Geologic Carbon Storage (GCS) is an important technology that aims to reduce the amount of carbon dioxide in the atmosphere. Multiphase flow in porous media is essential to understand CO2 migration and pressure fields in the subsurface associated with GCS. However, numerical simulation for such problems in 4D is computationally challenging and expensive, due to the multiphysics and multiscale nature of the highly nonlinear governing partial differential equations (PDEs). It prevents us from considering multiple subsurface scenarios and conducting real-time optimization. Here, we develop a Fourier-enhanced multiple-input neural operator (Fourier-MIONet) to learn the solution operator of the problem of multiphase flow in porous media. Fourier-MIONet utilizes the recently developed framework of the multiple-input deep neural operators (MIONet) and incorporates the Fourier neural operator (FNO) in the network architecture. Once Fourier-MIONet is trained, it can predict the evolution of saturation and pressure of the multiphase flow under various reservoir conditions, such as permeability and porosity heterogeneity, anisotropy, injection configurations, and multiphase flow properties. Compared to the enhanced FNO (U-FNO), the proposed Fourier-MIONet has 90% fewer unknown parameters, and it can be trained in significantly less time (about 3.5 times faster) with much lower CPU memory (< 15%) and GPU memory (< 35%) requirements, to achieve similar prediction accuracy. In addition to the lower computational cost, Fourier-MIONet can be trained with only 6 snapshots of time to predict the PDE solutions for 30 years. The excellent generalizability of Fourier-MIONet is enabled by its adherence to the physical principle that the solution to a PDE is continuous over time.


Microsoft Warns That "1984" May Come True in Three Years Time

#artificialintelligence

George Orwell's 1984 has made waves in the cultural world, even if it's someone comparing the dystopian novel to why they can't buy a breakfast meal after 11 am. However, Microsoft believes that real-life technology may soon replicate Big Brother's in the coming years. Microsoft's president, Brad Smith, made the somewhat scary prediction on BBC Panorama. In it, the UK news giant explored how China uses artificial intelligence to keep an eye on its citizens. Smith said that the government needs to keep up-to-date on how technology can spy on people and create laws to protect citizens' privacy as it develops.


How Artificial Intelligence Could Help Power NASA's Artemis Mission to the Moon and Beyond.

#artificialintelligence

On December 11th 2017, President Trump signed Space Policy Directive 1, refocusing NASA's efforts in human space exploration. In March 2019, Vice President Mike Pence made the surprising announcement that America would be returning astronauts to the Moon in just 5 years time. This Lunar mission, known as Artemis which stands for "Acceleration, Reconnection, Turbulence and Electrodynamics of Moon's Interaction with the Sun", is hoping to leave more than just a flag and footprints this time. NASA aims to establish a base on the Moon and in orbit by 2028, providing a foundation for where scientists will eventually power a mission to Mars and beyond. The Artemis mission has left many questioning whether it is possible to send human's back to the Moon in just five years time, with a report claiming that NASA would need an annual increase of $4-$5 billion on top of its $22.6 billion 2020 budget.


How artificial intelligence will do our dirty work, take our jobs and change our lives

#artificialintelligence

At its crudest, most reductive, we could sum up the future of artificial intelligence as being about robot butlers v killer robots. We have to get there eventually, so we might as well start with the killer robots. If we were to jump forward 50 years to see what artificial intelligence might bring us, would we – Terminator-style – step into a world of human skulls being crushed under the feet of our metal and microchip overlords? No, we're told by experts. It might be much worse.


In 50 years we'll have 'robot angels' and will be able to merge our brains with AI, according to technology experts

#artificialintelligence

Brian Wong - Kiip, CEO & Co-founder: So in 50 years I think the world will, in terms of technology, really change and really this concept I call proximity of tech - which is how close the technology is to your body. And right now where it's kind of silly, we hold things and we wear things and it's kind of at our hands, right? And we might put it on over our faces but the whole point is just getting it into our eyeballs, into our ears, into our stomachs. Ingestibles are already a thing, it's crazy, you literally ingest these pills these robot pills that can obviously see what you're eating and all these things and all your caloric intake, it's amazing. And then you know you've heard of startups like Magic Leap where they're doing AR for your world; I should just be able to load my emails then like do this, then do this, that's literally what will happen I think in 50 years, everything will just come inside and that to me is really, really exciting.


Could new technology transform the NHS?

#artificialintelligence

How could the NHS look in another 30 years time? Will new technology and medical advances transform how we're looked after? We asked nine different corners of the health service - and the health secretary - what innovations we might see. Innovations that were unthinkable only a few decades or years ago are now common practice. Advances in medicine and technology, such as robot-assisted surgery and artificial intelligence, will have a significant impact on the delivery of surgical care in the future.


You could talk to your dog in ten years time

Daily Mail - Science & tech

In just ten years time your dog could talk to you instead of barking, according to leading experts. Advances in artificial intelligence and machine learning mean the Dr Dolittle dream of communicating with animals could soon be a reality. One researcher is currently collecting thousands of videos of dogs barking, growling and moving around, and is using them to teach an algorithm to understand canine communication. Professor Con Slobodchikoff from Northern Arizona University is developing new technology that interprets the calls of the prairie dog and says it could eventually be used to interpret other animals. North American rodents prairie dogs have a sophisticated ways of calling group members and alerting them to danger.

In 2018 A.I. will enter the SME tech stack – Touchpoints.ai – Medium

#artificialintelligence

We have been in the market of analytics for roughly 10 years now. The product we have to today is no older than 2,5 years. Along the journey we were blessed to work with many of the brightest and most experienced people in the field of actually applying analytics in the domain of marketing. These professionals were able to lever the value in the data of their companies way before many of their competitors could even grasp that there was something happening. The difference was that they could build their analytics stack with the software that was already available.


Algorithms will out-perform Doctors in just 10 years time - Dataconomy

#artificialintelligence

The power of Algorithms to calculate, contemplate and anticipate the needs of patients is improving rapidly and still has no sign of slowing down. Everything from patient diagnosis to therapy selection will soon be moving at exponential rates. Does that mean the end of doctors? To better understand technology's ever-growing role in healthcare, we first have to better examine the potential of tools and timelines that we are working with. A recent study done at Beth Israel Deaconess Medical Center (BIDMC) and Harvard Medical School, showed that AI isn't about Humans versus Machines. They trained a Deep Learning Algorithm for identifying Metastatic Breast Cancer, interpreting pathology images.


How Artificial Intelligence and other emerging technology might impact corporate travel

#artificialintelligence

Egencia has been taking a look at how technology such as artificial intelligence will effect the corporate travel world in the near, medium and long-term. Alongside Phocuswright, the Expedia-owned travel management company has put together a white paper entitled the "Emerging Tech-Driven Corporate Travel Revolution." The study provides a current state of the nation look as regards technologies such as AI, machine learning, Natural Language Processing and chatbots in business travel as well as looking further out. In three years time, for example, the research predicts AI will be embedded in corporate travel in terms of how data is used to make for smarter, more efficient travel and improved compliance. Natural language processing and chatbots are not expected to be fully embedded at this early stage.
