Apple ML Study Compares Supervised Versus Self-Supervised Learning

Andrew Orr ·

A research team at Apple published a study in October examining supervised and self-supervised algorithms. The title is “Do Self-Supervised and Supervised Methods Learn Similar Visual Representations?” From the abstract:

We find that the methods learn similar intermediate representations through dissimilar means, and that the representations diverge rapidly in the final few layers. We investigate this divergence, finding that it is caused by these layers strongly fitting to the distinct learning objectives. We also find that SimCLR’s objective implicitly fits the supervised objective in intermediate layers, but that the reverse is not true.

Time For The Apple Watch to Separate From The iPhone

Charlotte Henry ·

The Apple Watch Series 7 became available to order on Friday. In the latest edition of his ‘Power On’ newsletter, Bloomberg News‘s Mark Gurman noted how the wearable has got closer to breaking free from the iPhone but isn’t there yet.

Seven years into the Apple Watch era, one of Apple’s most promising device categories still does things the old way. As any Apple Watch owner knows, an iPhone is required for activation and setup, syncing data and day-to-day operating. The Apple Watch doesn’t meet the Jobs vision for every Apple device being able to operate and exist on its own. Apple has taken some steps over the years to push the Apple Watch in that direction, though… Despite those enhancements, you still can’t buy an Apple Watch, set it up from the device itself, and move over all of your content from the cloud. That limits the potential user base of the Apple Watch—and excludes people who might want to only own an Apple Watch and a Mac or iPad and no iPhone. Or, one day, people who want an Apple Watch as their only device.
