There’s no question that computers don’t understand sarcasm—or didn’t, until some researchers at the University of Central Florida starting them on a path to learning it.

Software engineers have been working on various flavors of sentiment analysis for quite some time. Back in 2005, I wrote an article in Spectrum about call centers automatically scanning conversations for anger—either by the caller or the service operator—one of the early use-cases behind messages like “This call may be monitored for quality assurance purposes.” Since then, software has been getting better and batter at detecting joy, fear, sadness, and confidence, and now, finally, sarcasm.

My guest today, Ramya Akula, is a Ph.D. student and a Graduate Research Assistant at the University of Central Florida's Complex Adaptive Systems Laboratory.

Stopping Infection Outbreaks with AI and Big Data 21:14

Hospitals are where we go to get cured of infections and diseases, but sadly, sometimes tragically, and ironically, they are also places we go to get them. According to the Centers for Disease Control, “On any given day, about one in 31 hospital patients has at least one healthcare-associated infection.” Yet, according to Dr Lee Harrison, “The current method used by hospitals to find and stop infectious disease transmission among patients is antiquated. These practices haven’t changed significantly in over a century.” Until perhaps now. Doctors at the University of Pittsburgh and the University of Pittsburgh Medical Center have developed a new method that uses three distinct, relatively new, technologies, whole-genome sequencing surveillance, and machine learning, and electronic health records to identify undetected outbreaks and their transmission routes. Dr Lee Harrison is a Professor at the University of Pittsburgh, where he’s the Associate Chief of Epidemiology and Education and, more to our point today, the head of its Infectious Diseases Epidemiology Research Unit. He’s the corresponding author of a new paper that describes the new methodology and he’s my guest today. Fixing the Future is the weekly podcast of @IEEE Spectrum and is sponsored by @COMSOL…

A Small Startup Fights Rare Diseases With Big Data 20:51

לפני 4 years20:51

20:51

Rare diseases are, well, rare. In two not unrelated ways. By definition, they’re diseases that afflict fewer than 200,000 people. But because, in the world of big business, in particular big pharma, that’s not enough to bother with, that is, it’s not profitable enough to bother with, rare diseases are rarely worked, to say nothing of cured. For example, hypertryptophanemia is a rare condition that likely occurs due to abnormalities in the body's ability to process the amino acid, tryptophan. How rare? I don’t know. A Google search didn’t yield an answer to that question. In fact, it’s rare enough that Google didn’t even autocomplete the word even with 15 of its 19 letters typed in. Paradoxically, big data has the potential to change that. Because 200,000 is, after all, a lot of data points. But it presents problems of its own. There isn’t one giant pool of 200,000 data points. So the first challenge is to aggregate all the potential data that’s out there. And the big challenge there is that a lot of the data is contained, not in beautifully homogeneous, joinable, relatable databases. It’s buried deep in documents like PubMed articles and patent filings. Deep Learning can help researchers pull that data out of those documents. At least, that’s the strategy of a startup called Vyasa . Here to explain it is Vyasa’s CEO and founder, Christopher Bouton.…

Like a lot of people, you may be thinking about trading in your car. Me too. The case, morally and even financially, for an all-electric car is becoming stronger and stronger. And yet, what about recharging? What’s it like going from, say Pittsburgh to New York’s Hudson Valley—a trip that doesn’t even have a solid cellular connection? What about a road trip my partner to Yosemite and back? And even locally, how do you charge up if you live in a townhouse or apartment? Without a driveway and a garage, can you set up charging at home? Will we have a universal standard for charging? What exactly is fast charging?

IBM’s Fall From World Dominance 25:55

IBM is a remarkable company, known for many things—the tabulating machines that calculated the 1890 U.S. Census, the mainframe computer, legitimizing the person computer, and developing the software that beat the best in the world at chess and then Jeopardy. The company is, though, even more remarkable for the businesses it departed—often while they were still highly profitable—and pivoting to new ones before their profitability was obvious or assured. The pivot that people are most familiar with is the one into the PC market in the 1980s and then out of it in the 2000s. In fact, August 2020 marks the 40th anniversary of the introduction of the IBM PC. Joining me to talk about it—and IBM’s other pivots, past and future—is a person uniquely qualified to do so. James Cortada is both a Ph.D. historian and a 38-year veteran of IBM. He’s currently a senior research fellow at the University of Minnesota’s Charles Babbage Institute , where he specializes in the history of technology.

The most honest and inadvertently funny marketing message I ever saw was at a gas station that was closed for remodeling; it had been an Amaco station before that company was bought by BP . The sign said, “Rebranding, to serve you better.” I’m afraid we’re a bit guilty of that here at Spectrum . This is the 30th episode of IEEE Spectrum’s relaunched podcast series, but the first under a new name, “Fixing the Future.” We’ve changed the name partly for marketing and searchability reasons. But it also signals our intention to focus more intently on ways that technology is being deployed to improve our lives, specifically in three—to be sure overlapping—areas: climate change; machine learning and other smart technologies; and the effects of automation on the nature of work and the future of jobs. I’m hard-pressed to imagine a more on-point guest to help me usher in this change than Myriam Sbeiti.

Until We Get Rid of Fossil Fuels, Can Data Make Them More Efficient? 19:44

לפני 4 years19:44

A few months ago, we had on the show an economist who specialized in the energy sector. She noted that while the Trump administration had put drilling rights the Alaska Natural Wildlife Refuge, or ANWAR, on the block, there wasn’t much interest from the oil industry, and, more generally, the Arctic and other cold climes, presented logistical—and therefore financial—problems for oil companies. To be sure, oil companies have been drilling in the frigid North Sea for decades, but that doesn’t mean it’s been easy. For example, at BP’s Valhall oil field in the Norwegian sector of the North Sea, drilling began in 1982, and the company is still pulling 8000 barrels per day, but losses are considerable—or have been until BP began working with a data science company. Yes, a data science company. Further out, in the middle of the North Sea, another set of BP oil fields, known as Alvheim, has been rediscovered to have greater reserves than previously thought. There, the same data science company optimized a calibration process and in so doing reduced production losses and saved BP considerable money. The data science company’s work isn’t limited to oil and gas. For example, it recently won a research contract with the California Energy Commission to use modeling and data analytics to help it improve production efficiencies in wind energy. The data science company is called Cognite , and my guest today is its Senior Director in charge of Energy Industry Transformation, Carolina Torres.…

Can a Robot Be Arrested? Hold a Patent? Pay Income Taxes? 31:44

When horses were replaced by engines, for work and transportation, we didn’t need to rethink our legal frameworks. So when a fixed-in-place factory machine is replaced by a free-standing AI robot, or when human truck driver is replaced by autonomous driving software, do we really need to make any fundamental changes to the law? My guest today seems to think so. Or perhaps more accurately, he thinks that surprisingly, we do not; he says we need to change the laws less than we think. In case after case, he says, we just need to treat the robot more or less the same way we treat a person. A year ago, he was giving presentations in which he argued that Ais can be patentholders. Since then, his views have advanced even further. And so last summer, Cambridge University Press published a short but powerful treatise, The Reasonable Robot: Artificial Intelligence and the Law . In it, he argues that the law more often than not should not discriminate between AI and human behavior.

The Future of Post-Industrial Cities 33:07

As we begin to finally address climate change in a serious way, we need to look at our cities in a serious way. And not just first-tier cities like, well, New York, San Francisco, Seattle, and Los Angeles, and not just flashy growing cities like Las Vegas, Austin, Atlanta, and Columbus. We need to look at cities like Baltimore, Cleveland, Detroit, Philadelphia, Pittsburgh, St Louis—cities that haven’t come back from the problems—deindustrialization, disinvestment, white flight—of 50 and 60 years ago. These cities are at a crossroads, according to my guest today. They can, he says, enjoy a comeback, stagnate, or continue to decline. There is, in fact, a unique opportunity presented by the pandemic: as working remotely becomes more widely accepted, there could be a migration to cities such as these by people not ready to give up on city life, but looking for greater affordability.

Are Fossil Fuels Impoverishing Middle America? 31:59

I suppose it’s elitist and maybe even nationalistic of me but I was surprised to hear the phrase “resource curse,” which I associate with the developing world, used recently in a webinar in the context of a region of the United States. The region is northern Appalachia, comprising 22 counties in eastern Ohio, western Pennsylvania, and northern West Virginia. And the curse is, as it so often is in the third world, a surfeit of oil and especially natural gas, in this case extractable largely through the relatively new process of fracking. Here to explain how the resource curse is impoverishing communities in the middle of the U.S. in the middle of the 21st century is Sean O’Leary. He’s a senior researcher at the Ohio River Valley Institute and the author of its recent report, “ Appalachia’s Natural Gas Counties: How dreams of jobs and prosperity turned into almost nothing .”…

Self-Walking Exoskeletons 24:45

In the world of prosthetics, we’re still at the stage where a person has to instruct the prosthetic to first do one thing, then another, then another. As University of Waterloo Ph.D. researcher Brokoslaw Laschowski puts it, “Every time you want to perform a new locomotor activity, you have to stop, take out your smartphone and select the desired mode.” But Laschowski and his fellow researchers have been developing a device that uses wearable cameras and deep learning to figure out the task that the exoskeleton-wearing person is engaged in, perhaps walking down a flight of stairs, or along a street, and gets them there, a bit like programming a destination in a self-driving car.

A Theory of (Almost) Everything 39:09

If there’s one thing we can all agree on, it’s that the world is not only changing quickly, it’s changing at a faster rate than ever. Or does it just seem that way? Surely we can all agree that the Industrial Revolution has changed everything. Or has it? One noted economist says there in fact were three industrial revolutions, and only one of them—the second one, from about 1870 to 1914, was important. In fact he largely discounts what we call the information revolution as insubstantial. If you wanted to study the great trends and transitions of civilization—not just Western Civilization, but all of it—and break it down into epochs, and choose from the various transitions the five or seven most significant ones, and study the interplays of these transitions—which are causes of the others, and to what degree, and why some occur quickly and others—like the electric car—are postponed for a hundred years; if you wanted to do all that, it would take a lifetime of study. In fact, you’d have to write ten or thirty books each one of which looks at some aspect of our world from a height of 30,000 feet, and then write an eleventh or thirty-first book that was the encapsulation of all that wisdom. That certainly seems impossible. The last true Renaissance person, someone who knew pretty much all that was known at the time, might have been Aristotle, with asterisks for Franklin and Diderot, and maybe Bertrand Russell. And yet, my guest today—who doesn’t know all that is currently known, but knows quite a bit about almost everything about technology, and the social and cultural changes that technologies have wrought, and what causes technological change itself, has done just that. Václav Smil is a Czech-born Distinguished Professor Emeritus in the Faculty of Environment at the University of Manitoba, a part of the world we don’t always associate with the Renaissance. He’s the author of more than 40 books in an enormously wide range of fields that includes energy and food production, environmental and population change, risk and public policy, and the history of technology and innovation. He’s also a contributing editor at IEEE Spectrum. His new book, which in some sense encapsulates all his prior scholarship, is Grand Transitions: How the Modern World Was Made , published March 1st by Oxford University Press.…

Is Cyberwar War? 24:30

At a conference of chief technology officers in 2016, General Michael Hayden , former head of, at different times, both the NSA and the CIA, told the audience, “Cyberwar isn’t exactly war, but it’s not not-war, either.” Cyberattacks, at the nation-state level, were already almost a decade old at that point. In 2007, over the course of 22 days a Russian attack on Estonia took out commercial and government servers, online banking, and the Domain Name System,” without which people can’t find or look up websites and online servers. The attack carried into the cyber realm an already heated political conflict between the two nations, and Estonia’s economy was as much under attack as its information infrastructure. In 2010, we learned of the U.S.–Israeli attack on Iran and its uranium centrifuges, known as Stuxnet . In 2015, a concerted attack , believed to have been Russian, on the power grid of another east European nation, Ukraine, left more than 200,000 people without electricity for at least several hours. It was the first attack on a grid, and perhaps the first large-scale SCADA attack—that is, on the control systems of critical infrastructure. Follow-up attacks struck the railway, television, and mining sectors. In 2016, right around the time General Hayden was warning American audiences of the dangers of cyberwar, Russia, in conjunction with a private firm, Cambridge Analytica, and elements of the U.S. Republican party, crafted a disinformation campaign to influence the presidential election that year. Russia and Cambridge Analytica also undermined the Brexit referendum in the U.K. earlier that year. Since then, we’ve seen entire families of malware appear, such as Trickbot. Arguably even worse was the recent SolarWinds hack, which in effect was an attack on what we might call the software supply chain. As many as 18 000 different organizations using SolarWinds may have been affected. Worse, the effects of the hack may have been reached out into other networks and therefore been exponential. For example, both Microsoft and security firm FireEye were affected, and they each have many enterprise customers. As the fourth-century Roman poet Juvenal asked, Quis custodiet ipsos custodes? Who shall guard the guardians themselves? A @RadioSpectrum1 conversation with Justin Cappos who heads the Secure Systems Laboratory at @NYU.
