Edge AI (Artificial Intelligence at the Edge)
2 What is Edge AI?
Edge AI refers to deploying artificial intelligence algorithms directly on devices located at the “edge” of the network close to the data source rather than in centralized cloud servers. These devices can process data locally, often in real-time, without relying on constant internet connectivity.
Examples: Smartphones, drones, cameras, IoT devices, autonomous vehicles, wearable health monitors.
3 Core Technologies Enabling Edge AI
1 TinyML: Machine learning optimized for microcontrollers and low-power devices.
2 Edge TPUs and NPUs: Specialized hardware accelerators (e.g., Google Edge TPU, NVIDIA Jetson, Apple Neural Engine).
