Approximation of functions over redundant dictionaries using coherence

Anna C. Gilbert, S. Muthukrishnan, Martin J. Strauss

    Research output: Contribution to conferencePaperpeer-review


    An overview of algorithmic results for the basic problem in highly nonlinear approximation is presented. In particular, an efficient algorithm for near-optimal representation of input signals over μ-coherent dictionaries is introduced. Additionaly, insights into highly nonlinear approximation problems are provided.
