The AI world is booming in a range of metrics covering research, education, and technical achievements, according to AI Index report -- an annual rundown of machine learning data points now in its third year. From a news writeup, which outlines some of the more interesting and pertinent points: AI research is rocketing. Between 1998 and 2018, there's been a 300 percent increase in the publication of peer-reviewed papers on AI. Attendance at conferences has also surged; the biggest, NeurIPS, is expecting 13,500 attendees this year, up 800 percent from 2012.
AI education is equally popular. Enrollment in machine learning courses in universities and online continues to rise. Numbers are hard to summarize, but one good indicator is that AI is now the most popular specialization for computer science graduates in North America. Over 21 percent of CS PhDs choose to specialize in AI, which is more than double the second-most popular discipline: security / information assurance.
The US is still the global leader in AI by most metrics. Although China publishes more AI papers than any other nation, work produced in the US has a greater impact, with US authors cited 40 percent more than the global average. The US also puts the most money into private AI investment (a shade under $12 billion compared to China in second place globally with $6.8 billion) and files many more AI patents than any other country (with three times more than the number two nation, Japan).
AI algorithms are becoming faster and cheaper to train. Research means nothing unless it's accessible, so this data point is particularly welcome. The AI Index team noted that the time needed to train a machine vision algorithm on a popular dataset (ImageNet) fell from around three hours in October 2017 to just 88 seconds in July 2019. Costs also fell, from thousands of dollars to double-digit figures.
Self-driving cars received more private investment than any AI field. Just under 10 percent of global private investment went into autonomous vehicles, around $7.7 billion. That was followed by medical research and facial recognition (both attracting $4.7 billion), while the fastest-growing industrial AI fields were less flashy: robot process automation ($1 billion investment in 2018) and supply chain management (over $500 million).

Magic Leap just announced that they're in the midst of closing a Series E round of funding, but it sounds like they're going to have to clinch that investment with some pretty troubling sales numbers for their only device on the market. From a report: The Information is reporting [paywalled] that Magic Leap managed to sell just 6,000 units of its $2,300 Magic Leap One headset in its first six months on sale, a figure made worse by CEO Rony Abovitz's internal claims that he wanted the startup to sell at least one million units of the device in the first year, a goal the report states he was later convinced to rethink -- Abovitz later projected the company would sell 100,000 units in the first year. The report adds that Magic Leap's second-generation VR headset is "years away from launch" and the startup recently laid off dozens of employees. Magic Leaps counts Google, VC firm Andreessen Horowitz, Alibaba, Qualcomm, AT&T, Japan's NTT Docomo, and the government of Saudi Arabia among its investors.

Japan's economy and industry ministry said Monday that it will start removing melted fuel from the Fukushima Daiichi nuclear power plant in 2021. The milestone step of debris removal is considered the most difficult part of cleaning up the crisis-hit facility. ABC News reports: Nearly nine years after [the Fukushima nuclear power plant was wrecked by a massive earthquake and tsunami], the decommissioning of the plant, where three reactors melted, remains largely an uncertainty. The revised road map, to be formally approved later this month, lacks details on how the complex should look at the end but maintains a 30- to 40-year target to finish.

By far the toughest challenge is to remove the 800 tons of nuclear fuel in the three reactors that melted, fell from the cores and hardened at the bottom of their primary containment vessels. In the past two years, plant operator Tokyo Electric Power Co. (TEPCO), has made progress in gathering details mainly from two of the three reactors. In February, a small telescopic robot sent inside Unit 2 showed that small pieces of debris can come off and be lifted out. The milestone step of debris removal is scheduled to begin at Unit 2 by the end of 2021. [...] TEPCO started removing the fuel rods from the Unit 3 pool in April 2019 and aims to get all 566 removed by March 2021. Removal of the rods from Units 1 and 2 is to begin in 2023. By 2031, TEPCO also plans to remove thousands at two other units that survived the tsunami to be stored in dry casks on the compound. More than 6,300 fuel rods were in six reactor cooling pools at the time of the accident, and only the Unit 4 pool has been emptied. "Japan has yet to develop a plan to dispose of the highly radioactive waste that will come out of the reactors," the report adds. "Under the road map, the government and TEPCO will compile a plan sometime after the first decade of debris removal ending in 2031."

"Experts say a 30- to 40-year completion target for the decommissioning is too optimistic. Some have raised doubts if removing all of the melted fuel is doable and suggest an approach like Chernobyl -- contain the reactors and wait until radioactivity naturally decreases."

An anonymous reader quotes a report from NPR: Greenhouse gas emissions have risen steadily for the past decade despite the current and future threat posed by climate change, according to a new United Nations report. The annual report compares how clean the world's economies are to how clean they need to be to avoid the most catastrophic effects of climate change -- a disparity known as the "emissions gap." However, this year's report describes more of a chasm than a gap. Global emissions of carbon dioxide, methane and other greenhouse gases have continued to steadily increase over the past decade. In 2018, the report notes that global fossil fuel CO2 emissions from electricity generation and industry grew by 2%.

"There is no sign of [greenhouse gas] emissions peaking in the next few years," the authors write. Every year that emissions continue to increase "means that deeper and faster cuts will be required" to keep Earth from warming more than 1.5 to 2 degrees Celsius above preindustrial levels. [...] The United States is currently not on track to meet its greenhouse gas reduction commitments under the Paris Agreement, which the United States ratified and is technically still part of until its withdrawal takes effect in November 2020. According to the new report, six other major economies are also lagging behind their commitments, including Canada, Japan, Australia, Brazil, the Republic of Korea and South Africa. What's interesting is that China's per capita emissions are now "in the same range" as the European Union, thanks to the country's large investments in renewable energy such as solar and wind.

Some of the recommendations for how the world's top economies could cut emissions include: banning new coal-fired power plants, requiring all new vehicles to be CO2-free by 2030, expanding mass transit and/or requiring all new buildings to be entirely electric.

An anonymous reader writes: "HELLO, I'm Scout. Want to play?" My daughter has a toy dog that yaps and comes out with a few stock phrases. When it gets too annoying, I don't hesitate to turn it off. I sometimes think about "losing" Scout, or even "accidentally" breaking it, acts that would be cruel to my daughter but not to the dog. But for how much longer will this be true? Technology is getting better all the time. What will it mean if we can create a robot that is considered alive? If I find myself annoyed by such a robot, would it be wrong to turn it off? Would that be the same as killing it? The answer isn't obvious. Many people already regard robots more sensitively than I do. At Kofukuji temple near Tokyo, Japan, Buddhist priests conduct services for "dead" Aibo robot dogs. In Japan, inanimate objects are considered to have a spirit or soul, so it makes sense for Aibos to be commemorated in this way. Such sentiments aren't confined to Japan, however. Julie Carpenter, a roboticist in San Francisco has written about bomb disposal soldiers who form strong attachments to their robots, naming them and even sleeping curled up next to them in their Humvees. "I know soldiers have written to military robot manufacturers requesting they fix and return the same robot because it's part of their team," she says.

"Guests coming to Asahi Ryokan have the option to pay just ¥100 (about $1) per night to stay the night -- if they agree to have their entire stay livestreamed," reports CNN: [T]here are restrictions around how the livestreaming works. [27-year-old manager] Tetsuya Inoue explains to CNN Travel that the feed is video-only, so guests will have privacy in their conversations or phone calls...

Guests are permitted to turn the lights off, and the bathroom area is out of camera range.

"This is a very old ryokan [traditional Japanese hotel] and I was looking into a new business model," says Inoue, who started running the hotel last year. "Our hotel is on the cheaper side, so we need some added value, something special that everyone will talk about." So far, four guests have taken him up on the offer since Inoue began offering the deal last month.

"Young people nowadays don't care much about the privacy," Inoue adds. "Some of them say it's OK to be [watched] for just one day."
Inoue ultimately hopes to monetize the YouTube channel, according to CNN . (Though it currently appears to be down.)

But Inoue told CNN that when the hotel room is vacant, he plans to just livestream himself, working in his office.

Twitter said it will start letting all users hide replies to the tweets they send, an effort to improve the health of discussions and interactions on the service. From a report: The company has been testing the feature since summer in different markets, including the U.S. and Japan, but is now rolling it out globally. The tool lets users hide specific comments made on their posts, meaning those comments won't be visible to other users unless they click a button to reveal them. The change provides a degree of control that could be used to keep spammers away, or to hide hateful or inappropriate replies.

Manufacturers can prevent the Department of Defense from repairing certain equipment, which puts members of the military at risk. Elle Ekman, a logistics officer in the United States Marine Corps, writes: In the United States, conversations about right-to-repair issues are increasing, especially at federal agencies and within certain industries. In July, the Federal Trade Commission hosted a workshop to address "the issues that arise when a manufacturer restricts or makes it impossible for a consumer or an independent repair shop to make product repairs." It has long been considered a problem with the automotive industry, electronics and farming equipment. Senators Elizabeth Warren and Bernie Sanders have even brought it up during their presidential campaigns, siding with farmers who want to repair their own equipment; while the senators are advocating national laws, at least 20 states have considered their own right-to-repair legislation this year.

I first heard about the term from a fellow Marine interested in problems with monopoly power and technology. A few past experiences then snapped into focus. Besides the broken generator in South Korea, I remembered working at a maintenance unit in Okinawa, Japan, watching as engines were packed up and shipped back to contractors in the United States for repairs because "that's what the contract says." The process took months. With every engine sent back, Marines lost the opportunity to practice the skills they might need one day on the battlefield, where contractor support is inordinately expensive, unreliable or nonexistent. I also recalled how Marines have the ability to manufacture parts using water-jets, lathes and milling machines (as well as newer 3-D printers), but that these tools often sit idle in maintenance bays alongside broken-down military equipment. Although parts from the manufacturer aren't available to repair the equipment, we aren't allowed to make the parts ourselves "due to specifications."

Microsoft has added more than 50 new games to the preview of its Project xCloud game streaming service, including Devil May Cry 5, Tekken 7 and Madden 2020. Engadget reports: In a blog post today, Microsoft said it'll send out a new wave of xCloud preview invites to gamers in the US, UK and South Korea. Starting next year, it also plans to expand the preview to Canada, India, Japan and Western Europe. If you live in one of those countries, you can sign up for the preview here and hope you get selected.

For now, the xCloud preview is only available for Android phones and tablets, but Microsoft says next year it'll also be headed to Windows PCs and other devices. I'm sure Roku owners would be pleased, but it'd be even more intriguing if Microsoft could eventually bring the xCloud preview to smart TVs and Apple devices. While testers need to use Xbox controllers with the service now, Microsoft also says it'll work with other bluetooth controllers next year, including Sony's Dual Shock 4 and Razer's entries. Yes, you'll soon live in a world where you can play Halo with a PlayStation branded gamepad. Among other tidbits, the xCloud preview will also let gamers stream titles they already own next year, as well those made available through Xbox GamePass for subscribers.

Instagram is making Like counts private for some users everywhere. From a report: Instagram tells TechCrunch the hidden Likes test is expanding to a subset of users globally. Users will have to decide for themselves if something is worth Liking rather than judging by the herd. The change could make users more comfortable sharing what's important to them without the fear of people seeing them receive an embarrassingly small number of likes. Instagram began hiding Likes in April in Canada and then brought the test to Ireland, Italy, Japan, Brazil, Australia and New Zealand in July. Facebook started a similar experiment in Australia in September. Instagram said last week the test would expand to the US, but now it's running everywhere to a small percentage of users in each country.

Earlier this year at Mobile World Congress in Barcelona, Microsoft announced the second generation of its HoloLens augmented reality visor. Today, the $3,500 HoloLens 2 is going on sale in the United States, Japan, China, Germany, Canada, United Kingdom, Ireland, France, Australia and New Zealand, the same countries where it was previously available for pre-order. From a report: Ahead of the launch, I got to spend some time with the latest model, after a brief demo in Barcelona earlier this year. Users will immediately notice the larger field of view, which still doesn't cover your full field of view, but offers a far better experience compared to the first version (where you often felt like you were looking at the virtual objects through a stamp-sized window). The team also greatly enhanced the overall feel of wearing the device. It's not light, at 1.3 pounds, but with the front visor that flips up and the new mounting system that is far more comfortable. In regular use, existing users will also immediately notice the new gestures for opening up the Start menu (this is Windows 10, after all). Instead of a 'bloom' gesture, which often resulted in false positives, you now simply tap on the palm of your hand, where a Microsoft logo now appears when you look at it.

Researchers in Japan and at the University of Michigan said Monday that they have found a way to take over Google Home, Amazon's Alexa or Apple's Siri devices from hundreds of feet away by shining laser pointers, and even flashlights, at the devices' microphones. The New York Times reports: In one case, they said, they opened a garage door by shining a laser beam at a voice assistant that was connected to it. They also climbed 140 feet to the top of a bell tower at the University of Michigan and successfully controlled a Google Home device on the fourth floor of an office building 230 feet away. And by focusing their lasers using a telephoto lens, they said, they were able to hijack a voice assistant more than 350 feet away. Opening the garage door was easy, the researchers said. With the light commands, the researchers could have hijacked any digital smart systems attached to the voice-controlled assistants.

They said they could have easily switched light switches on and off, made online purchases or opened a front door protected by a smart lock. They even could have remotely unlocked or started a car that was connected to the device. The researchers, who studied the light flaw for seven months, said they had discovered that the microphones in the devices would respond to light as if it were sound. Inside each microphone is a small plate called a diaphragm that moves when sound hits it. That movement can be replicated by focusing a laser or a flashlight at the diaphragm, which converts it into electric signals, they said. The rest of the system then responds the way it would to sound. While the researchers said they had notified several companies to the light vulnerability, most microphones would need to be redesigned to remedy the problem. And simply covering the microphone with a piece of tape wouldn't solve it.

The findings of the vulnerability can be found here.

MS Power User reports on the results of a 2,300-employee experiment by Microsoft with a four-day work week: In August this year, Microsoft Japan ran an experiment where for one month they had a 3 day weekend, taking Friday off. This was paid leave and did not impact the worker's usual vacation allocation.

Some results were predictable. Workers were happier and took 25.4 percent fewer days off during the month. There were also savings from spending less time at work. 23.1 percent less electricity was used and 58.7 percent fewer pages were printed. More importantly from a bottom-line standpoint, however, productivity went up 39.9%, as fewer and shorter meetings were held, often virtually rather than in person.

A team of researchers from Japan has found compelling evidence of two fisheries collapsing due to use of neonicotinoid pesticides by nearby rice farmers. "In their paper published in the journal Science, the team describes their study of fishery water quality data over two decades and what they learned from it," reports Phys.Org. "Olaf Jensen with Rutgers University has published a Perspective piece discussing the work by the team in the same journal issue." From the report: Back in 1993, fishermen working at two fisheries on the lake found that yields had suddenly dropped dramatically. The reason for it was not known but many suspected it was tied to the use of neonicotinoid pesticides by nearby farmers -- a new practice. To find out if that was indeed the case, the researchers gathered data obtained by other teams studying the lake over a period ten years before and after the collapse of the fisheries.

In looking at the results, the researchers found that the year following the first use of neonicotinoid pesticides in the local area, the amount of zooplankton in the lake nosedived. This was followed by a very swift drop in population of the fish that fed on them. More specifically, they found that zooplankton biomass shrank by approximately 83 percent. That year the smelt harvest was just 22 tons, a dramatic drop from an average haul of 240 tons each year. The researchers note that they also studied other factors that might have led to fishery collapse, such as nutrient depletion or changes in oxygen or salt concentrations. They report that they were not able to find any evidence showing that there might have been something other than pesticides killing the food fish ate leaving them to starve.

ARM will keep supplying Huawei with its chip designs at least through the next generation, the company said today. From a report: That's a reversal from earlier this year, when ARM had reportedly notified personnel to halt all dealings with the Chinese company. "ARM can provide support to HiSilicon for the Armv8-A architecture, as well as the next generation of that architecture, following a comprehensive review of both architectures, which have been determined to be of non-U.S. origin," the company told Engadget in a statement. ARM, purchased by Japan's Softbank for $32 billion back in 2016, was forced to halt its business with Huawei after the US effectively forbade US companies from dealing with it. Last month, Huawei was forced to release the Mate 30 Pro without Google Play, Google Maps, YouTube and other key Google services. However, it was able to find alternative suppliers for other components and makes its own Kirin 990 mobile processor for the Mate 30 using ARM's design architecture.

Japanese hotel chain HIS Group has apologized for ignoring warnings that its in-room robots were hackable to allow pervs to remotely view video footage from the devices. The Register reports: The Henn na Hotel is staffed by robots: guests can be checked in by humanoid or dinosaur reception bots before proceeding to their room. Facial recognition tech will let customers into their room and then a bedside robot will assist with other requirements. However several weeks ago a security researcher revealed on Twitter that he had warned HIS Group in July about the bed-bots being easily accessible, noting they sported "unsigned code" allowing a user to tap an NFC tag to the back of robot's head and allow access via the streaming app of their choice.

Having heard nothing, the researcher made the hack public on October 13. The vulnerability allows guests to gain access to cameras and microphones in the robot remotely so they could watch and listen to anyone in the room in the future. The hotel is one of a chain of 10 in Japan which use a variety of robots instead of meat-based staff. So far the reference is only to Tapia robots at one hotel, although it is not clear if the rest of the chain uses different devices. The HIS Group tweeted: "We apologize for any uneasiness caused," according to the Tokyo Reporter. The paper was told that the company had decided the risks of unauthorized access were low, however, the robots have now been updated.

"While Facebook's upcoming cryptocurrency Libra struggles to keep partners on board and regulators happy, an alternative called OpenLibra is here to address some of Libra's potential shortcomings," reports Mashable: Announced at Ethereum Foundation's Devcon 5 conference in Osaka, Japan, OpenLibra is described as an "open platform for financial inclusion," with a telling tagline: "Not run by Facebook." OpenLibra aims to be compatible with Libra in a technical sense, meaning someone building an app on the Libra platform should be able to easily deploy it to OpenLibra as well. OpenLibra's token's value will be pegged to the value of the Libra token.

But while Libra will be a permissioned blockchain (meaning, roughly, that only permitted parties will be able to run a Libra node), OpenLibra will be permissionless from the start. There's an important difference in governance, too. Libra will initially be run by a foundation comprised of up to a 100 corporations and non-profits. It's not entirely clear how OpenLibra will be governed, but the 26-strong "core team" of the project includes people related to cryptocurrency projects such as Ethereum and Cosmos.

JustAnotherOldGuy shares a report from Boing Boing, with the caption: "Enhance, zoom in... more... more... straight out of CSI." From the report: Last month a Japanese entertainer named Ena Matsuoka was attacked in front of her home in Tokyo. Her alleged attacker, an obsessed fan, was able to figure out where she lived by zooming in on a high resolution photo and identifying a bus stop reflected in her pupils. According to Asia One, the alleged attacker "even approximated the storey Matsuoka lived on based on the windows and the angle of the sunlight in her eyes."

"This is a highly charged story," began Olof Ramstrom, a member of the Nobel Committee for Chemistry, announcing that a trio of chemists who spent decades developing the lithium ion battery were today awarded the Nobel Prize in Chemistry for their work. From a report: These batteries, small and powerful compared to older battery technology, made possible pocket-sized mobile phones, laptop computers, electric cars, and renewable energy devices such as solar panels that can help address the problems of climate change, Ramstrom says. The prize will be shared by John B. Goodenough from the University of Texas at Austin, M. Stanley Whittingham from Binghamton University in New York, and Akira Yoshino, who works at Asahi Kasei Corporation and Meijo University in Japan. They will split the roughly $1 million award. Lithium batteries have been touted as Nobel-worthy for years, says Bonnie Charpentier, president of the American Chemical Society. "I think that it's magnificent that Goodenough won this year," she says, noting that at age 97 he is the oldest Nobel laureate. Yoshino is 71, showing that the research stretched across generations.

Indeed, it was in the 1970s that Whittingham began investigating the use of lithium, the smallest and lightest metal in the periodic table of the elements. That size and weight made it possible to pack a lot of lithium into a small space, unlike the large and heavy lead-acid batteries that dominated at the time. Lithium had another advantage: it easily gave up its electrons, and batteries produce electricity when electrons flow from one end, called the anode, to the other end, called the cathode. Whittingham put metallic lithium in one end and a layered material called titanitum disulphide at the other; the titanium had spaces that could capture the flowing electrons. However, this combination of materials also had the unfortunate potential to explode. Slashdot interviewed Goodenough two years ago. You can read the interview here.

The Trump administration has begun inserting legal protections into recent trade agreements that shield online platforms like Facebook, Twitter and YouTube from lawsuits, a move that could help lock in America's tech-friendly regulations around the world even as they are being newly questioned at home. From a report: The protections, which stem from a 1990s law, have already been tucked into the administration's two biggest trade deals -- the United States-Mexico-Canada Agreement and a pact with Japan that President Trump signed on Monday. American negotiators have proposed including the language in other prospective deals, including with the European Union, Britain and members of the World Trade Organization. The administration's push is the latest salvo in a global fight over who sets the rules for the internet. While the rules for trading goods have largely been written -- often by the United States -- the world has far fewer standards for digital products. Countries are rushing into this vacuum, and in most cases writing regulations that are far more restrictive than the tech industry would prefer.

Europe has enacted tough policies to curb the behavior of companies like Facebook and Google and passed laws to deal with privacy, hate speech and disinformation. China has largely cordoned itself off from the rest of the internet, allowing Beijing to censor political content and bolster Chinese tech companies like Alibaba and Tencent. In India, Indonesia, Russia and Vietnam, governments are introducing regulations to ostensibly protect their citizens' privacy and build domestic internet industries that critics say will stymie the ability of American companies to provide services in those countries. The United States wants its more permissive rules to form the basis for worldwide regulation. But there is a rising debate about whether its regime of internet regulations has failed to protect consumer privacy, encouraged the spread of disinformation and supported a powerful forum for harassment and bullying.

The American rules, codified in Section 230 of the Communications Decency Act, shield online platforms from many lawsuits related to user content and protect them from legal challenges stemming from how they moderate content. Those rules are largely credited with fueling Silicon Valley's rapid growth. The language in the trade deals echoes those provisions but contains some differences. That freedom has come under intense criticism from lawmakers and advocates. They say the 23-year-old law has allowed companies like Facebook and Google to avoid responsibility for harm associated with content that reaches billions of users. That anger has been compounded by revelations about the role of Silicon Valley's business practices in the spread of disinformation and treatment of user data.
