Researchers have developed a low-power artificial intelligence system that can identify drones while using dramatically less electricity than conventional computer-based systems. If a drone-monitoring device relies on batteries, a power-hungry AI system can greatly reduce how long it can operate before it needs to be recharged. Testing showed that the system could accurately identify different types of drones as well as their flight status. At the same time, it reduced power consumption by 88.7% compared with running the AI system on a conventional CPU. The large reduction in electricity use could make the technology particularly valuable for surveillance systems that need to operate continuously.
