Detecting COVID Cases with Deep Learning

When: Tuesday, June 9 at 10am PT / 1pm ET

Two months ago, University of Waterloo’s Vision and Image Processing (VIP) Lab and DarwinAI released a preprint of their COVID-Net research on designing a convolutional neural network for detecting COVID-19 from X-rays.  Last month, SigOpt launched SigOpt for Good, which extends free access to our product for any COVID-19 research. As part of this program, SigOpt collaborated with a member of the VIP lab to tune data augmentation parameters of COVID-Net to better understand how data augmentation plays a role in COVID-Net performance. 

In this talk, lead researcher Alexander Wong from DarwinAI discusses with Michael McCourt from SigOpt his insights on the design, development, optimization, and impact of COVID-Net. Among other topics, this discussion will cover:

  • Neural Network Design: Design considerations and the evolution of the neural network through the training and tuning processes
  • Deep Learning Optimization: Tradeoffs related to the parameter optimization process and how tuning data augmentation was integrated into the process
  • Real World Impact: How COVID-Net has been utilized and the way in which this has evolved over time

This talk is great for deep learning practitioners interested in a vision use case, researchers focused on health-related data, or anyone interested in learning about novel applications of deep learning to COVID-19 research. 

For any researcher interested in using SigOpt for free on their COVID work, please reach out to us here: https://tuning.sigopt.com/sigopt-for-good
