If you ever wondered how Google’s self-driving car can tell drivers apart from cyclists and other users of the road, the company’s latest report on the project should shed a bit of light on the topic.It turns out that (as with many of the company’s products) machine learning algorithms figure heavily into the car’s detection technology.
