New memristor training method slashes AI energy use by six orders of magnitude
In a Nature Communications study, researchers from China have developed an error-aware probabilistic update (EaPU) method that aligns memristor hardware’s noisy updates with neural network training, slashing energy use by nearly six orders of magnitude versus GPUs while boosting accuracy on vision tasks. The study validates EaPU on 180 nm memristor arrays and large-scale simulations.
The breakthrough that makes robot faces feel less creepy
Humans pay enormous attention to lips during conversation, and robots have struggled badly to keep up. A new robot developed at Columbia Engineering learned realistic lip movements by watching its own reflection and studying human videos online. This allowed it to speak and sing with synchronized facial motion, without being explicitly programmed. Researchers believe this …

Listen Labs raises $69M after viral billboard hiring stunt to scale AI customer interviews
Alfred Wahlforss was running out of options. His startup, Listen Labs, needed to hire over 100 engineers, but competing against Mark Zuckerberg’s $100 million offers seemed impossible. So he spent $5,000 — a fifth of his marketing budget — on a billboard in San Francisco displaying what looked like gibberish: five strings of random numbers. …

Meta’s Layoffs Leave Supernatural Fitness Users in Mourning
Users of the VR fitness service are distraught that Supernatural has had its staff cut and won’t receive any more content updates. They’re also pissed at Meta.
AIs behaving badly: An AI trained to deliberately make bad code will become bad at unrelated tasks, too
Artificial intelligence models that are trained to behave badly on a narrow task may generalize this behavior across unrelated tasks, such as offering malicious advice, suggests a new study. The research probes the mechanisms that cause this misaligned behavior, but further work must be done to find out why it happens and how to prevent …
Two Thinking Machines Lab Cofounders Are Leaving to Rejoin OpenAI
The news is a blow for Thinking Machines Lab. Two narratives are already emerging about what happened.
Generative AI tool helps 3D print personalized items that withstand daily use
Generative artificial intelligence models have left such an indelible impact on digital content creation that it’s getting harder to recall what the internet was like before it. You can call on these AI tools for clever projects such as videos and photos—but their flair for the creative hasn’t quite crossed over into the physical world …
