Next month, however, a team of MIT researchers will be presenting a so-called âProxyless neural architecture searchâ algorithm that can speed up the AI-optimized AI design process by 240 times or more. That would put faster and more accurate AI within practical reach for a broad class of image recognition algorithms and other related applications.
âThere are all kinds of tradeoffs between model size, inference latency, accuracy, and model capacity,â says Song Han, assistant professor of electrical engineering and computer science at MIT. Han adds that:
â[These] all add up to a giant design space. Previously people had designed neural networks based on heuristics. Neural architecture search tried to free this labor intensive, human heuristic-based exploration [by turning it] into a learning-based, AI-based design space exploration. Just like AI can [learn to] play a Go game, AI can [learn how to] design a neural network.â

âThis is the first clear demonstration of controlling the speed of a pulse light in free space,â Abouraddy said in the statement. âAnd it opens up doors for many applications, an optical buffer being just one of them, but most importantly itâs done in a simple way, thatâs repeatable and reliable.â

A University of California Irvine student may have stumbled upon an invention to end your phone-charging woes for good. And thatâs just the tip of the iceberg of where that could take us as a society. Forget about your phone; the world would be a different place without ever having to worry about replacing car batteries, and imagine the uses that it could have in space exploration. Technology is the ultimate wildcard.
A battery that lasts a whole lifetime is now one step closer to becoming a reality thanks to Mya Le Thai, a PhD student whoâs been researching how to make better nanowire rechargeable batteries. In theory, her discovery could lead to a battery that lasts centuriesâas long as 400 years.
She made the discovery while studying the properties of gold nanowire for commercial batteries. Typically, the gold filaments lose their integrity (and the battery dies) after 5,000 to 6,000 recharge cyclesââseven thousand at the most,â adds Reginald Penner, head of the chemistry department, who called Thaiâs discovery âcrazy.â

Humans could build a permanent settlement on Mars where a new branch of human civilization and social order could be created, said a Mars exploration advocate on Thursday.
âWe could easily have humans on Mars in 10 years or faster if it is an international project,â Robert Zubrin, the Mars Society president, told the Global Times in an exclusive interview on Thursday in Beijing.
By then, human beings could go back and forth between Mars and Earth anytime by taking reusable rockets and the technology would be cheaper and cheaper as the spaceflight frequency to Mars increases, he said.

Recorded Live: 11/8/1975 â Winterland â San Francisco, CA
More Jefferson Starship at Music Vault: http://www.musicvault.com
Personnel:
Grace Slick â vocals
Paul Kantner â vocals, guitar
Marty Balin â vocals, percussion
David Frieberg â keyboards, bass, vocals.
Craig Chaquico â lead guitar
Pete Sears â bass, piano
Johnny Barbata â drums, vocals (on track #4)
Summary:
Recorded after the monumentally successful Red Octopus album release, but prior to 1976âs Spitfire album, this Jefferson Starship concert captures the band performing a diverse set before a hometown audience. With singer Marty Balin back in the fold, the group again contained the three primary vocalists from the Jefferson Airplane, now supported by vocalist, keyboardist, part-time bassist, and ex-Quicksilver Messenger Service member David Frieberg; the young guitar prodigy Craig Chaquico; and the superb rhythm section of bassist/pianist Pete Sears and drummer Johnny Barbata. The group was riding high on the multi-platinum Red Octopus album and was arguably at a new peak of popularity.
This set is not only represented by material from the early Jefferson Starship albums and a couple of Jefferson Airplane classics, but interestingly features live performances of material from Grace Slickâs first solo album plus two of the best tracks Marty Balin recorded with his post-Jefferson Airplane project, Bodacious D F.
From precision GPS to batteries for one of the worldâs first commercial all-electric airplanes, NASA technology turns up in nearly every corner of modern life. The latest edition of NASAâs Spinoff publication features dozens of commercial technologies that were developed or improved by the agencyâs space program and benefit people everywhere.
âNASA works hard, not only to develop technology that pushes the boundaries of aeronautics and space exploration, but also to put those innovations into the hands of businesses and entrepreneurs who can turn them into solutions for challenges we all face here on Earth,â said Jim Reuter, acting associate administrator of the agencyâs Space Technology Mission Directorate. âThese are sometimes predictable, like the many NASA technologies now adopted by the burgeoning commercial space industry, but more often they appear in places that may seem unrelated, like hospitals, farms, factories and family rooms.â
In this issue of Spinoff, the agency shares new stories of how:
