Alan Turing Institute to spend grants on AI for air traffic control and banking

Turns out the skies can be the limit for machine learning

The UK government will bankroll two major research projects led by the country's national institute for AI, the Alan Turing Institute: one to automate air traffic control, and the other for banking services.

Project Bluebird, arguably the more interesting of the two, will receive £11.9m and explore how techniques like reinforcement learning can be applied to coordinate the flight paths of aircraft. With fresh investment, the goal is to eventually conduct the world’s first live trials of an AI system capable of monitoring air traffic and communicating with pilots.

Researchers at the Alan Turing Institute have been working on this problem with NATS, Blighty’s biggest air traffic control provider, since 2018. It's hoped the machine-learning system can assist human controllers in preventing accidents and improving traffic flow. By optimizing journeys, the software may even reduce fuel consumption, too.

We're told the project will have three parts:

  • Develop a probabilistic digital twin of UK airspace: this real-time, physics-based computer model will predict future flight trajectories and their likelihoods – essential information for decision-making. It will be trained on a NATS dataset of at least 10 million flight records, and will take into account the many uncertainties in ATC, such as weather, or aircraft performance.
  • Build a machine learning system that collaborates with humans to control UK airspace: unlike current human-centric approaches, this system will simultaneously focus on both the immediate, high-risk detection of potential aircraft conflicts, and the lower risk strategic planning of the entire airspace, thus increasing the efficiency of ATC decision-making. To achieve this, researchers will develop algorithms that use the latest machine learning techniques, such as reinforcement learning, to optimise aircraft paths.
  • Design methods and tools that promote safe, explainable and trustworthy use of AI in air traffic control systems: this will involve experiments with controllers to understand how they make decisions, so that these behaviours can be taught to AI systems.

The aim, as far as we can tell, is not to outright replace human air traffic controllers, and instead get humans and intelligent machines working closer and better together.

“The project will explore ethical questions such as where the responsibility lies if a human-AI system makes a mistake, how to build a system that is trusted by humans, and how to balance the need for both safety and efficiency,” the institute said.

Some of the code for this project is open-source and already up on GitHub.

The second funded scheme is a £12.4m collaboration between the institute and HSBC dubbed Project FAIR. An interdisciplinary team made up of computer scientists and economists will investigate how AI can revamp financial services and tools, and look for the best ways to apply the technology fairly and securely.

Interestingly, the project will involve generating synthetic financial data for researchers to experiment with. Using real data is risky, and isn’t possible for privacy reasons.

“It aims to address challenges such as how to increase the accuracy of predictive models without compromising privacy and security of customers, or improving transparency without leaving systems open to external threats,” the project’s description read.

“The project intends to outline how the finance sector can make the transformational shift to the greater use of AI technologies, ensuring they have fairness, security and accountability at their heart, while being robust and aware of privacy.”

The funding comes from the Engineering and Physical Sciences Research Council, part of UK Research and Innovation, a government body working under the Department for Business, Energy and Industrial Strategy. ®

    DuckDuckGo promises privacy to users of its Android, iOS browsers, and macOS browsers – yet it allows certain data to flow from third-party websites to Microsoft-owned services.

    Security researcher Zach Edwards recently conducted an audit of DuckDuckGo's mobile browsers and found that, contrary to expectations, they do not block Meta's Workplace domain, for example, from sending information to Microsoft's Bing and LinkedIn domains.

    Specifically, DuckDuckGo's software didn't stop Microsoft's trackers on the Workplace page from blabbing information about the user to Bing and LinkedIn for tailored advertising purposes. Other trackers, such as Google's, are blocked.

  • Despite 'key' partnership with AWS, Meta taps up Microsoft Azure for AI work
    Someone got Zuck'd

    Meta’s AI business unit set up shop in Microsoft Azure this week and announced a strategic partnership it says will advance PyTorch development on the public cloud.

    The deal [PDF] will see Mark Zuckerberg’s umbrella company deploy machine-learning workloads on thousands of Nvidia GPUs running in Azure. While a win for Microsoft, the partnership calls in to question just how strong Meta’s commitment to Amazon Web Services (AWS) really is.

    Back in those long-gone days of December, Meta named AWS as its “key long-term strategic cloud provider." As part of that, Meta promised that if it bought any companies that used AWS, it would continue to support their use of Amazon's cloud, rather than force them off into its own private datacenters. The pact also included a vow to expand Meta’s consumption of Amazon’s cloud-based compute, storage, database, and security services.

  • Atos pushes out HPC cloud services based on Nimbix tech
    Moore's Law got you down? Throw everything at the problem! Quantum, AI, cloud...

    IT services biz Atos has introduced a suite of cloud-based high-performance computing (HPC) services, based around technology gained from its purchase of cloud provider Nimbix last year.

    The Nimbix Supercomputing Suite is described by Atos as a set of flexible and secure HPC solutions available as a service. It includes access to HPC, AI, and quantum computing resources, according to the services company.

    In addition to the existing Nimbix HPC products, the updated portfolio includes a new federated supercomputing-as-a-service platform and a dedicated bare-metal service based on Atos BullSequana supercomputer hardware.
