminants

Jean B Lasserre

We consider partition functions Z(g) = exp (-g(x))dx where g is a nonnegative polynomial action (a degree-2n form) vanishing only at the origin. Such integrals, known as integral d…

Connecting max-entropy with computational geometry, LP and SDP

Jean B Lasserre

We consider the well-known max-(relative) entropy problem (y) = infQP DKL(Q P ) with Kullback-Leibler divergence on a domain R d , and with ''moment'' constra…
