Center node: "overcomplete tensor decomposition via convex optimization"
  Abstract: Tensors provide natural representations for massive multi-mode datasets and tensor methods also form the backbone of many machine learning, signal processing, and statistical algorithms. The utility of tensors is mainly due to the ability to identify overcomplete, non-orthogonal factors from tensor data, which is known as tensor decomposition. This work develops theories and computational methods for guaranteed overcomplete, non-orthogonal tensor decomposition using convex optimization. We consider tensor decomposition as a problem of measure estimation from moments. We develop the theory for guaranteed decomposition under three assumptions: (i) Incoherence; (ii) Bounded spectral norm; and (iii) Gram isometry. We show that under these three assumptions, one can retrieve tensor decomposition by solving a convex, infinite-dimensional analog of $\ell_1$ minimization on the space of measures. The optimal value of this optimization defines the tensor nuclear norm that can be used to regularize tensor inverse problems, including tensor completion, denoising, and robust tensor principal component analysis. Remarkably, all the three assumptions are satisfied with high probability if the rank-one tensor factors are uniformly distributed on the unit spheres, implying exact decomposition for tensors with random factors. We also present and numerically test two computational methods based respectively on Burer-Monteiro low-rank factorization reformulation and the Sum-of-Squares relaxations.
