A group of engineers and scientists at the University of Wisconsin-Madison have developed AI that is made from only a piece of glass with no sensors, circuits, or power sources. This is based on the same technology used for facial recognition in today’s smartphones, but it is much more simple. Professor of Electrical and Computer Engineering, Zongfu Yu, commented on the new research that has been published in Photonics Research.
“We’re using optics to condense the normal setup of cameras, sensors, and deep neural networks into a single piece of thin glass.”
As of now, AI uses a lot of computational resources and energy for things like facial recognition. With this new technology, the simple sheet of glass could possibly do the same thing but with absolutely no power source.
This exciting new AI is multiple pieces of glass that look like translucent squares. Within this glass are bubbles and other small impurities that are spread throughout certain locations. These work by bending light so that it can detect certain images. Instead of using codes, this glass is able to work with analog material only.
“We’re accustomed to digital computing, but this has broadened our view…The wave dynamics of light propagation provide a new way to perform analog artificial neural computing.” says Zongfu Yu.
Since this new type of AI glass does not rely on any type of power, circuits, or internet, it can last much longer. According to the engineers and scientists, there’s no reason to believe that one piece of glass couldn’t last for thousands of years.
According to Yu, “We could potentially use the glass as a biometric lock, tuned to recognize only one person’s face…Once built, it would last forever without needing power or internet, meaning it could keep something safe for you even after thousands of years.”
If implemented into something like a smartphone, this technology would drastically improve the battery life since the phone would no longer have to dedicate large amounts of energy to things like facial recognition. To top it all off, the piece of glass is an inexpensive creation.
The engineers and researchers at the University of Wisconsin-Madison figured out a way to take glass pieces and use them to identify written numbers. Light came from one of the written numbers and into the sheet of glass On the other side, there were nine spots that correspond to different digits. The light then focused on one of those as it moved through the glass. The engineers and scientists kept adjusting the location of the bubbles and impurities by small movements. After thousands of alterations, the glass was able to detect when a handwritten #3 was changed to a #8.
The engineers now want to push this further and try to get it to work with things like facial recognition. This technology could really change the way AI operates, and it could play a big role in the development of more complex systems in the future.
According to Ming Yuan, a Professor of Statistics at Columbia University who worked with the researchers, “The true power of this technology lies in its ability to handle much more complex classification tasks instantly without an energy consumption…These tasks are the key to create artificial intelligence; to teach driverless cars to recognize a traffic signal, to enable voice control in consumer devices, among numerous other examples.”
If this technology keeps getting developed further, it could really change the way some of our AI operates. The possibilities are endless when you have a simple sheet of glass that can perform the complex actions of something like facial recognition technology.
Artificial Intelligence Used to Prevent Icebergs from Disrupting Shipping
Experts at the University of Sheffield have developed a combination of control systems and artificial intelligence (AI) forecasting models to prevent icebergs from drifting into busy shipping regions.
Through the use of a recently published control systems model, experts were able to predict the movement of icebergs. In 2020, between 479 and 1,015 icebergs are expected to drift into waters south of 48°, an area that sees great shipping movement between Europe and north-east North America. Last year, there were a total of 1,515 observed in that same area.
The team relied on experimental artificial intelligence analysis in order to independently support the number of icebergs predicted. They also discovered a rapid early rise in the number of icebergs present in this area during the ice season, which runs from January to September.
The International Ice Patrol (IIP) is supplied with the findings, and they use the information to figure out the best use of resources for better ice forecasts during the season. According to the seasonal forecast, ships in the north-west Atlantic will be less likely to encounter an iceberg compared to last year.
Icebergs cause serious problems and shipping risks in the north-west Atlantic. Records show that there have been collisions and sinkings dating back to the 17th century. The IIP was established in 1912 after the sinking of the Titanic, and its job is to observe sea ice and conditions in the north-west Atlantic and warn of potential dangers.
The risk of icebergs to shipping changes each year. One year can see no icebergs crossing the area, while another year can see over 1,000. This makes it difficult to predict, but in general, there has been a higher amount detected since the 1980s.
2020 is the first year that artificial intelligence is being used to forecast the icebergs in the area, as well as the rate of change across the season.
The model was developed by a team led by Professor Grant Bigg at the University of Sheffield, and it was funded by insurance firm AXA XL’s Ocean Risk Scholarships Programme. There is a control systems model as well as two machine learning tools that are used.
Data related to the surface temperature of the Labrador Sea is analyzed, as well as variations in atmospheric pressure in the North Atlantic and the surface mass balance of the Greenland ice sheet.
The foundation control systems approach had an 80 percent accuracy level when tested against data on iceberg numbers for the seasons between 1997 and 2016.
According to some of Professor Bigg’s earlier research, the variation of the number of icebergs drifting into the region was due to variable calving rates from Greenland. However, the regional climate and ocean currents are the biggest factors. Higher numbers of icebergs appear when there are colder sea surface temperatures and stronger northwesterly winds.
Grant Brigg is a Professor of Earth System Science at the University of Sheffield.
“We have issued seasonal ice forecasts to the IIP since 2018, but this year is the first time we have combined the original control system model with two artificial intelligence approaches to specific aspects of the forecast. The agreement in all three approaches gives us the confidence to release the forecast for low iceberg numbers publicly this year—but it is worth remembering that this is just a forecast of iceberg conditions, not a guarantee, and that collisions between ships and icebergs do occur even in low ice years.”
According to Mike Hicks of the International Ice Patrol, “The availability of a reliable prediction is very important as we consider the balance between aerial and satellite reconnaissance methods.”
Dr. John Wardman is a Senior Science Specialist in the Science and Natural Perils team at AXA XL.
“The impact of sea level rise on coastal exposure and a potential increase in Arctic shipping activity will require a greater number and diversity of risk transfer solutions through the use of re/insurance products and other ‘soft’ mitigation strategies. The insurance industry is keeping a keen eye on the Arctic, and this model is an important tool in helping the industry identify how or when the melting Greenland Ice Sheet will directly impact the market.”
Cerebras Has the “World’s Fastest AI Computer”
According to the startup Cerebras Systems, the CS-1 is the world’s most powerful AI computer system. It is the latest attempt to create the best supercomputer, and it has been accepted by the U.S. federal government’s supercomputing program.
The CS-1 uses an entire wafer instead of a chip, and their computer design has many little cores across the wafer. There are over 1.2 trillion transistors across the cores of one wafer, which is a lot more than the 10 million that are often on one chip of a processor. If that wasn’t enough, the CS-1 supercomputer has six of the Cerebras wafers in one system. They are called a Wafer Scale Engine.
Cerebras’ first CS-1 was sent to the U.S. Department of Energy’s Argonne National Laboratory. The 400,000 cores will be used to work on extremely difficult AI computing problems like studying cancer drug interactions. The Argonne National Lab is one of the world’s top buyers of supercomputers.
The CS-1 is programmable with the Cerebras Software Platform and can be used with existing infrastructure, according to the startup. The Wafer Scale Engine (WSE) has more silicon area than the biggest graphics processing unit, and the 400.000 Sparse Linear Algebra Compute (SLAC) cores are flexible, programmable, and optimized for neural networks.
The CS-1 has a copper-colored block, or cold plate, that conducts heat away from the giant chip. Pipes of cold water are responsible for cooling, and fans blow cold air to carry heat away from the pipes.
According to many, the big breakthrough is the dashboard. Argonne has been constantly working on spreading out a neural net over large numbers of individual chips, making them better to program compared to other supercomputer machines like Google’s Pod.
The Cerebras CS-1 is basically one giant, self-contained chip where the neural network can be placed. A program has been developed to optimize the way math operations of a neural network are spread across the WSE’s circuits.
According to Rick Stevens, Argonne’s associate laboratory director for computing, environment, and life sciences, “We have tools to do this but nothing turnkey the way the CS-1 is, [where] it’s all done automatically.”
Built From the Ground Up
According to Cerebras, they are the only startup to build a dedicated system from the ground up. In order to achieve its amazing performance, Cerebras optimized every aspect of chip design, system design, and software of the CS-1 system. This allows the CS-1 to complete AI tasks that normally take months in minutes.
The supercomputer machine also greatly reduces training time, and single image classification can be completed in microseconds.
According to an interview given to the technology website VentureBeat, CEO of Cerebras Andrew Feldman said, “This is the largest square that you can cut out of a 300 millimeter wafer.” he continued, “Even though we have the largest and fastest chip, we know that an extraordinary processor is not necessarily sufficient to deliver extraordinary performance. If you want to deliver really fast performance, you need to build a system. And you can’t take a Ferrari engine and put it in a Volkswagen to get Ferrari performance. What you do is you move the bottlenecks if you want to get a 1,000 times performance gain.”
After the introduction of the CS-1 system, Cerebras have positioned themselves as one of the leaders in the supercomputer industry. Their contribution will undoubtedly have a major impact in solving some of the world’s most pressing AI challenges. These systems are drastically decreasing the time it will take to tackle many problems.
Microsoft Partners with Startup Graphcore to Develop AI Chips
Microsoft hopes that its Azure cloud platform will catch up in popularity with Amazon and Google, so as Wired reports, it has partnered with a British startup Graphcore to come up with a new computer chip that would be able to sustain all-new artificial intelligence developments.
As Wired notes, Bristo, UK startup Graphcore “has attracted considerable attention among AI researchers—and several hundred million dollars in investment—on the promise that its chips will accelerate the computations required to make AI work.” Since its inception in 2016, this is the first time that the company is publicly coming up with its chips and testing results.
Microsoft’s invested in Graphcore in December 2018 “as a part of a $200 million funding round”, as it wants to stimulate the use of its cloud services to a growing number of customers that use AI applications.
Graphcore itself designed its chips from scratch “to support the calculations that help machines to recognize faces, understand speech, parse language, drive cars, and train robots.” The company expects that its chips will be used by “companies running business-critical operations on AI, such as self-driving car startups, trading firms, and operations that process large quantities of video and audio, as well as those working on next-generation AI algorithms.”
According to the benchmarks published by Microsoft and Graphcore on November 13, 2019, “the chip matches or exceeds the performance of the top AI chips from Nvidia and Google using algorithms written for those rival platforms. Code is written specifically for Graphcore’s hardware maybe even more efficient.”
The two companies also stated that “certain image-processing tasks work many times faster on Graphcore’s chips,” and that “ they were able to train a popular AI model for language processing, called BERT, at rates matching those of any other existing hardware.”
Moor Insights AI chip specialist Karl Freund is of the opinion that the results of the new chip show that it is “cutting-edge but still flexible,” and that “they’ve done a good job making it programmable,” an extremely hard thing to do.
Wired further adds that Nigel Toon, co-founder, and CEO of Graphcore, says the companies began working together a year after his company’s launch, through Microsoft Research Cambridge in the UK. He also told the publication that his company’s chips are especially well-suited to tasks that involve very large AI models or temporal data. Also, one customer in finance supposedly saw a 26-fold performance boost in an algorithm used to analyze market data thanks to Graphcore’s hardware.
Some other, smaller companies used this occasion to announce that “they are working with Graphcore chips through Azure.” This includes Citadel, which will use the chips to analyze financial data, and Qwant, a European search engine that wants the hardware to run an image-recognition algorithm known as ResNext.
