New statistical test for Gaussian random fields introduced
Researchers have introduced a novel statistical concept called the "second maximum" of a Gaussian random field on a Riemannian manifold. This statistic, defined as the largest value of the field away from its global max…

New method offers certified early stopping for AI regularized inverse problems
Researchers have developed a method for certified early stopping in regularized inverse problems, which involves trading off a data-fidelity term against a regularizer. This approach utilizes an exact duality-gap identi…

New bounds for random fields applied to Tensor PCA and spin models
Researchers have developed new non-asymptotic tail bounds for the Kostlan--Shub--Smale (KSS) random field on the sphere. These bounds are applied to problems in Spiked Tensor PCA and the complexity of the spherical $k$-…

New method smooths policies for combinatorial optimization
Researchers have developed a new method to improve the training of policies for combinatorial optimization problems by adding controlled random perturbations. This smoothing technique makes the empirical risk differenti…
