We’ve developed a simple meta-learning algorithm called Reptile which works by repeatedly sampling a task, performing stochastic gradient descent on it, and updating the initial parameters towards the final parameters learned on that task. This method performs as well as MAML, a broadly applicable meta-learning algorithm, while being simpler to implement and more computationally efficient.

Could the development of eyesight-improving eyedrops help eliminate the need for glasses? Quite possibly, suggests new research coming out of Israel’s Shaare Zedek Medical Center and Bar-Ilan University. A team of ophthalmologists at these institutes have invented and tested “nanodrops” which, combined with a laser process, reportedly results in improvements in both short- and long-sightedness.

Learning has an evolutionary purpose: Among species, individuals that adapt to their environments will succeed. That’s why your brain more easily retains important or surprising information: It takes very little effort to remember that the neighbor’s dog likes to bite. Remembering the dog’s name is harder.

New research published today by Cairney and his colleagues in Current Biology has made significant headway on this issue by linking sleep spindles—spontaneous bursts of brain activity—to memory processing in a sleeping brain. Incredibly, the researchers claim it is possible to determine the content of the memory being processed by analyzing this brain activity.
