Optimality of FDMA in Gaussian Multiple-Access Channels with Non-zero SNR Margin and Gap
— This paper investigates the effect of non-zero SNR margin and coding gap on the maximum sum rate and achievable rate region of the Gaussian Multiple-Access Channel (MAC). Frequ...

Max-margin Clustering: Detecting Margins from Projections of Points on Lines
Given a unlabelled set of points X ∈ RN belonging to k groups, we propose a method to identify cluster assignments that provides maximum separating margin among the clusters. We...

Polyhedral conditions for the nonexistence of the MLE for hierarchical log-linear models
We provide a polyhedral description of the conditions for the existence of the maximum likelihood estimate (MLE) for a hierarchical log-linear model. The MLE exists if and only if...

Board-Laying Techniques Improve Local Search in Mixed Planning and Scheduling
When searching the space of possible plans for combined planning and scheduling problems we often reach a local maximum and must either backtrack or otherwise modify the plan to m...
