Hashing with binary autoencoders

, 2015
An attractive approach for fast search in image databases is binary hashing, where each high-dimensional, real-valued image is mapped onto a low-dimensional, binary vector and the search is done in this binary space.

Beam Orientation Optimization for Intensity Modulated Radiation Therapy using Adaptive l1 Minimization

, 2011
Beam orientation optimization (BOO) is a key component in the process of IMRT treatment planning. It determines to what degree one can achieve a good treatment plan quality in the subsequent plan optimization process.

Global Optimization for Value Function Approximation

, 2010
Existing value function approximation methods have been successfully used in many applications, but they often lack useful a priori error bounds. We propose a new approximate bilinear programming formulation of value function approximation, which employs

Model Reduction using a Frequency-Limited H2-Cost

, 2012
We propose a method for model reduction on a given frequency range, without the use of input and output filter weights. The method uses a nonlinear optimization approach to minimize a frequency limited H2 like cost function.

On Solving Convex Optimization Problems with Linear Ascending Constraints [PDF]

, 2014
In this paper, we propose two algorithms for solving convex optimization problems with linear ascending constraints. When the objective function is separable, we propose a dual method which terminates in a finite number of iterations.
