A Gradient Descent Trust Region Optimizer

Published in The Insight Journal - 2011 July-December.

Submitted by Rupert Brooks on 08-11-2011.

This document describes a new simple gradient descent optimizer which is a potential
replacement or supplement for RegularStepGradientDescentOptimizer. The optimizer requires only the gradient of the parameters and uses a simple linear model internally. However, it follows the theoretical basis of a trust-region algorithm and is able to achieve greater efficiency on certain image registration cases.
