For most of its 125-year history, the lighting industry has been about as low-tech as technology gets. Until the last few years, that is, when beautiful blue, green, and purple light-emitting diodes started flooding the market and showing up in everything from traffic signals to video billboards.

Nowadays, they light up huge bridges, add pizazz to casinos, and illuminate highly stylized interior spaces. And that’s just the beginning. To see how LEDs are going to be used tomorrow, you have to look to engineers like Frederick M. (“Fritz”) Morgan. As vice president of engineering at Color Kinetics Inc., in Boston, he has conjured up revolutionary lighting installations from Hollywood to Hong Kong.

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.
