Dictionary Learning and Tensor Decomposition via the Sum-of-Squares Method
We give a new approach to the dictionary learning (also known as “sparse coding”) problem of recovering an unknown n × m matrix A (for m ≥ n) from examples of the form [y = Ax + e], where x is a random vector in R[superscript m] with at most τ m nonzero coordinates, and e is a random noise vector in...
