Approximately achieving Gaussian relay network capacity with lattice codes
Abstract--Recently, it has been shown that a quantize-mapand-forward scheme approximately achieves (within a constant number of bits) the Gaussian relay network capacity for arbitr...

Scaling Laws and Local Minima in Hebbian ICA
We study the dynamics of a Hebbian ICA algorithm extracting a single non-Gaussian component from a high-dimensional Gaussian background. For both on-line and batch learning we fin...
