Conditional independence testing via weighted partial copulas and nearest neighbors

Pascal Bianchi, Kevin Elgui, François Portier

This paper introduces the \textit{weighted partial copula} function for testing conditional independence. The proposed test procedure results from these two ingredients: (i) the te…

Convergence of constant step stochastic gradient descent for non-smooth non-convex functions

Pascal Bianchi, Walid Hachem, Sholom Schechtman

This paper studies the asymptotic behavior of the constant step Stochastic Gradient Descent for the minimization of an unknown function F , defined as the expectation of a non conv…
