Research by computer scientists on how self-driving cars can better spot cyclists and pedestrians while using fewer sensors has been posted online, in what appears to be the company’s first publicly disclosed paper on autonomous vehicles. The paper by Yin Zhou and Oncel Tuzel, submitted on November 17 to independent online journal arXiv, is significant because Apple’s famed corporate secrecy around future products has been seen as a drawback among artificial intelligence and machine learning researchers. The scientists proposed a new software approach called “VoxelNet” for helping computers detect three-dimensional objects. declined to comment. Academics are used to freely sharing their work with peers at other organisations. Yielding to that dynamic, in July established the Machine Learning Journal for its researchers.

Their work rarely appears outside the journal, which so far has not published any research on self-driving cars. Self-driving cars often use a combination of normal two-dimensional cameras and depth-sensing “LiDAR” units to recognise the world around them. While the units supply depth information, their low resolution makes it hard to detect small, faraway objects without help from a normal camera linked to it in real time. But with new software, the researchers said they were able to get “highly encouraging results” in spotting pedestrians and cyclists with just LiDAR data. They also wrote they were able to beat other approaches for detecting three-dimensional objects that use only LiDAR. The experiments were computer simulations and did not involve road tests. Though Chief Executive has called self-driving cars “the mother of all AI projects,” has given few hints about the nature of its ambitious. Last December, told federal regulators it was excited about the technology and asked regulators not to restrict testing of the technology. In April, filed a testing plan with California regulators.
