Properties of the Log-Barrier Function on Degenerate Nonlinear Programs
We examine the sequence of local minimizers of the log-barrier function for a nonlinear program near a solution at which second-order sufficient conditions and the Mangasarian-From...

Robust Regression with Asymmetric Heavy-Tail Noise Distributions
In the presence of a heavy-tail noise distribution, regression becomes much more di cult. Traditional robust regression methods assume that the noise distribution is symmetric and...

Anisotropic Imaging Of Tumours Using Elastic Wave Signals
—In this short paper we show how one may extract elastic properties of materials by probing it with elastic waves and processing the signal that returns (i.e. the scattered waves...

Exact Decoding of Phrase-Based Translation Models through Lagrangian Relaxation
This paper describes an algorithm for exact decoding of phrase-based translation models, based on Lagrangian relaxation. The method recovers exact solutions, with certificates of...
