Artificial Intelligence’s ‘Black Box’ Is Nothing to Fear

Vijay Pande in NYT:

Merlin_132848522_5a2fe91c-98c8-4d3b-8a68-bb61fe2673f6-superJumboAlongside the excitement and hype about our growing reliance on artificial intelligence, there’s fear about the way the technology works. A recent MIT Technology Review article titled “The Dark Secret at the Heart of AI” warned: “No one really knows how the most advanced algorithms do what they do. That could be a problem.” Thanks to this uncertainty and lack of accountability, a report by the AI Now Institute recommended that public agencies responsible for criminal justice, health care, welfare and education shouldn’t use such technology. Given these types of concerns, the unseeable space between where data goes in and answers come out is often referred to as a “black box” — seemingly a reference to the hardy (and in fact orange, not black) data recorders mandated on aircraft and often examined after accidents. In the context of A.I., the term more broadly suggests an image of being in the “dark” about how the technology works: We put in and provide the data and models and architectures, and then computers provide us answers while continuing to learn on their own, in a way that’s seemingly impossible — and certainly too complicated — for us to understand. There’s particular concern about this in health care, where A.I. is used to classify which skin lesions are cancerous, to identify very early-stage cancer from blood, to predict heart disease, to determine what compounds in people and animals could extend healthy life spans and more. But these fears about the implications of black box are misplaced. A.I. is no less transparent than the way in which doctors have always worked — and in many cases it represents an improvement, augmenting what hospitals can do for patients and the entire health care system. After all, the black box in A.I. isn’t a new problem due to new tech: Human intelligence itself is — and always has been — a black box.

Let’s take the example of a human doctor making a diagnosis. Afterward, a patient might ask that doctor how she made that diagnosis, and she would probably share some of the data she used to draw her conclusion. But could she really explain how and why she made that decision, what specific data from what studies she drew on, what observations from her training or mentors influenced her, what tacit knowledge she gleaned from her own and her colleagues’ shared experiences and how all of this combined into that precise insight?

The new surveillance capitalism

John Naughton in Prospect:

Screen-Shot-2018-01-19-at-17.34.43The “dust of exploded beliefs,” the English aphorist Geoffrey Madan once wrote, “may make a fine sunset.” We’re beginning to see that glow over the internet which, if you count back to the design phase in the autumn of 1973, is now over four decades old.

From the moment the internet first opened for semi-public use in January 1983, it evoked utopian dreams. It was easy to see why. Cyberspace—the term coined by the novelist William Gibson for the virtual space behind the screen—really did seem to be a parallel universe to “meatspace,” the term invented by Grateful-Dead-lyricist-turned-essayist John Perry Barlow for the messy physical world that we all inhabit. Cyberspace in the 1980s was a glorious sandpit for geeks: a world with no corporations, no crime, no spam, no hate speech, relatively civil discourse, no editorial gatekeepers, no regulation and no role for those meatspace masters whom Barlow called the “weary giants of flesh and steel.”

But then, gradually, the internet was commercialised and those two parallel spaces merged to create our networked world, in which the affordances of cyberspace combine with surveillance and corporate control. Of course, the internet has brought huge benefits in terms of access to information and efficiency of communication: try imagining our home or work lives without it. But there are serious worries. The online world is populated by several billion mostly passive addicts of devices, apps and services created by a handful of corporate giants. Prying governments and giant companies have acquired the capacity to surveil our every move, both on the internet and, now that so many devices have built-in GPS, in the real world too. Through their ability to monitor our searches these companies—as well as the governments they co-operate with—are able to see our innermost thoughts and desires. (Yes, even our desires: what people search for on Google is incredibly revealing.)

It all creates the potential for unprecedented manipulation, and—rather suddenly—worries are piling up about how that network technology is disrupting our society, warping our children’s development, our politics and our lives. Even the digital evangelists are having second thoughts.

MEET THE AMATEUR SCIENTIST WHO DISCOVERED CLIMATE CHANGE 80 YEARS AGO

Charles C. Mann in Wired:

Mann_Desert_finalTODAY GUY CALLENDAR is a historical footnote, but tomorrow he will have a chapter of his own. Born in 1898, Callendar was the son of Britain’s leading steam engineer, a successful academic and inventor who raised his children in a 22-room mansion. A greenhouse on the grounds was converted into a laboratory for the children until one of Callendar’s three brothers blew it up trying to make TNT. The same brother put out Callendar’s left eye. Undeterred by the subsequent lack of depth perception, he became his father’s successor as the nation’s most important steam engineer.

None of this is why Guy Callendar’s name will be boldfaced in tomorrow’s textbooks. Instead it will be because he was willing to delve into fields he knew nothing about, atmospheric science among them. Nobody knows why he got so interested in the air. Callendar himself attributed it to ordinary curiosity: “As man is now changing the composition of the atmosphere at a rate which must be very exceptional on the geological time-scale, it is natural to seek for the probable effects of such a change.”

In the early 1930s Callendar began collecting measurements of the properties of gases, the structure of the atmosphere, the sunlight at different latitudes, the use of fossil fuels, the action of ocean currents, the temperature and rainfall in weather stations across the world, and a host of other factors. It was a hobby, but a remarkably ambitious one: He was producing the first rough draft of the huge climate models familiar today.

Zadie Smith: ‘I have a very messy and chaotic mind’

Zadie Smith has been a vital literary voice since her first novel, White Teeth, became an instant bestseller. Here she answers questions from famous fans, including Teju Cole, Philip Pullman and Sharmaine Lovegrove.

From The Guardian:

ScreenHunter_2943 Jan. 25 18.11Zadie Smith’s second collection of essays, Feel Free, could be described as a tour through her enthusiasms punctuated with diversions. She writes with equal fervour about Jay-Z’s rapping, which “pours right into your ear like water from a tap”, as about Edward St Aubyn’s “rich, acerbic comedy”. Her early dislike of Joni Mitchell is used as a segue into a discussion of philistinism and taste. A booklet on early Italian masterpieces sparks an examination of the concept of corpses and the unthinkability of death.

Although the subjects may seem wide-ranging, she says, “they always seem very narrow to me. I’m very familiar with what I’m enthusiastic about, and it’s hard to see variety in your own tastes.” The only thing they all have in common is how passionately she feels about them. “I like to know I love something before I pitch it. For me, writing 3,000 words about something you don’t really like is a kind of torture.”

Written between 2008 and 2017, the 33 essays, columns and reviews were, in a way, a respite from her fiction. “Usually an essay comes when I’m playing hookey from novel writing,” she says. “Writing a novel is like doing a long-distance race, and writing an essay in the middle of one is like turning left off the route, finding a cafe and paying close attention to something different. It’s a form of relief.” They are also fundamentally different writing practices. “Fiction is messier. Essay is, for me, an attempt at a kind of clarity. I have a very messy and chaotic mind, but when I’m writing an essay I find I can exert a bit more control over it.”

Thursday Poem(s)

Univited Poem

Rude poem broke into
my conversation with myself,
not making lots of sense,
used inappropriate words,
things out of context,
whined of its lot—
“damned if it did,
damned if it didn’t”—
swapped things for non-things,
hummed some,
talked so long,
repeating much,
rain began falling.
I heard it in the leaves.
I gave up, gave in to listening,
said to myself, That does make sense.

Dulltopia: On the Dystopian Impulses of Slow Cinema

Mark Bould in the Boston Review:

Dulltopia4Fredric Jameson’s essay in An American Utopia (2016) begins with the observation, “We have seen a marked diminution in the production of new utopias over the last decades (along with an overwhelming increase in all manner of conceivable dystopias, most of which look monotonously alike).” Jameson recognizes the profligacy with which capitalism, its eye always on the main chance, belches dystopias. At the same time, he regrets its dulling of human creativity and, thus, its homogenization of dystopia. Yearning for richness, he finds formulaic reiteration. Risk-averse publishers gamble millions on the tried-and-tested strategy of more of the (slightly re-jigged) same. As does Hollywood, albeit on greater orders of magnitude.

Nearly 300 pages further into the same book, Slavoj Žižek insists that the “dystopias that abound in recent blockbuster movies and novels (Elysium, The Hunger Games), although apparently leftist (presenting a postapocalyptic society of extreme class divisions), are unimaginative, monotonous, and also politically wrong.”

Where the Marxist locates monotony in the similarity between dystopias, the Lacanian implies that each individual example is tedious, hackneyed, and wrongheaded. I am not entirely convinced by either one.

Why Did Two-Thirds of These Weird Antelope Suddenly Drop Dead?

Ed Yong in The Atlantic:

Lead_960It took just three weeks for two-thirds of all the world’s saiga to die. It took much longer to work out why.

The saiga is an endearing antelope, whose bulbous nose gives it the comedic air of a Dr. Seuss character. It typically wanders over large tracts of Central Asian grassland, but every spring, tens of thousands of them gather in the same place to give birth. These calving aggregations should be joyous events, but the gathering in May 2015 became something far more sinister when 200,000 saiga just dropped dead. They did so without warning, over a matter of days, in gathering sites spread across 65,000 square miles—an area the size of Florida. Whatever killed them was thorough and merciless: Across a vast area, every last saiga perished.

Richard Kock, a veterinarian and conservationist from the Royal Veterinary College, saw it all. He and his team were there on a routine monitoring trip to check the health of the population. “Mass mortality events are never nice things and I’ve experienced quite a few,” he says. “But the experience of the saiga was unprecedented, and unworldly. Even after 40 years of work, I just said: I don’t understand.”

Does This Man Know More Than Robert Mueller?

Simon van Zuylen-Wood in New York Magazine:

19-greenwald-feature-lede.w512.h600.2xIt’s 10:45 p.m. Rio de Janeiro time. Glenn Greenwald and I are finishing dinner at a deserted bistro in Ipanema. The restaurant, which serves its sweating beer bottles in metal buckets and goes heavy on the protein, is almost aggressively unremarkable (English menus on the table, a bossa-nova version of “Hey Jude” on the stereo). Greenwald avoids both meat and alcohol but seems to enjoy dining here. “I really believe that if I still lived in New York, the vast majority of my friends would be New York and Washington media people and I would kind of be implicitly co-opted.” He eats a panko-crusted shrimp. “It just gives me this huge buffer. You’ve seen how I live, right? When I leave my computer, that world disappears.”

Greenwald, now 50, has seemed to live in his own bubble in Rio for years, since well before he published Edward Snowden’s leaks and broke the domestic-spying story in 2013 — landing himself a Pulitzer Prize, a book deal, and, in time, the backing of a billionaire (that’s Pierre Omidyar) to start a muckraking, shit-stirring media empire (that’s First Look Media, home to the Intercept, though its ambitions have been downgraded over time). But he seems even more on his own since the election, just as the agitated left has regained the momentum it lost in the Obama years.

The reason is Russia. For the better part of two years, Greenwald has resisted the nagging bipartisan suspicion that Trumpworld is in one way or another compromised by a meddling foreign power. If there’s a conspiracy, he suspects, it’s one against the president; where others see collusion, he sees “McCarthyism.” Greenwald is predisposed to righteous posturing and contrarian eye-poking — and reflexively more skeptical of the U.S. intelligence community than of those it tells us to see as “enemies.”

And even if claims about Russian meddling are corroborated by Robert Mueller’s investigation, Greenwald’s not sure it adds up to much — some hacked emails changing hands, none all that damaging in their content, maybe some malevolent Twitter bots.

The Untold Story of the Other Great Black Renaissance

Collectionimage-1Mark Whitaker at The Paris Review:

That story of Pittsburgh is well documented. Far less chronicled but just as extraordinary is the confluence of forces that made the black population of the city, for a brief but glorious stretch of the twentieth century, one of the most vibrant and consequential communities of color in U.S. history. Like millions of other black people, they came north before and during the Great Migration, many of them from the upper parts of the old South, from states such as Maryland, Delaware, Virginia, and North Carolina. As likely as not to have been descendants of house slaves or free men of color, these migrants arrived with high degrees of literacy, musical fluency, and religious discipline—as well as a tendency toward light skin that betrayed their history of mixing with white masters and with one another. Once they settled in Pittsburgh, they had educational opportunities that were rare for black people of the era, thanks to abolitionist-sponsored university scholarships and integrated public high schools with lavish Gilded Age funding. Whether or not they succeeded in finding jobs in Pittsburgh’s steel mills—and often they did not—they inhaled a spirit of commerce that hung, quite literally, in the dark, sulfurous air.

The result was a black version of the story of fifteenth-century Florence and early-twentieth-century Vienna: a miraculous flowering of social and cultural achievement all at once, in one small city. In its heyday, from the twenties until the late fifties, Pittsburgh’s black population was less than a quarter of the size of New York City’s and a third of the size of Chicago’s, those two much-larger metropolises that have been associated with the phenomenon of a black renaissance.

George Schuyler: An Afrofuturist Before His Time

Jacob-lawrence-harlem-streetDanzy Senna at the NYRB:

Black No More argues compellingly, provocatively, that the idea of blackness is necessary in order for whiteness to survive. It is much like James Baldwin famously said: “What white people have to do is try and find out in their own hearts why it was necessary to have a nigger in the first place, because I’m not a nigger. I’m a man, but if you think I’m a nigger, it means you need it.… If I’m not a nigger and you invented him—you, the white people, invented him—then you’ve got to find out why. And the future of the country depends on that, whether or not it’s able to ask that question.”

Schuyler shows all the ways white people are lost without black people to define themselves against. In one late, amazing scene in Black No More, the pastor of a failing white church in the South is grieving the loss of black people after they’ve all turned white. He is grieving the fact that there is nobody left for him to lynch—and without black bodies to lynch, the white parishioners will never know the pastor’s true greatness.

Schuyler dedicated Black No More to “all Caucasians in the great republic who can trace their ancestry back ten generations and confidently assert that there are no Black leaves, twigs, limbs or branches on their family trees.” Before it had been confirmed by social scientists, he understood that there was no such thing as race as a real, biologically determined category.

inmates and wildfires

Wsnpic3-2André Naffis-Sahely at Harper's Magazine:

Two days after the fires in Sylmar burned twenty-nine horses alive at a local ranch owned by the Padilla family, the evacuation orders were starting to be lifted. A rancher rode her horse calmly along Tujunga Canyon Boulevard, ash and dirt clinging to her clothes and arms. I was driving around the LA neighborhoods of Sylmar, Lake View Terrace and Tujunga in the San Fernando Valley, hugging the outer perimeter of the 16,000-acre Creek Fire, one of the eleven fires that tore across Southern California last month. A few minutes after spotting the rancher on her horse, I pulled off the road slightly before a police checkpoint. The officers, slouched against their motorcycles, were only letting residents pass. It was sunset and the air was still visibly thick with smoke. The neighborhood was mostly deserted, but a small trickle of residents could be seen pulling into their driveways. On the side of the road, a few cheerful, handwritten signs had already sprung up. Almost universally, they read: THANK YOU LAPD, FIREFIGHTERS AND FIRST RESPONDERS. It is difficult to estimate exactly how many of Tujunga’s inhabitants knew that their homes hadn’t been saved by firemen, but by ‘angels in orange’, or the thousands of convicts who have kept Californians safe from wildfires since World War II. Not a single sign mentioned them by name.

While Californians may not know them by name, the angels always turn out in force when a fire erupts. On December 6, when some of the blazes in Los Angeles County were at their peak, the official Twitter account for the California Department of Corrections and Rehabilitation (CDCR) tweeted that 1,500 angels were on fire lines in the LA, Ventura and San Bernardino counties, dispatched from as far north as the Bay Area.

Wednesday Poem

Next Stop

May morning. I lie between two dogs, the little
new one rests against my leg, the middle-sized
old one curls into an oval in her bed on the floor.
They’ve been fed. I’ve been coffeed. In-between-time.
I’ve been reading some poems, and though I can

think of nothing they’ve said that would cause this
to happen, I’m sixteen and on a train going off to college.
The engine has failed to keep up with the striding sun so

the sky has fallen dark. An answering dark has risen
from the forest and hills of Penn’s woods.
I’d been
on trains before, mostly the New-Haven Hartford
into New York City even though it was more expensive
than the usual trolley to subway and on down.

Now I’ve eaten
from the heavy silver and thin china of the dining car,
smoked a cigarette in the shifting, noisy space
where the car before links to the car behind.

I have gotten my one sweater out of my suitcase
and folded my sports jacket with the too-short
sleeves so it wouldn’t wrinkle much. I’ve read
all my eyes will allow in the dim coach car light.

Nothing to do but try to sleep while the train
ticked along the rails that would not let it go
other than where it was going, then sleeping,
fitfully, even through the Pittsburgh stopover,

till I woke up, fed the dogs, made coffee
and started to read poems….

This Way Madness Lies

Cesare Lombordo in Lapham’s Quarterly:

Death-of-socrates-HThe conception of the morbid and degenerative character of genius is confirmed and completed more and more when its isolated phenomena are subjected to a more rigorous examination and, as in chemical reactions, to mutual contact. If, in fact, we analyze the lives and works of those great diseased minds that have become famous in history, we find that they can at once be distinguished by many characteristic traits from the average man and also, in part, from other geniuses who have completed their life’s orbit without trace of madness. Genius is conscious of itself, appreciates itself, and certainly has no monkish humility. Sometimes geniuses change their career and course of study several times in succession, as though the mighty intellect could not find rest and relief in a single science. These energetic and terrible intellects are the true pioneers of science; they rush forward regardless of danger, facing with eagerness the greatest difficulties—perhaps because it is these that best satisfy their morbid energy. They seize the strangest connections, the newest and most salient points; and here I may mention that originality, carried to the point of absurdity, is the principal characteristic of insane poets and artists.

The principal trace of the delusions of great minds is found in the very construction of their works and speeches, in their illogical deductions, absurd contradictions, and grotesque and inhuman fantasies. Thus Socrates was clearly of unsound mind when, after having all but arrived intuitively at Christian morality and Judaic monotheism, he directed his steps in accordance with a sneeze, or the voice and signs of his imaginary genius. The temper of these men is so different from that of average people that it gives a special character to the different psychoses (melancholia, monomania, etc.) from which they suffer, so as to constitute a special psychosis, which might be called the psychosis of genius.

Cancer immunotherapy research round-up

Joana Osorio in Nature:

Melanoma: Personal vaccines and virus therapy

NaturePersonalized vaccines and viruses that infect and destroy cancer cells can help the immune system to build up a strong and specific attack against skin cancers. Melanoma cells typically carry many mutations, which results in the production of altered proteins not present in healthy cells. Vaccines against such tumour-specific proteins stimulate the immune system to target and destroy the malignant cells. Patrick Ott at the Dana-Farber Cancer Institute in Boston, Massachusetts, and his colleagues created personalized vaccines that each included 20 altered peptides present in tumours of individuals at high risk of melanoma recurrence. Of six people vaccinated, four remained free of tumours 25 months later. The cancer recurred in the remaining two, but completely regressed after therapy with PD-1 inhibitors — antibodies to the cell-surface protein programmed cell death protein 1 (PD-1) that block the damping down of immune responses and so prevent cancer cells from avoiding destruction.

Ugur Sahin at BioNTech in Mainz, Germany, and his collaborators vaccinated 13 people with RNA molecules encoding up to 10 peptides specific to their individual melanomas. After 12–23 months, 8 individuals were cancer-free. In two other patients, tumours regressed after vaccination, and in one more patient, after vaccination and treatment with a PD-1 inhibitor. Antoni Ribas at the University of California, Los Angeles, and an international team treated 21 patients who had advanced melanoma with injections of an oncolytic virus into the tumour, followed by combined therapy with a PD-1 inhibitor. The virus attracted immune cells to the tumour, and the inhibition of PD-1 boosted immune activity throughout the body. Patients tolerated and responded well to the therapy, with an overall response rate of 62%.

No Longer Writing, Philip Roth Still Has Plenty to Say

Charles McGrath in the New York Times:

21McGrath-superJumboWith the death of Richard Wilbur in October, Philip Roth became the longest-serving member in the literature department of the American Academy of Arts and Letters, that august Hall of Fame on Audubon Terrace in northern Manhattan, which is to the arts what Cooperstown is to baseball. He’s been a member so long he can recall when the academy included now all-but-forgotten figures like Malcolm Cowley and Glenway Wescott — white-haired luminaries from another era. Just recently Roth joined William Faulkner, Henry James and Jack London as one of very few Americans to be included in the French Pleiades editions (the model for our own Library of America), and the Italian publisher Mondadori is also bringing out his work in its Meridiani series of classic authors. All this late-life eminence — which also includes the Spanish Prince of Asturias Award in 2012 and being named a commander in the Légion d’Honneur of France in 2013 — seems both to gratify and to amuse him. “Just look at this,” he said to me last month, holding up the ornately bound Mondadori volume, as thick as a Bible and comprising titles like “Lamento di Portnoy” and “Zuckerman Scatenato.” “Who reads books like this?”

In 2012, as he approached 80, Roth famously announced that he had retired from writing. (He actually stopped two years earlier.) In the years since, he has spent a certain amount of time setting the record straight. He wrote a lengthy and impassioned letter to Wikipedia, for example, challenging the online encyclopedia’s preposterous contention that he was not a credible witness to his own life.

8 Philosophical Thought Experiments That I Illustrated To Broaden Your Mind

The Missing Shade of Blue

Helen De Cruz in Bored Panda:

The thought experiment: A man has seen all colours, except one particular shade of blue. But he has seen other gradations of this colour, and if he were to arrange them in his mind, it would become clear that there’s a gap. Would he be able to fill in the color using his own imagination?

Significance: Hume came up with this thought experiment as a counterexample to his idea that we learn about the world through experience. If that’s the case, we should not be able to fill in the missing shade of blue but it seems we can. Curiously though, when I presented this drawing to friends, they thought the man’s sweater was the missing shade of blue, but it isn’t! So perhaps it is not so easy to fill in the gap after all.

Peter Woit vs Sean Carroll: string theory, the multiverse, and Popperazism

Massimo Pigliucci in Footnotes to Plato:

Ed475595-86a4-4641-bb14-ec948cd8bd7bThe string and multiverse wars are going strong in fundamental physics! And philosophy of science is very much at the center of the storm. I am no physicist, not even a philosopher of physics, in fact (my specialty is evolutionary biology), so I will not comment on the science itself. I take it that the protagonists of this diatribe are more than competent enough to know what they are talking about. But they keep bringing in Karl Popper and his ideas on the nature of science, as well as invoke — or criticize — Richard Dawid’s concept of non-empirical theory confirmation, so I feel a bit of a modest commentary as a philosopher of science is not entirely out of order.

Let me begin with two caveats: first, there are many people involved in the controversy, including Sean Carroll, Peter Woit, Sabine Hossenfelder, George Ellis, and Joe Silk (not to mention astute commentators such as Lee Smolin and Jim Baggott). Refreshingly, almost all of them have respect for philosophy of science, unlike ignorant (of philosophy) physicists like Lawrence Krauss and Stephen Hawking. So, who knows, some of them may even read the following with some interest. Second, I actually know most of these people, obviously some better than others. I like and respect them all, even though — as we shall see — in this post I will come squarely down on one side rather than the other.

And what are these sides? For this round, I’ll focus on an exchange between Sean Carroll and Peter Woit on the specific issue of multiverse theory, though the two disagree — for the same reasons — also about the status of string theory.

Masha Gessen: To Be, or Not to Be

Masha Gessen in the New York Review of Books:

Gessen_1-020818The topic of my talk was determined by today’s date. Thirty-nine years ago my parents took a package of documents to an office in Moscow. This was our application for an exit visa to leave the Soviet Union. More than two years would pass before the visa was granted, but from that day on I have felt a sense of precariousness wherever I have been, along with a sense of opportunity. They are a pair.

I have emigrated again as an adult. I was even named a “great immigrant” in 2016, which I took to be an affirmation of my skill, attained through practice—though this was hardly what the honor was meant to convey. I have also raised kids of my own. If anything, with every new step I have taken, I have marveled more at the courage it would have required for my parents to step into the abyss. I remember seeing them in the kitchen, poring over a copy of an atlas of the world. For them, America was an outline on a page, a web of thin purplish lines. They’d read a few American books, had seen a handful of Hollywood movies. A friend was fond of asking them, jokingly, whether they could really be sure that the West even existed.

Truthfully, they couldn’t know. They did know that if they left the Soviet Union, they would never be able to return (like many things we accept as rare certainties, this one turned out to be wrong). They would have to make a home elsewhere. I think that worked for them: as Jews, they never felt at home in the Soviet Union—and when home is not where you are born, nothing is predetermined. Anything can be. So my parents always maintained that they viewed their leap into the unknown as an adventure.

I wasn’t so sure. After all, no one had asked me.
