Fusion-Id: A Photoplethysmography and Motion Sensor Fusion Biometric Authenticator With Few-Shot on-Boarding

by AI Generated Robotic ContentFAANGPosted on Comments are Disabled

The abundance of wrist-worn heart rate measuring devices enables long term cardiovascular monitoring through photoplethysmography (PPG). Such signals contain unique identifiable information that can help in biometric authentication. In this work, we propose Fusion-ID, which use wrist-worn PPG sensors fused with motion sensor data as a way to do bio authentication on wrist worn devices. …

What Are Graph Neural Networks?

by AI Generated Robotic ContentFAANGPosted on Comments are Disabled

When two technologies converge, they can create something new and wonderful — like cellphones and browsers were fused to forge smartphones. Today, developers are applying AI’s ability to find patterns to massive graph databases that store information about relationships among data points of all sorts. Together they produce a powerful new tool called graph neural …
