RESHARED POST FROM REBECCA MACKINNON

In an interview with the Guardian, Berners-Lee said: “My computer has a great understanding of my state of fitness, of the things I’m eating, of the places I’m at. My phone understands from being in my pocket how much exercise I’ve been getting and how many stairs I’ve been walking up and so on.” Exploiting such data could provide hugely useful services to individuals, he said, but only if their computers had access to personal data held about them by web companies. “One of the issues of social networking silos is that they have the data and I don’t … There are no programmes that I can run on my computer which allow me to use all the data in each of the social networking systems that I use plus all the data in my calendar plus in my running map site, plus the data in my little fitness gadget and so on to really provide an excellent support to me.” Rebecca MacKinnon originally shared this post: Tim Berners-Lee: demand your data from Google and Facebook Exclusive: world wide web inventor says personal data held online could be used to usher in new era of personalised services

RESHARED POST FROM DREW SOWERSBY

“Many broadly significant scientific questions, ranging from self-organization and information flow to systemic robustness, can now be properly formalized within the emerging theory of networks,” says Adilson E. Motter, professor of physics and astronomy. “I was thus humbled to be invited to write such a timely piece.” The authors argue that, as network research matures, there will be increasing opportunities to exploit network concepts to also engineer new systems with desirable properties that may not be readily available in existing ones. Drew Sowersby originally shared this post: Networks and the patterns they express #Networks #Patterns #Collaboration #Complexity They are just beginning to establish how to properly read patterns within networks. I found the following insight to mesh with my own intuition about how to proceed! “One such method mentioned in the article aims at resolving the internal structure of complex networks by organizing the nodes into groups that share something in common, even if researchers do not know a priori what that thing is.” Futurity.org – To control a network, find the pattern Research news from leading universities

RESHARED POST FROM WAYNE RADINSKY

” We all know that, for example, the iPad is assembled from lots of high tech suppliers. The piece below thinks about that in terms of the knowledge required to build an iPad. That knowledge is more than a single company can handle and it must be spread among a number of companies. In the early days, life was simple. We did important things like make spears and arrowheads. The amount of knowledge needed to make these items, however, was small enough that a single person could master their production. There was no need for a large division of labor and new knowledge was extremely precious. If you got new knowledge, you did not want to share it. After all, in a world where most knowledge can fit in someone’s head, stealing ideas is easy, and appropriating the value of the ideas you generate is hard. At some point, however, the amount of knowledge required to make things began to exceed the cognitive limit of a single human being. Things could only be done in teams, and sharing information among team members was required to build these complex items. Organizations were born as our social skills began to compensate for our limited cognitive skills. Society, however, kept on accruing more and more knowledge, and the cognitive limit of organizations, just like that of the spearmaker, was ultimately reached. … Today … most products are combinations of knowledge and intellectual property that resides in different organizations. Our world is less and less about the single pieces of intellectual property and more and more about the networks that help connect these pieces. The total stock of information used in these ecosystems exceeds the capacity of single organizations because doubling the size of huge organizations does not double the capacity of that organization […]

RESHARED POST FROM MICHAEL CHUI

I wrote the following rant in +Michael Chui‘s thread. ______ There is nothing wrong with the entrepreneurial spirit. In the biological world they call entrepreneuralism “opportunism”, and being opportunistic is vital for evolutionary for success. The problem is that entrepreneurialism must exist within an incentive structure that encourages and incentivizes deplorable and inhumane acts, which has rapidly led to an overwhelming correlation between entrepreneurs and the most vile excess of capitalism. The article you post here is suggesting we discourage opportunism; I think this is a losing suggestion; it’s not the kind of thing that can will catch on. The far more promising solution is to change the incentive structure to stop encouraging inhumanity, instead of trying to force ourselves to make up for the deficiencies of our organizational schema. We can’t do it; it’s pretty clear by now that even our best efforts are promptly quashed by the crushing inertia of the existing order of things. I’ve seen at least a few posts over the last few days clearly describing the transition to a “cashless” economy. The universal presumption of all these articles is that the basic inventive of money will stay the same, and that the only change will be at the interface: instead of handling little pieces of paper, the flow of cash will all be digital. The small-mindedness of these articles frustrates me to no end. Obviously the transactions will be increasingly digital; they already are largely digital, and it isn’t hard to imagine the pieces of paper going away. Such a change would be about as interesting as announcing that they are painting all the money pink; its a completely superficial difference. But seriously, everyone, if we are going to make such a transition anyway, why not redesign the thing from scratch? With a little […]

RESHARED POST FROM KENNETH READ

Thus the proposed PageRank Opinion Formation (PROF) model takes into account the situation in which an opinion of an in?uential friend from high ranks of the society counts more than an opinion of a friend from lower society level. We argue that the PageRank probability is the most natural form of ranking of society members. Indeed, the e?ciency of PageRank rating is demonstrated for various types of scale-free networks including the World Wide Web (WWW), Physical Review citation network, scienti?c journal rating, ranking of tennis players, Wikipedia articles, the world trade network and others. Due to the above argument we consider that the PROF model captures the reality of social networks and below we present the analysis of its interesting properties. _______ I’ve posted four distinct articles describing various methods for modeling the #attentioneconomy today, in case anyone happened to notice. Hopefully the scientists involved are also working on popularized texts to help the public understand what they are doing.

TURING’S INTELLIGENT MACHINES THIS WILL…

Turing’s intelligent machines This will be the first in a series of essays discussing Turing’s view of artificial intelligence. You can find some relevant links for further consideration at the bottom of the post. Questions, comments, and suggestions are appreciated! !: Turing’s prediction In his 1950’s paper Computing Machinery and Intelligence, Turing gives one of the first systematic philosophical treatments of the question of artificial intelligence. Philosophers back to Descartes have worried about whether “automatons” were capable of thinking, but Turing pioneered the invention of a new kind of machine that was capable of performances unlike any machine that had come before. This new machine was called the digital computer, and instead of doing physical work like all other machines before, the digital computer was capable for doing logical work. This capacity for abstract symbolic processing, for reasoning, was taken as the fundamentally unique distinction of the human mind since the time of Aristotle, and yet suddenly we were building machines that were capable of automating the same formal processes. When Turing wrote his essay, computers were still largely the stuff of science fiction; the term “computer” hadn’t really settled into popular use, mostly because people weren’t really using computers. Univac’s introduction in the 1950’s census effort and its prediction of the 1952 presidential election was still a few years into the future, and computing played virtually no role in the daily lives of the vast majority of people. In lieu of a better name, the press would describe the new digital computers as “mechanical brains”, and this rhetoric fed into the public’s uncertainty and fear of these unfamiliar machines. Despite his short life, Turing’s vision was long. His private letters show that he felt some personal stake in the popular acceptance of these “thinking machines”, and his 1950 essay […]

RESHARED POST FROM BRUNO GONÇALVES

Recent empirical evidence has shown that enabling collective intelligence by introducing social influence, can be detrimental to the aggregate performance of a population (Lorenz et al. 2011). By social influence, we understand the pervasive tendency of individuals to conform to the behavior and expectations of others (Kahan 1997). In separate experiments, Lorenz et al. asked participants to re-evaluate their opinions on quantitative subjects over several rounds and under three information spreading scenarios — no information about others’ estimations (control group), the average of all opinions in each round and full information on other subjects’ judgements. They found evidence that under the latter two regimes, the diversity in the population decreased, while the collective deviation from the truth increased. This result justi ed the disheartening conclusion that allowing people to learn about others’ behaviours and adapt their own as a response does not always lead to the group acting “wiser”. Rather, as the authors posited, not only is the population jointly convinced of a wrong result, but even the simple aggregation technique of the wisdom of crowds is deteriorated. From a policy-maker’s perspective, such groups are, thus, not wise. Current research has not yet investigated thoroughly the theoretical link between social influence and its eff ect on the wisdom of crowds. In this paper, we build upon the empirical study in (Lorenz et al. 2011) by developing a formal model of social influence. Our goal is to unveil whether the e ffects of social in influence are unconditionally positive or negative, or whether its ultimate role is mediated through some mechanism, so that the e ffect on the group wisdom is only indirect. We adopt a minimalistic agent-based model, which successfully reproduces the fin dings of the said study and gives enough insight to draw more general conclusions. In particular, we confirm that small amounts […]

TODAY MARKS AN IMPORTANT MILESTONE FOR WOLFRAM…

Today marks an important milestone for Wolfram|Alpha, and for computational knowledge in general: for the first time, Wolfram|Alpha is now on average giving complete, successful responses to more than 90% of the queries entered on its website (and with “nearby” interpretations included, the fraction is closer to 95%). I consider this an impressive achievement—the hard-won result of many years of progressively filling out the knowledge and linguistic capabilities of the system. The picture below shows how the fraction of successful queries (in green) has increased relative to unsuccessful ones (red) since Wolfram|Alpha was launched in 2009. And from the log scale in the right-hand panel, we can see that there’s been a roughly exponential decrease in the failure rate, with a half-life of around 18 months. It seems to be a kind of Moore’s law for computational knowledge: the net effect of innumerable individual engineering achievements and new ideas is to give exponential improvement. http://blog.stephenwolfram.com/2012/04/overcoming-artificial-stupidity/ thx +Peter Asaro Stephen Wolfram Blog : Overcoming Artificial Stupidity Progressive improvements allow Wolfram|Alpha to give successful responses 90% of the time.

A PARABLE:

You and I are two young, educated Europeans in the late 17th century, right at the dawn of the Enlightenment. We are up to date on some of the new philosophy, where talk of “individual freedom” and “human rights” has dominated the intellectual discussion of what an ideal society looks like. We have also witnessed the new sciences start to develop, only to be routinely hampered by the oppressive power of the Church. We feel like we are on the brink of major social revolution, a fundamental revaluation of human life and society, but the power of the Church and of the Kings and Lords is incredibly strong, and the future is uncertain. One day, I come to you in hushed tones. “I fear that we may never realize the ideals of our Enlightenment,” I say, “because I do not believe such an ideal society is possible under the oppressive rule of the Church. The Church will never recognize a conception of human freedom that challenges their absolute authority.” “Nonsense!” you reply. “The ideal of human rights and a liberal society is a noble goal, and one worth pursuing for the good of all people. But the Church is a fact of life, and it has been this way for generations, back to Constantine himself. However we choose to realize the ideal state, we must do it while acknowledging the power and authority of the Church. Only by cooperating with the Church and its wishes will we be able to advance our cause. That’s how it has always been, that’s how it always will be.” I object again, suggesting that individual liberty cannot be realized within a theocratic state. “In order to realize a genuinely liberal society, we must have asecular society! The road to human rights requires bringing down […]

ANT MILL

When an ant is placed in a foreign environment without a trail to lead it home, it will wander aimlessly (probably the best method for stumbling onto the lost trail). When it encounters another ant from the same colony, it follows (maybe that ant knows the way back!) When the entire colony is massively displaced and loses its trail, it swarms around itself like a spiral galaxy, since all the ants revert to the best-guess default behavior of “following another ant”, and none of them have any idea where to go. Unless disrupted, the ants will continue to spiral around themselves until they all die from exhaustion. #antmill #ants #selforganization Original post:https://plus.google.com/u/0/117828903900236363024/posts/dy13nz8r6H9

Everyone got a nice long look at the incredible engineering feats responsible for both building and then repairing the Deepwater Horizon mining operation. Okay, space mining might be more challenging in the details (bigger profits, vastly more epic failures), but is this really “changing the way we think about natural resources”? Or is it more of the same at a more dramatic scale? For that matter, how do we think about natural resources now?” Are asteroids a “natural resource”?

DO KIDS CARE IF THEIR ROBOT FRIEND GETS…

Do Kids Care If Their Robot Friend Gets Stuffed Into a Closet? More from the Robovie research group! “Overall, 80 percent of the participants felt that Robovie was intelligent, and 60 percent thought that Robovie had feelings. At the same time, over 80 percent believed that it was just fine for people to own and sell Robovie. Hmm. Only 50 percent of the children felt that it was not all right to put Robovie in the closet, although close to 90 percent agreed with Robovie that it wasn’t fair to put it in the closet and it should have been allowed to at least finish the game it was playing. Things get even more interesting when you break down the results by age. For example, while 93 percent and 67 percent of 9 year olds said that they believed Robovie to be intelligent and to have feelings, respectively, those percentages drop to 70 percent and just 43 percent when you ask 15 year olds the same thing. Older children were also much less likely to think of Robovie as a friend, but more likely to object to a person being able to sell Robovie.” From the published article: “What then are these robots? One answer, though highly speculative, is that we are creating a new ontological being with its own unique properties. Recall, for example, that we had asked children whether they thought Robovie was a living being. Results showed that 38% of the children were unwilling to commit to either category and talked in various ways of Robovie being “in between” living and not living or simply not fitting either category. As one child said, “He’s like, he’s half living, half not.” It is as if we showed you an orange object and asked you, “Is this object red […]

RESHARED POST FROM BORA ZIVKOVIC

“In one simple task, a plate of food was presented to the wolf pups (at 9 weeks) or to the dog puppies (both at 5 weeks and at 9 weeks). However, the food was inaccessible to the animals; human help would be required to access it. The trick to getting the food was simple: all the animals had to do was make eye contact with the experimenter, and he or she would reward the dog with the food from the plate. Initially, all the animals attempted in vain to reach the food. However, by the second minute of testing, dogs began to look towards the humans. This increased over time and by the fourth minute there was a statistical difference. Dogs were more likely to initiate eye contact with the human experimenter than the wolves were. This is no small feat; initiating eye contact with the experimenter requires that the animal refocus its attention from the food to the human. Not only did the wolf pups not spontaneously initiate eye contact with the human experimenter, but they also failed to learn that eye contact was the key to solving their problem.” Bora Zivkovic originally shared this post: Dogs, But Not Wolves, Use Humans As Tools | The Thoughtful Animal, Scientific American Blog Network Sometime between fifteen and thirty thousand years ago, probably in the Middle East, the long, protracted process of domestication began to alter the genetic code of … POST NAVIGATION

RESHARED POST FROM BRAD MORRIS

Disappearing inhibitors Earlier research found that approximately one fifth of the synapses in the brain inhibit rather than excite other nerve-cell activity. Neuroscientists have now shown that many of these inhibitory synapses disappear if the adult brain is forced to learn new skills. They reached this conclusion by labelling inhibitory synapses in mouse brains with fluorescent proteins and then tracking them for several weeks using a specialised microscope. They then closed one of the mice’s eyes temporarily to accustom them to seeing through just one eye. After a few days, the area of the brain that processes information from both eyes began to respond more actively to the open eye. At the same time, many of the inhibitory synapses disappeared and were later replaced by new synapses. Regulating the information network Inhibitory synapses are vital for the way networks function in the brain. “Think of the excitatory synapses as a road network, with traffic being guided from A to B, and the inhibitory synapses as the matrix signs that regulate the traffic,” explains research leader Christiaan Levelt. “The inhibitory synapses ensure an efficient flow of traffic in the brain. If they don’t, the system becomes overloaded, for example as in epilepsy; if they constantly indicate a speed of 20 kilometres an hour, then everything will grind to a halt, for example when an anaesthetic is administered. If you can move the signs to different locations, you can bring about major changes in traffic flows without having to entirely reroute the road network.” Brad Morris originally shared this post: Learning mechanism of the adult brain revealed They say you can’t teach an old dog new tricks. Fortunately, this is not always true. Researchers have now discovered how the adult brain can adapt to new situations. Their study may be significant in…
