PowerWise Patents Machine Learning Algorithm

PowerWise, through its Chief Technology Officer, Curtis Meadow, received United States Patent 10,489,716, Method for performing automated analysis of sensor data time series, at the end of 2019.

New Technique for Fast Data Analysis

Sensors and meters collect important information about buildings and mechanical systems. The amount of data can be staggering, especially for large buildings across multiple locations. Analyzing these large data sets could take weeks or months. To help recognize normal equipment operating states vs. problematic behavior, PowerWise patented a unique algorithm. This analytical tool can provide the results much faster than traditional methods.

Real-Time Machine Learning

The new method, known as Fast Data Analysis and Response (FADAR), is a self-learning system based on a modified data analysis algorithm called K-means clustering. The algorithm finds an optimal solution for the value K that accurately represents the normal operating state. The carefully-designed sequence of iterations on large amounts of live streaming data provides an exceptionally efficient method to determine complex patterns.

FADAR learns from incoming data over a period of about 30 days, analyzing the data clusters during the server’s quiet periods to determine normal operating states. After the learning period, FADAR can recognize deviations from normal operation in real-time as data comes in, a process tens of thousands of times faster than current analytical methods.

“We have always managed and analyzed huge amounts of data at PowerWise,” says Curtis Meadow. “I created FADAR to help our customers with predictive analytics for their important business equipment and decisions”.

Meadow received his Bachelors and Masters in Computer Science from UMaine, initiating a career in database development, software development, natural-language processing, university teaching, and novel algorithm design.
