Hello,
A new submission has been added to the Insight Journal.

Title: A Gradient Descent Trust Region Optimizer
Author(s):Brooks R.
Abstract: 
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.
