The Trouble With China's Edge In The Artificial Intelligence Arms Race – Analysis

#artificialintelligence

China has been making massive investments to create a huge pool of AI experts. The Chinese government wants to overtake the United States and be the global leader in the field by 2030. Artificial Intelligence or AI, simply described as the machine intelligence, has come to apply itself in several different sectors across countries in recent years, including healthcare, finance, education and security. But it has also increasingly become inserted into wider geopolitical conversations about the capabilities of major powers, including the United States and China. Within that aspect of the ongoing conversation, in terms of market share within the industry, the leadersin the field include the United States, with around 40 percent of the global market by some accounts, with countries like China, Israel, Germany, Canada and Russia fast catching up.


China plans new era of sea power with unmanned AI submarines

#artificialintelligence

China is planning to upgrade its naval power with unmanned AI submarines that aim to provide an edge over the fleets of their global counterparts. A report by the South China Post on Sunday revealed Beijing's plans to build the automated subs by the early 2020s in response to unmanned weapons being developed in the US. The subs will be able to patrol areas in the South China Sea and Pacific Ocean that are home to disputed military bases. While the expected cost of the submarines has not been disclosed, they're likely to be cheaper than conventional submarines as they do not require life-supporting apparatus for humans. However, without a human crew, they'll also need to be resilient enough to be at sea without onboard repairs possible.


China military develops robotic submarines that are powered by AI

The Chinese military is developing a fleet of new submarines that will navigate the ocean without a human crew, according to scientists involved in the project. The submarines will be powered by Artificial Intelligence (AI), allowing them to navigate independently and work alongside existing fleets. The crew-less submersibles will be relatively large and low-cost compared to other military watercrafts, according to scientists working on the project. The AI submarines are rumoured to be fitted with diesel-electric engines to enable them to stay at sea for several months without returning to dock. China will use these unmanned subs for intelligence gathering missions, planting sea mines, and'kamikaze'-style attacks on high-value targets, the scientists said.


China developing robotic subs to launch new era of sea power

#artificialintelligence

China is developing large, smart and relatively low-cost unmanned submarines that can roam the world's oceans to perform a wide range of missions, from reconnaissance to mine placement to even suicide attacks against enemy vessels, according to scientists involved in these artificial intelligence (AI) projects. The autonomous robotic submarines are expected to be deployed in the early 2020s. While not intended to entirely replace human-operated submarines, they will challenge the advantageous position established by Western naval powers after the second world war. The robotic subs are aimed particularly at the United States forces in strategic waters like the South China Sea and western Pacific Ocean, the researchers said. The project is part of the government's ambitious plan to boost the country's naval power with AI technology.


China Planning to Deploy Large Unmanned AI Submarines by 2020s

#artificialintelligence

The South China Post reported Sunday that Beijing expects to deploy artificially intelligent unmanned submarines in the early 2020s. The seacraft could be used to survey waters, place munitions or even be used in suicide attacks against enemies, scientists involved in the program told the outlet. Lin Yang, marine technology equipment director at the Shenyang Institute of Automation, Chinese Academy of Sciences, confirmed the program, and said it was a response to work in the US to develop similar watercraft. These subs, dubbed extra-large unmanned underwater vehicles, or XLUUVs, are much bigger than the current crop of underwater vehicles -- large enough to dock as conventional submarines and to carry significant weaponry and other equipment. Their artificial intelligence will help them operate undersea, not only to avoid natural phenomena, but to detect and identify friendly or hostile ships and make navigational decisions to avoid them.


NEC to construct Bay to Bay Express Cable System

ZDNet

NEC has announced being chosen to construct the new 16,000km Bay to Bay Express Cable System (BtoBE), which is being funded by a consortium including Facebook, Amazon Web Services (AWS), and China Mobile International to connect Singapore and Hong Kong with the United States. Pointing to the Guangdong-Hong Kong-Macao Bay and San Francisco Bay areas, NEC said the subsea cable system, consisting of multiple pairs of optical fibre, will be constructed using "the most advanced optical submarine transmission equipment". "The BtoBE, landing at three locations spanning across the Pacific Ocean, is designed so that once completed, it can carry at least 18Tbs of capacity per fibre pair," NEC Corporation general manager of the Submarine Network Division Toru Kawauchi said. BtoBE is slated to be complete by Q4 in 2020, and will cover the longest distance without regeneration, according to NEC. NEC had in May demonstrated artificial intelligence (AI) subsea cable tech which it said could upgrade the spectral efficiency across the FASTER subsea cable system to 6 bits per second per hertz for a capacity of more than 26Tbps -- over two and a half times the capacity originally planned, at no additional wet plant capex.


US Navy reveals plans for radical long range stealth 'supertorpedo'

Daily Mail

The US Navy is planning a major upgrade to its most commonly used torpedo. Military bosses are hoping to build a new'advanced capabilities' version of the submarine launched Mk48 with longer range and improved stealth capabilities. This will boost is ability to destroy enemy ships, submarines and small boats, especially in shallow water, they hope. The new version will be known as the Mk 48 (advanced capability) torpedo, and it is hoped it will feature an array of new technologies including improved sonar, stealth and control systems. Navy weapons developers are looking for a high-tech, longer range and more lethal submarine-launched heavyweight for use in US submarines.


Russia Developing Super-Autonomous Robotic Submarine That Will Not Run On Nuclear Power

International Business Times

Russian scientists are developing an advanced automated submarine that will be powered by an external combustion engine, Igor Denisov, deputy director of the Foundation for Advanced Studies (FPI), revealed in an interview with Interfax, a Russian news agency. "We are planning to create an apparatus that will pass through the Northern Sea Route without floating up and without the use of nuclear power, including under the ice," Denisov said. "In order for this device to accomplish such a'feat,' its autonomy should be at least 90 days, which is already commensurate with the autonomy of modern submarines." The decision to forego the nuclear option to power the underwater vehicle was a conscious one, Denisov said, in order to make it increasingly safe. While a nuclear installation helps power submarines for uninterrupted movement throughout the world's oceans, it also puts its operational capabilities at risk.


NEC demos 26Tbps subsea cable AI tech

ZDNet

NEC has said the spectral efficiency across the FASTER subsea cable system can be upgraded to 6 bits per second per hertz for a capacity of more than 26 terabits per second (Tbps) -- over two and a half times the capacity originally planned at no additional wet plant capex. In joint research with Google, NEC said the tests made use of artificial intelligence (AI) and probabilistic shaping at a 64 Quadrature Amplitude Moderation (64 QAM) modulation. "For the first time on a live cable, artificial intelligence was used to analyse data for the purpose of nonlinearity compensation (NLC). NEC developed an NLC algorithm based on data-driven deep neural networks to accurately and efficiently estimate the signal nonlinearity," NEC said. "In doing so, the authors set a spectral efficiency-distance product record of 66,102b/s/Hz in a field trial performed together with live traffic neighbouring channels."


NEC brings AI to submarine cable networks

#artificialintelligence

Tokyo, Japan and Princeton, NJ, U.S.A., May 15, 2018 - NEC Corporation (NEC; TSE: 6701) announced today successful transmission tests that took place over a commercial subsea cable measuring more than 10,000 kilometers using artificial intelligence (AI) and probabilistic shaping at a modulation of 64QAM. NEC, in a joint research publication with Google, has demonstrated for the first time that the FASTER open subsea cable can be upgraded to a spectral efficiency of 6 bits per second per hertz (b/s/Hz) in an 11,000km segment. This represents a capacity of more than 26 terabits per second (Tb/s) in the C-band, which is over 2½ times the capacity originally planned for the cable, for no additional wet plant capital expenditure. In doing so, the authors set a spectral efficiency-distance product record of 66,102 b/s/Hz in a field trial performed together with live traffic neighboring channels. The team achieved this result using near-Shannon probabilistic-shaping at a modulation of 64QAM, and for the first time on a live cable, artificial intelligence (AI) was used to analyze data for the purpose of nonlinearity compensation (NLC).
