    • Spectral Methods from Tensor Networks 

      Moitra, Ankur; Wein, Alexander S (Society for Industrial & Applied Mathematics (SIAM), 2023-04-30)
      A tensor network is a diagram that specifies a way to “multiply” a collection of tensors together to produce another tensor (or matrix). Many existing algorithms for tensor problems (such as tensor decomposition and tensor ...

    • Coupling Techniques for Nonlinear Ensemble Filtering 

      Spantini, Alessio; Baptista, Ricardo; Marzouk, Youssef (Society for Industrial & Applied Mathematics (SIAM), 2022-11)
      We consider filtering in high-dimensional non-Gaussian state-space models with intractable transition kernels, nonlinear and possibly chaotic dynamics, and sparse observations in space and time. We propose a novel filtering ...

    • Lifting for Simplicity: Concise Descriptions of Convex Sets 

      Fawzi, Hamza; Gouveia, Joao; Parrilo, Pablo A; Saunderson, James; Thomas, Rekha R (Society for Industrial & Applied Mathematics (SIAM), 2022-11)
      This paper presents a selected tour through the theory and applications of lifts of convex sets. A lift of a convex set is a higher-dimensional convex set that projects onto the original set. Many convex sets have lifts ...
