Satellite Imagery + Social Media = A New Way to Spot Emerging Nuclear Threats

BY PATRICK TUCKER

A research team is training computers to find and fuse clues from wildly different rivers of digital data.

Hiding illicit nuclear programs might be getting harder, thanks to new ways of gleaning and combining clues from various rivers of digital data. That's the conclusion of new research funded in part by the U.S. Energy Department's National Nuclear Security Administration.

Satellites offer one kind of information; social media another — particularly inside countries that may be trying to flout inspections. But large volumes of satellite imagery and social media data aren't similar. You can have one analyst examine satellite pictures and another look at social media posts to see if they align, but the process is time-consuming and generally far from comprehensive. The study's authors developed a method for fusing different types of data in a machine-readable way to offer a much clearer picture.

“In light of their ubiquitous emergence, social media increasingly promise to be of great value even though associated applications have thus far remained simple, and their fusion with other data has been largely ad hoc,” the team from North Carolina State University writes in “Fusing Heterogeneous Data: A Case for Remote Sensing and Social Media.” Only by creating a new statistical method for fusing the outputs of satellite data and social media data do you get something you can use to predict what might happen next within a given area of interest, such as a specific nation's nuclear enrichment or weapons development.

The researchers looked at satellite and social media data from August 2013, when deadly floods killed eight people and caused widespread damage in Colorado. They sought to show that if you could algorithmically identify which imagery showed the flooding from space, and which geotagged tweets described it on the ground, you could could much more quickly verify one data set against another — that is, you could determine whether incoming social media data supports the conclusions you might be reaching from your satellite data, and vice versa.

“Next steps for the project include evaluating nuclear facilities in the West to identify common characteristics that may also be applicable to facilities in more isolated societies, such as North Korea,” notes a press release on the paper.

One of the authors, NCSU computer and electrical engineering professor Hamid Krim, said the team would try to “address the insufficient knowledge in general in areas of great interest (e.g. N. Korea and Iran). The goal is to come up with systematic methodologies to transport knowledge about nuclear environments available in other areas (e.g., in the West) to these domains where there is very little available. Creating such an environment in these places of interest will help them detect potential undesired activity.”

Of course, there are limitations to media monitoring in Iran and North Korea. The former's social media environment is largely underground, thanks to bans on Twitter and many other social networks. The latter has virtually no social media environment at all. Krim noted that the “adversarial strategy” of social-media censorship makes his team's analysis harder. But even social posts from nearby countries can help illuminate their more secretive neighbors, he said — think tweets from Japan after earth tremors are felt.

    Boeing Australia collaborates on AI research for unmanned systems

    BRISBANE, Australia, Sept. 25, 2019 — Boeing [NYSE:BA] is partnering with Australia's Trusted Autonomous Systems Defence Cooperative Research Centre (DCRC) to develop advanced artificial intelligence (AI) technologies to create smarter unmanned systems for global forces. Embedding machine learning techniques on-board will help unmanned systems better understand and react to threat environments. “Over the next 12 months, Boeing Australia will design and test cognitive AI algorithms to enable sensing under anti-access conditions and to navigate and conduct enhanced tactics in denied environments,” said Dr. Shane Arnott, director of Phantom Works International. Boeing Australia's first innovation project with the DCRC will examine an unmanned system's route planning, location, and identification of objects and the platform's subsequent behavioural response. The DCRC for Trusted Autonomous Systems was announced by the Australian Government in 2017 to support the rapid creation and transition of industry-led trustworthy smart-machine technologies through the innovation ecosystem to the Australian Defence Force. “Together with Boeing, we are investing in advanced technology that can have real game-changing product outcomes for our military to match the evolving threats and achieve a sustainable autonomous industry for Australia,” said Professor Jason Scholz, chief executive officer of the DCRC for Trusted Autonomous Systems. Boeing will work with Australian university partners and Brisbane-based supplier RF Designs to flight-test and evaluate the capability with autonomous high performance jets. * The Trusted Autonomous Systems DCRC receives funding support from the Australian Government's Next Generation Technologies Fund and the Queensland Government's Advance Queensland initiative. # # # Contact: Melanie de Git Boeing Australia Mobile: +61 423 829 505 melanie.degit@boeing.com Trusted Autonomous Systems DCRC Phone: +61 7 3371 0524 info@tasdcrc.com.au View source version on Boeing : https://boeing.mediaroom.com/2019-09-24-Boeing-Australia-collaborates-on-AI-research-for-unmanned-systems#assets_20295_130508-117

    Our nation’s defense supply chain imperative

    By: Bill Brown, L3Harris Technologies The Department of Defense and defense industry have a long history of responding quickly and forcefully to crisis, and the COVID-19 pandemic is no exception. Today, hundreds of thousands of dedicated defense workers remain at their posts – delivering mission-critical products and services to support our troops around the world, while also providing personal protective equipment and other supplies to first responders and health care workers here at home. However, this most recent crisis has re-exposed weaknesses in our defense industrial base – highlighting the need to significantly bolster the nation's vital supply chain. This serves as a call to action to develop a strategic, long-term approach across government and industry. We witnessed the fallout from the 2008-09 financial crisis. Thousands of suppliers shuttered or permanently shifted precious capacity to other verticals when defense budgets were indiscriminately cut following the Budget Control Act of 2011 and sequester of 2013. When budgets began to recover several years later, the damage was clear – longer lead times that in some cases doubled or more, and increased reliance on single-source and international suppliers for critical components, such as microelectronics. In 2017, President Trump signed an executive order and established a multi-agency task force to study supply chain resiliency. The task force identified five macro forces that create risk to the supply chain and national security preparedness including sequestration and the uncertainty of government spending, the overall decline of U.S. manufacturing capabilities and capacity, harmful government business and procurement practices, industrial policies of competitor nations, and diminishing U.S. STEM and trade skills. Task force members proposed a comprehensive set of risk-reduction actions – ranging from establishing sustained and predictable multi-year budgets and developing an adaptive acquisition framework, to directing investment to small businesses and diversifying the supplier base. Over the past two years, the government has made initial strides on a number of these fronts, including working to reduce U.S. reliance on foreign sources for critical rare earth minerals and decreasing the country's dependence on China and other international suppliers for semiconductors and related components. Unfortunately, the COVID-19 pandemic emerged before these and other task force initiatives gained serious traction and forced the DoD to refocus its near-term priorities. And the urgency escalated when we began to see the brutal impact the pandemic was causing in the commercial aerospace sector, an important vertical market for many defense suppliers. The department quickly designated defense suppliers as essential and increased progress payments, spurring larger defense contractors to accelerate payments to thousands of small business suppliers. These actions helped companies to continue operating, maintain their employment and hiring goals, and sustain critical spending on internal research and development (IRAD) to keep the innovation engine humming. At L3Harris, for example, we recommitted to investing nearly 4 percent of revenues in IRAD, hiring 6,000 new employees and maintaining our apprenticeship and internship programs to provide opportunities for the workforce of the future. The combined DoD and industry efforts demonstrate the power of a focused, collaborative approach to mitigate and address the damaging effects of the pandemic and to support the broader defense industrial base. Today, we are at a critical juncture. We have an opportunity to make the necessary strategic investments that could significantly strengthen our supply base for generations to come, including: · Ensure sustained/predictable budgets – stable, long-term funding helps companies better plan and encourages them to invest in staffing, technology and facilities needed for the country to maintain its technical superiority. Now is not the time to pull back the reins on defense spending. · Accelerate contract awards – shorter decision and acquisition cycles enable suppliers to invest in and deliver technologies faster than with traditional methods, and in the near term could help offset the impact of the commercial aerospace downturn. · Expand domestic supplier base – increasing domestic capabilities reduces vulnerabilities and increases access to critical components, such as rare earths and microelectronics, and over time can help reduce the proportion of sole/single-source supply. · Increase workforce investment – providing advanced STEM education opportunities drives innovation and productivity by enhancing critical skillsets for existing employees, while attracting, training and growing the workforce of the future. · Institutionalize process improvements – the COVID-19 pandemic forced government and industry to find new and more efficient ways to work. The challenge now – to make these advances permanent. These are not quick fixes. However, they provide a strong platform for a more resilient national defense supplier base, which is vital at a time when near-peer adversaries continue to invest heavily in new technologies that threaten our nation's security. The imperative is clear – and the opportunity is now.
