    Trading Accuracy for Sparsity in Optimization Problems with Sparsity Constraints
    Download  www.cs.huji.ac.il
    We study the problem of minimizing the expected loss of a linear predictor while constraining its sparsity, i.e., bounding the number of features used by the predictor. While the r...

    A Semidefinite Relaxation Scheme for Multivariate Quartic Polynomial Optimization with Quadratic Constraints
    Download  www.se.cuhk.edu.hk
    We present a general semidefinite relaxation scheme for general n-variate quartic polynomial optimization under homogeneous quadratic constraints. Unlike the existing sum-of-squar...
