Apple has always been one of the more secretive companies in Silicon Valley, especially with their self-driving car effort. The Apple has always refused to confirm the existence of its work on self-driving cars, although there is a lot of circumstantial evidence that the company is working in the field.
Apple took a couple of steps recently to confirm its work in autonomous vehicles, though. According to Quartz:
Apple, unsurprisingly, is working on a lot of the same problems as other companies that are exploring machine learning: recognizing and processing images, predicting user behavior and events in the physical world, modeling language for use in personal assistants, and trying to understand how to deal with uncertainty when an algorithm can’t make a high-confidence decision.
Apple has been long-rumored to be building an autonomous vehicle, even sending a letter to the US National Highway Traffic Safety Administration (NHTSA) saying that companies looking to test autonomous vehicles should be treated the same, whether they are new to the field or more established self-driving car shops like Google and Uber.
