Learned optimizers are algorithms that can be trained to solve optimization problems. Although learned optimizers can outperform baseline optimizers in restricted settings, the ML research community understands remarkably little about their inner workings or why they work as well as they do. In a paper currently under review for ICLR 2021, a Google Brain research team attempts to shed some light on the matter.
The researchers explain that optimization algorithms can be considered the basis of modern machine learning. A popular research area in recent years has focused on learning optimization algorithms by directly parameterizing and training an optimizer on a distribution of tasks.
Research on learned optimizers aims to replace the baseline “hand-designed” optimizers with a parametric optimizer trained on a set of tasks, which can then be applied more generally. In contrast to baseline optimizers that use simple update rules derived from theoretical principles, learned optimizers use flexible, high-dimensional, nonlinear parameterizations.
Elon Musk’s Boring Company received its first official “approval” for the expansion of its Vegas Loop. The city’s Planning Commission openly showed support for the Boring Co.’s project, recommending an approval for the expansion of the Vegas Loop to the City Council. Before the recommendation, the Planning Commission suggested adding a stop to the loop in the Arts District as well.
The Las Vegas Arts District—known as 18b—is a cultural hub, filled with enticing creative opportunities and sights to titillate imaginative, adventurous minds. It offers a different sort of entertainment than the casinos and resorts in Sin City. The Planning Commission seemed eager to support a stop in the Arts District for the Vegas Loop.
“We’re very excited to see the (Boring Company’s) application come forward. It’s a special thing. It’s exciting that its coming through downtown. I can see on the map all the different stops associated with the casinos and hotels going up and down,” said one commissioner who had visited Boring Company’s tunnels before voting on the motion.
HSC J023336-053022, a massive galaxy cluster located approximately 4 billion light-years away from Earth, is heating the material within it to hundreds of millions of degrees Celsius — over 25 times hotter than the core of the Sun.
Automated medical transcription that’s actually accurate could save doctors a huge amount of time, and the tech giants are getting in on the action.
A large team of researchers affiliated with a host of institutions in Italy, the U.K and Hungary has carried out the most precise measurements yet of deuterium fusing with a proton to form helium-3. In their paper published in the journal Nature, the group describes their effort and how they believe it will contribute to better understanding the events that transpired during the first few minutes after the Big Bang.
Astrophysics theory suggests that the creation of deuterium was one of the first things that happened after the Big Bang. Therefore, it plays an important role in Big Bang nucleosynthesis—the reactions that happened afterward that led to the production of several of the light elements. Theorists have developed equations that show the likely series of events that occurred, but to date, it has been difficult to prove them correct without physical evidence. In this new effort, the researchers working at the Laboratory for Underground Nuclear Astrophysics in Italy have carried out experiments to simulate those first few minutes, hoping to confirm the theories.
The work was conducted deep under the thick rock cover of the Gran Sasso mountain to prevent interference from cosmic rays —it involved firing a beam of protons at a deuterium target—deuterium being a form of hydrogen with just one proton and one neutron—and then measuring the rate of fusion. But because the rate of fusion is so low, the bombardment had to be carried out many times—the team carried out their work nearly every weekend for three years.

A group of researchers led by Sir Andre Geim and Dr. Alexey Berdyugin at The University of Manchester have discovered and characterized a new family of quasiparticles named ‘Brown-Zak fermions’ in graphene-based superlattices.
The team achieved this breakthrough by aligning the atomic lattice of a graphene layer to that of an insulating boron nitride sheet, dramatically changing the properties of the graphene sheet.
The study follows years of successive advances in graphene-boron nitride superlattices which allowed the observation of a fractal pattern known as the Hofstadter’s butterfly—and today (Friday, November 13) the researchers report another highly surprising behavior of particles in such structures under applied magnetic field.
Holographic displays that are both compact and produce realistic holograms without eyestrain are still difficult to realize. Here the authors implement a steering-backlight unit and a holographic video processor to produce a realistic holographic display in a slim panel.
Teaching birds to help us with recycling!
A very interesting approach! 😃
Who knew birds would be absolutely crushing it in the recycling game? If they can do it, so can you!
