Sleep Can Keep AI From Catastrophic Forgetting

New data-replay strategy prevents AI amnesia

Neural networks can achieve superhuman performance in many tasks, but these AI systems can suddenly and completely forget what they have learned if asked to absorb new memories. Now a new study reveals a novel way for neural networks to undergo sleep-like phases and help prevent such amnesia.

A major challenge that artificial neural networks face is "catastrophic forgetting." When they learn a new task, they have an unfortunate tendency to abruptly and entirely forget what they previously learned. Essentially, they overwrite past data with new knowledge.

IEEE Spectrum (Robots: Companies)

It’s been a couple of years, but the IEEE Spectrum Robot Gift Guide is back for 2022! We’ve got all kinds of new robots, and right now is an excellent time to buy one (or a dozen), since many of them are on sale this week. We’ve tried to focus on consumer robots that are actually available (or that you can at least order), but depending on when you’re reading this guide, the prices we have here may not be up to date, and we’re not taking shipping into account.

And if these robots aren’t enough for you, many of our picks from years past are still available: check out our guides from 2019, 2018, 2017, 2016, 2015, 2014, 2013, and 2012. And as always, if you have suggestions that you’d like to share, post a comment to help the rest of us find the perfect robot gift.

Learn how to measure and reduce common mode electromagnetic interference (EMI) in electric drive installations

Rohde & Schwarz

Nowadays, electric machines are often driven by power electronic converters. Even though the use of converters brings with it a variety of advantages, common mode (CM) signals are a frequent problem in many installations. Common mode voltages induced by the converter drive common mode currents damage the motor bearings over time and significantly reduce the lifetime of the drive.
