Professor Saltzman introduces the material properties of elasticity and viscosity. He describes two separate experimental setups to measure the elasticity and the viscosity of a material. Material elasticity can be defined in terms of stress-strain property, and defines the Young’s modulus (E), ...

Training conditional maximum entropy models on massive data sets requires significant computational resources, but by distributing the computation, training time can be significant reduced. Recent theoretical results have demonstrated conditional maximum entropy models trained by weight mixtures...

In this paper, we explore an application of basis pursuit to audio scene analysis. The goal of our work is to detect when certain sounds are present in a mixed audio signal. We focus on the regime where out of a large number of possible sources, a small but unknown number combine and overlap t...
