At a private workshop held this week for AI researchers, Apple researchers gave a rare glimpse of some machine learning technology they’re building for self-driving cars.
Speaking to an exclusive audience of researchers in the field, Ruslan Salakhutdinov, Apple’s director of AI, discussed several projects apparently related to automated driving.
The technical talks were given Friday, during the Neural Information Processing Systems conference, the largest AI-focused academic event of the year, which was held in Long Beach, California. The event attracted thousands of researchers including many from rival tech companies. The talks were designed to showcase Apple’s technical prowess and to woo potential recruits.
Salakdinov, who joined Apple in 2016 but who still holds a post as a professor at Carnegie Mellon University, showed off a project previously disclosed in a paper posted online by Apple last month. This project trained a system to recognize pedestrians and other vehicles from 3-D point cloud information.
Other projects not previously revealed included a method for classifying different objects on the road using cameras placed on top of a vehicle, and a method of using camera footage to track its position very precisely. This technique, known as visual SLAM (simultaneous location and mapping) could be used for autonomous driving but also augmented and virtual reality.

Apple has long been rumored to be working on automated driving. While the company hasn’t publicly acknowledged such a project, some details have leaked out. For example, the company has applied for a permit to test automated vehicles in California. Tim Cook, Apple’s CEO, has also all but confirmed the rumor, telling Bloomberg that the company is “focused on autonomous systems,” which he also described as “the mother of all AI projects.”
Carlos Guesterin, Apple’s director of machine learning and a professor at the University of Washington in Seattle, spoke after Salakhutdinov about several of the company’s large-scale machine learning efforts, including that behind the face-recognition system developed for the iPhone X.
Guesterin reassured researchers that working at Apple didn’t not mean you couldn’t publish research. He also announced that Apple was open-sourcing a tool called Turi Create that is designed to make machine learning easier. Guesterin joined Apple after his startup, Turi, was acquired last year.
Apple develops a range of machine learning technologies for its products, but the company still discloses only a tiny amount of its research compared with competitors like Google and Facebook. Apple usually avoids talking about its research as a way to avoid tipping competitors off about future products.
It says much about the current battle between tech companies for machine learning talent that Apple has abandoned this secretive culture and begun publishing machine learning research and discussing some projects more openly. Apple has even begun its own Machine Learning Journal, where it has published details of several AI-related projects.
Friday’s event attracted researchers from big universities and from big tech firms, including Google and Facebook. Nvidia, Uber, Microsoft, Facebook and others threw lavish parties during the conference that were packed with researchers. Not to be outdone, Apple put on its own mixer several hours after the technical talk.
