Optimization Methods for Machine Learning
Mathematics of Data & DecisionsSpeaker: | Roummel Marcia, UC Merced |

Machine learning (ML) problems are often posed as highly nonlinear and nonconvex unconstrained optimization problems. Methods for solving ML problems based on stochastic gradient descent generally require fine-tuning many hyper-parameters. In this talk we discuss alternative approaches for solving ML problems based on a quasi-Newton trust-region framework that does not require extensive parameter tuning. We will present numerical results that demonstrate the potential of the proposed approaches.
