Fascinating video about a system that teaches a drone to fly around urban environments using data from cars and bikes as training data. There’s a paper here and code here. It’s a great example of leveraging CNNs in embedded environments. I believe that moving AI and ML to the edge and ultimately into devices such as IoT sensors is going to be very important. Having dumb sensor networks and edge devices just means that an enormous amount of worthless data has to be transferred into the cloud for processing. Instead, if the edge devices can perform extensive semantic mining of the raw data, only highly salient information needs to be communicated back to the core, massively reducing bandwidth requirements and also allowing low latency decision making at the edge.
Take as a trivial example a system of cameras that read vehicle license plates. One solution would be to send the raw video back to somewhere for license number extraction. Alternately, if the cameras themselves could extract the data, then only the recognized numbers and letters need to be transferred, along with possibly an image of the plate. That’s a massive bandwidth saving over sending constant compressed video. Even more interesting would be edge systems that can perform unsupervised learning to optimize performance, all moving towards eliminating noise and recognizing what’s important without extensive human oversight.
