The Nation's Science Report Card is out. Everything is going fine. : Greg Laden's Blog - 0 views

  • The Science component of "The Nation's Report Card" was released today and clearly indicates that we have moved one step closer as a nation in two of our most important goals: Building a large and complacent poorly educated low-pay labor class, and increasing the size of our science-illiterate populace in order to allow the advance of medieval morality and Iron Age Christian values.

Watson Still Can't Think - NYTimes.com - 0 views

  • Fish argued that Watson “does not come within a million miles of replicating the achievements of everyday human action and thought.” In defending this claim, Fish invoked arguments that one of us (Dreyfus) articulated almost 40 years ago in “What Computers Can’t Do,” a criticism of 1960s and 1970s style artificial intelligence.
  • At the dawn of the AI era the dominant approach to creating intelligent systems was based on finding the right rules for the computer to follow.
  • GOFAI, for Good Old Fashioned Artificial Intelligence.
  • ...12 more annotations...
  • For constrained domains the GOFAI approach is a winning strategy.
  • there is nothing intelligent or even interesting about the brute force approach.
  • the dominant paradigm in AI research has largely “moved on from GOFAI to embodied, distributed intelligence.” And Faustus from Cincinnati insists that as a result “machines with bodies that experience the world and act on it” will be “able to achieve intelligence.”
  • The new, embodied paradigm in AI, deriving primarily from the work of roboticist Rodney Brooks, insists that the body is required for intelligence. Indeed, Brooks’s classic 1990 paper, “Elephants Don’t Play Chess,” rejected the very symbolic computation paradigm against which Dreyfus had railed, favoring instead a range of biologically inspired robots that could solve apparently simple, but actually quite complicated, problems like locomotion, grasping, navigation through physical environments and so on. To solve these problems, Brooks discovered that it was actually a disadvantage for the system to represent the status of the environment and respond to it on the basis of pre-programmed rules about what to do, as the traditional GOFAI systems had. Instead, Brooks insisted, “It is better to use the world as its own model.”
  • although they respond to the physical world rather well, they tend to be oblivious to the global, social moods in which we find ourselves embedded essentially from birth, and in virtue of which things matter to us in the first place.
  • the embodied AI paradigm is irrelevant to Watson. After all, Watson has no useful bodily interaction with the world at all.
  • The statistical machine learning strategies that it uses are indeed a big advance over traditional GOFAI techniques. But they still fall far short of what human beings do.
  • “The illusion is that this computer is doing the same thing that a very good ‘Jeopardy!’ player would do. It’s not. It’s doing something sort of different that looks the same on the surface. And every so often you see the cracks.”
  • Watson doesn’t understand relevance at all. It only measures statistical frequencies. Because it is relatively common to find mismatches of this sort, Watson learns to weigh them as only mild evidence against the answer. But the human just doesn’t do it that way. The human being sees immediately that the mismatch is irrelevant for the Erie Canal but essential for Toronto. Past frequency is simply no guide to relevance.
  • The fact is, things are relevant for human beings because at root we are beings for whom things matter. Relevance and mattering are two sides of the same coin. As Haugeland said, “The problem with computers is that they just don’t give a damn.” It is easy to pretend that computers can care about something if we focus on relatively narrow domains — like trivia games or chess — where by definition winning the game is the only thing that could matter, and the computer is programmed to win. But precisely because the criteria for success are so narrowly defined in these cases, they have nothing to do with what human beings are when they are at their best.
  • Far from being the paradigm of intelligence, therefore, mere matching with no sense of mattering or relevance is barely any kind of intelligence at all. As beings for whom the world already matters, our central human ability is to be able to see what matters when.
  • But, as we show in our recent book, this is an existential achievement orders of magnitude more amazing and wonderful than any statistical treatment of bare facts could ever be. The greatest danger of Watson’s victory is not that it proves machines could be better versions of us, but that it tempts us to misunderstand ourselves as poorer versions of them.

The Social Network and the Dunbar Number | Mind & Matter - WSJ.com - 0 views

  • Mr. Dunbar's eponymous number is 147.8, plus or minus a lot, and it is the size of the average human being's social network of friends, as predicted by the size of the average human brain
  • Mr. Dunbar famously noticed that there is a tight correlation between the size of a primate's brain and the size of the social group its species generally forms. On this basis human beings should live in groups of around 150. The neat thing about this prediction was the way it seemed to fit the number of good friends most people have, as measured by the length of address books, the size of hunter-gatherer bands, the population of neolithic villages and the strength of army units. In recent years, Facebook has also seemed to confirm the hunch, with rosters of friends often settling around the Dunbar number.
  • Mr. Dunbar's "social brain hypothesis" rests on another idea—the theory of mind—which argues that we use our brains to imagine what others are thinking. So, drilling down further into the physiology of the brain, Mr. Dunbar's team has now found that a rich social network also goes with the ability to reason about others' intentional states.

Book Review: The Last Lingua Franca - WSJ.com - 0 views

  • After narrating the history of Latin, Persian, Phoenician and other once-dominant languages, all now either dead or consigned to their native communities, Mr. Ostler argues that English too will sputter out relatively soon. Among the factors dooming it is the lack of any institution to demand its survival—no priestly use, as Latin or Sanskrit had, or government that requires its subjects to keep their linguistic skills up to enjoy full citizenship. As English loses cachet, it will become optional, and ultimately its reign will be one of the shortest in the history of lingua francas.
  • But regional languages are gaining enough traction in trade to allow their speakers to discard English, particularly if people can transact their cultural and commercial business with the crutch of computer software and machine translation.
  • The one issue that Mr. Ostler treats insufficiently is what the world might lose after what his subtitle calls "the return of Babel." One needn't be sentimental about English to wonder whether it isn't useful to have one language, rich in literature, that everyone shares in addition to a mother tongue.

The Lies of Science Writing - WSJ.com - 0 views

  • Writing about science poses a fundamental problem right at the outset: You have to lie.
  • because math is the language of science, scientists who want to translate their work into popular parlance have to use verbal or pictorial metaphors that are necessarily inexact.
  • Choosing the proper metaphor can make all the difference between distorting science and providing an appropriate context from which nonscientists can appreciate new scientific findings and put them in perspective.
  • ...4 more annotations...
  • Not only is a good picture, even a mental one, worth at least a thousand words, but many scientists themselves think in these terms.
  • Though metaphors are useful in trying to understand complicated scientific ideas, they have their pitfalls.
  • Consider another famous scientific metaphor, the evolutionary biologist Richard Dawkins's idea of the "selfish gene." This is a brilliant and simple way to explain that natural selection relies on the self-perpetuation of genes that promote higher rates of survival. But for some critics, it suggests an intentionality that is absent in the process of evolution. Others worry that it implies an immoral world where selfishness wins out.
  • When used effectively, an apt metaphor can enhance the real purpose in writing about science for the public: provoking interest and a desire to learn more.

Armies of Expensive Lawyers, Replaced by Cheaper Software - NYTimes.com - 0 views

  • thanks to advances in artificial intelligence, “e-discovery” software can analyze documents in a fraction of the time for a fraction of the cost.
  • Computers are getting better at mimicking human reasoning — as viewers of “Jeopardy!” found out when they saw Watson beat its human opponents — and they are claiming work once done by people in high-paying professions. The number of computer chip designers, for example, has largely stagnated because powerful software programs replace the work once done by legions of logic designers and draftsmen.
  • Software is also making its way into tasks that were the exclusive province of human decision makers, like loan and mortgage officers and tax accountants.

  • E-discovery technologies generally fall into two broad categories that can be described as “linguistic” and “sociological.”
  • The most basic linguistic approach uses specific search words to find and sort relevant documents. More advanced programs filter documents through a large web of word and phrase definitions.

Humans, Version 3.0 § SEEDMAGAZINE.COM - 0 views

  • Where are we humans going, as a species? If science fiction is any guide, we will genetically evolve like in X-Men, become genetically engineered as in Gattaca, or become cybernetically enhanced like General Grievous in Star Wars.
  • There is, however, another avenue for human evolution, one mostly unappreciated in both science and fiction. It is this unheralded mechanism that will usher in the next stage of human, giving future people exquisite powers we do not currently possess, powers worthy of natural selection itself. And, importantly, it doesn’t require us to transform into cyborgs or bio-engineered lab rats. It merely relies on our natural bodies and brains functioning as they have for millions of years. This mystery mechanism of human transformation is neuronal recycling, coined by neuroscientist Stanislas Dehaene, wherein the brain’s innate capabilities are harnessed for altogether novel functions.
  • The root of these misconceptions is the radical underappreciation of the design engineered by natural selection into the powers implemented by our bodies and brains, something central to my 2009 book, The Vision Revolution. For example, optical illusions (such as the Hering) are not examples of the brain’s poor hardware design, but, rather, consequences of intricate evolutionary software for generating perceptions that correct for neural latencies in normal circumstances.
  • ...4 more annotations...
  • Like all animal brains, human brains are not general-purpose universal learning machines, but, instead, are intricately structured suites of instincts optimized for the environments in which they evolved. To harness our brains, we want to let the brain’s brilliant mechanisms run as intended—i.e., not to be twisted. Rather, the strategy is to twist Y into a shape that the brain does know how to process.
  • there is a very good reason to be optimistic that the next stage of human will come via the form of adaptive harnessing, rather than direct technological enhancement: It has already happened. We have already been transformed via harnessing beyond what we once were. We’re already Human 2.0, not the Human 1.0, or Homo sapiens, that natural selection made us. We Human 2.0’s have, among many powers, three that are central to who we take ourselves to be today: writing, speech, and music (the latter perhaps being the pinnacle of the arts). Yet these three capabilities, despite having all the hallmarks of design, were not a result of natural selection, nor were they the result of genetic engineering or cybernetic enhancement to our brains. Instead, and as I argue in both The Vision Revolution and my forthcoming Harnessed, these are powers we acquired by virtue of harnessing, or neuronal recycling.
  • Although the step from Human 1.0 to 2.0 was via cultural selection, not via explicit human designers, does the transformation to Human 3.0 need to be entirely due to a process like cultural evolution, or might we have any hope of purposely guiding our transformation? When considering our future, that’s probably the most relevant question we should be asking ourselves.
  • One of my reasons for optimism is that nature-harnessing technologies (like writing, speech, and music) must mimic fundamental ecological features in nature, and that is a much easier task for scientists to tackle than emulating the exhorbitantly complex mechanisms of the brain

David Brooks on The Social Animal: Interview - The Daily Beast - 0 views

  • who we are is largely determined by the hidden workings of our unconscious minds. Everything we do in life—the careers we choose; even, on a deeper level, the way we experience and perceive the sensation of being alive—emerges from an infinitely complex neuronal network sending out signals (Brooks calls them “scouts”) that, largely unknown to us, assess and determine our behavior. Insights, information, responses to stimuli are governed by our emotions, a rich repository of thoughts and feelings that courses just beneath the surface of our conscious minds. They are “mental sensations that happen to us.”
  • Behind the elaborate theorizing is Brooks’s desire to articulate a universal feeling: that all of us are caught up in what he calls “the loneliness loop.” We yearn for “community”; we have “the urge to merge.” When two people are having an intense conversation, their breathing synchronizes; laughing to-gether creates a feeling of joy; soldiers drilling in unison experience a surge of power. What drives us, ultimately, is the need to be understood by others.
  • Brooks has always been more of a public intellectual than a pundit, driven by genuine curiosity about human beings and the world.

  • Writing The Social Animal has been an exhilarating journey. “The scientists I’ve spent the last three years talking to are truth seekers, unlike people [in Washington]. They’re not technical materialists. They love Henry and William James. They’ve helped me see how the power of deep ideas changes the way you think. It was part of my idea to go down, down, down, to look at moral and spiritual creativity, the deepest issues. You learn the importance of culture, of history—some of the deep knowledge that comes from Plato and Aristotle. Philosophy and theology are telling us less than they used to. Scientists and researchers are leaping in where these disciplines atrophy—they’re all drilling down into an explanation of what man is.”

Book Review: The Moral Lives of Animals - WSJ.com - 0 views

  • have elucidated very real differences between human and nonhuman minds in the realm of conceptual reasoning, particularly with respect to what has been termed "theory of mind." This is the uniquely human ability to have thoughts about thoughts and to perceive that other minds exist and that they can hold ideas and beliefs different from one's own. While human and animal minds share a broadly similar ability to learn from experience, formulate intentions and store memories, careful experiments have repeatedly come up empty when attempting to establish the existence of a theory of mind in nonhumans.
  • A "theory of mind" is what makes it even possible to formulate abstract notions, to imagine the future, to try out ideas before acting upon them, to reflect about our own conduct and to see things from another's viewpoint. Charles Darwin observed that such a capacity is indeed the sine qua non of moral thought: "A moral being is one who is capable of reflecting on his past actions and their motives—of approving some and disapproving of others," he wrote in "The Descent of Man."

Buddhism and the Brain § SEEDMAGAZINE.COM - 0 views

  • Anatta is not a unified, unchanging self. It is more like a concert, constantly changing emotions, perceptions, and thoughts. Our minds are fragmented and impermanent. A change occurred in the band, so it follows that one expects a change in the music. Both Buddhism and neuroscience converge on a similar point of view: The way it feels isn’t how it is. There is no permanent, constant soul in the background. Even our language about ourselves is to be distrusted (requiring the tortured negation of anatta). In the broadest strokes then, neuroscience and Buddhism agree.
  • How did Buddhism get so much right? I speak here as an outsider, but it seems to me that Buddhism started with a bit of empiricism. Perhaps the founders of Buddhism were pre-scientific, but they did use empirical data. They noted the natural world: the sun sets, the wind blows into a field, one insect eats another. There is constant change, shifting parts, and impermanence. They called this impermanence anicca, and it forms a central dogma of Buddhism.

Review: Vernor Vinge's 'Fast Times' | KurzweilAI - 0 views

  • Vernor Vinge’s Hugo-award-winning short science fiction story “Fast Times at Fairmont High” takes place in a near future in which everyone lives in a ubiquitous, wireless, networked world using wearable computers and contacts or glasses on which computer graphics are projected to create an augmented reality.
  • So what is life like in Vinge’s 2020?The biggest technological change involves ubiquitous computing, wearables, and augmented reality (although none of those terms are used). Everyone wears contacts or glasses which mediate their view of the world. This allows computer graphics to be superimposed on what they see. The computers themselves are actually built into the clothing (apparently because that is the cheapest way to do it) and everything communicates wirelessly.

  • One thing that was believable is that it seemed that a lot of the kids cheated, and it was almost impossible for the adults to catch them. With universal network connectivity it would be hard to make sure kids are doing their work on their own. I got the impression the school sort of looked the other way, the idea being that as long as the kids solved their problems, even if they got help via the net, that was itself a useful skill that they would be relying on all their lives.

Experimental Philosophy: The Instability of Philosophers' Judgments about Hypothetical ... - 0 views

They are subject, for example, to substantial order effects, and they vary by culture and gender. Question: Are professional philosophers' judgments about such hypothetical scenarios particularly better grounded?
  • Non-philosophers, we suspected, would respond differently to the scenarios depending upon the order of presentation, a sign of instability and unreliability in judgment. Our question was: Would professional philosophers show smaller order effects and thus more stable judgments?
  • They did not. In fact, the overall trend across our data (marginally statistically significant) was for philosophers to show less stability their responses. This was true even for the subgroup of 91 respondents reporting a PhD in philosophy and a competence or specialization in ethics.
