Abstract：Abstract. We provide a systematic convergence analysis of the Hessian operator estimator from random samples supported on a low dimensional manifold. We show that the impact of the nonuniform sampling and the curvature on the widely applied Hessian operator estimator is asymptotically negligible. This is joint work with Hau-Tieng Wu (Courant Institute of Mathematical Sciences, NYU).
