*Title:* Bolstering Stochastic Gradient Descent with Model Building

*Abstract:* Stochastic gradient descent method and its variants constitute
the core optimization algorithms that achieve good convergence rates for
solving machine learning problems. These rates are obtained especially when
these algorithms are fine-tuned for the application at hand. Although this
tuning process can require large computational costs, recent work has shown
that these costs can be reduced by line search methods that iteratively
adjust the stepsize. In this talk, we will introduce an alternative
approach to stochastic line search by using a new algorithm based on
forward step model building. This model building step incorporates a
second-order information that allows adjusting not only the stepsize but
also the search direction.

This is a joint work with S. I. Birbil, G. Onay, and F. Öztoprak.
