Optimization, Machine Learning and High Performance Computing

Group is directed by: Professor Oliveira and  Professor Stewart

2021 REU Mentors:  Professor Suely Oliveira
wi
th  Geoff Converse ,   Jamil Gafur  and  Tarun Roy

We bring knowledge from Numerical Analysis and Optimization to design and improve Machine Learning algorithms.

We focus on applications with large amounts of data where new optimization or parallel algorithms are essential.

Recent projects include: Machine Learning and Genetics, Neural Networks and Educational data, Theoretical Foundations of Neural Networks, Gerrymandering

Gradient descent simulation           Gravity Swarm Algorithm on convex plain
We study classical optimization methods, stochastic gradient descent, and metaheuristics for machine learning and their parallelization. Above, see simulations of gradient descent and a metaheuristic algorithm (image provided by Jamil Gafur, PhD student in Computer Science).

Recent Collaborators include: Professor Mariana Curi, Professor Jonathan Templin, Dr. Mariana Castanheira, Dr Scott Pu, Prof. Octav Chipara, Prof. Amaury Lendasse, Prof. Palle Jorgensen
