Detecting Anomalies to Improve Data Center Efficiency

Complex high-performance computing systems are complex and require sophisticated tools for data center efficiency. This work describes a system for analyzing, visualizing, and interpreting large volume streaming data. For more information, see Data Center Facility Monitoring with Physics Aware ApproachHigh Performance Computing (2023). 

Downsampling Large Data Sets

This project proposes an algorithm to select data points from large and high-dimensional data sets to achieve data reduction with minimal information loss. It is achieved by approximating the data probability density function with a specific emphasis on rare data points. It enables efficient data summarization and data-efficient machine learning. 

Invertible Neural Network for Airfoils

This work developed a specialized invertible neural network (INN) model that learns a two-way mapping between airfoil shape parameters and aerodynamic/structural performance metrics. The INN framework enables high-fidelity aerodynamic effects to be captured in wind turbine blade design cycles that often require rapid design iterations under changing target specifications.
