I'm Derek Onken, a PhD student in the Computer Science and Informatics Program at Emory University. I focus on data-intensive problems, especially those with biological motivation. My strengths lie in mathematical approaches to data analysis.
(Such approaches include the following buzzwords: machine learning, deep learning, neural networks, big data, statistical analysis, GPUs, numerical optimization.)

Majors: Mathematics and Computer Science
Minors: Physics and Classical Culture
PDE-based Machine Learning with Lars Ruthotto . (2018 - present)
Applying knowledge of optimizers and partial differential equation solvers to machine learning architectures. More specifically, we ask if current reliance on gradient-based methods necessarily results in the most efficient training, question the stability of presented problems and the ability of current architectures to handle ill-posed problems, and view current architectures from a scientific computing perspective.
Parkinson's Disease Telemonitoring and Voice Analysis via Mobile App with Eugene Agichtein as part of his IRLAB. (2017)
Collecting and analyzing voice data, touch pressure, and rest tremor to detect Parkinson's disease symptoms via remote patient monitoring. Building machine learning classifier using motor and vocal features extracted from these patients.
Using CDR data from H1N1 outbreak to predict future disease outbreaks with Ymir Vigfusson in the Simbiosys Lab. (2016-2018)
Our dataset contians cellphone data from the H1N1 outbreak in 2009-2010 and linked health data. We develop a classifier to determine/predict sickness based on human behavior changes around Date of Diagnosis. Motivation: give health officials a more real-time and accurate estimation of sick individuals as an outbreak is occuring.
