Grab it Explore the intricacies of manifold learning with noisy data in this 43-minute lecture by Elisabeth Gassiat from LMO/Université Paris-Saclay. Delve into a general framework for recovering low-dimensional non-linear structures from high-dimensional data contaminated with significant, unknown noise. Examine minimax rates for support estimation using Hausdorff distance. Cover topics including dimension reduction, manifold learning concepts, geometric approaches to noisy data, additive noise examples, and support estimation through deconvolution with Gaussian noise. Investigate identifiability theorems, geometric conditions for high-dimensional data, and practical examples of supports. Gain valuable insights into estimation upper bounds and leave with a comprehensive understanding of manifold learning in the presence of noisy data.
