Research in neuroscience has seen a recent trend toward the extension of receptive field (RF) estimation techniques and theoretical principles from linear to non-linear models. This development has ...

Invariant polynomials with matrix arguments have been defined by the theory of group representations, generalizing the zonal polynomials. They have developed as a useful tool to evaluate certain ...

We analyze two popular semidefinite programming relaxations for quadratically constrained quadratic programs with matrix variables. These relaxations are based on vector lifting and on matrix lifting; ...
