Researchers Develop Faster Way To Replace Bad Data With Accurate Information (ncsu.edu) 58

sandbagger writes: Researchers from North Carolina State University and the Army Research Office have demonstrated a new model of how competing pieces of information spread in online social networks and the Internet of Things (IoT). The findings could be used to disseminate accurate information more quickly, displacing false information about anything from computer security to public health. "Whether in the IoT or on social networks, there are many circumstances where old information is circulating and could cause problems -- whether it's old security data or a misleading rumor," says Wenye Wang, co-author of a paper on the work and a professor of electrical and computer engineering at NC State. "Our work here includes a new model and related analysis of how new data can displace old data in these networks."

"Ultimately, our work can be used to determine the best places to inject new data into a network so that the old data can be eliminated faster," says Jie Wang, a postdoctoral researcher at NC State and first author of the paper. In their paper, the researchers show that a network's size plays a significant role in how quickly "good" information can displace "bad" information. However, a large network is not necessarily better or worse than a small one. Instead, the speed at which good data travels is primarily affected by the network's structure.

    Seems like a reasonable approach rather than censorship, but it wont stop natural stupidity putting out flawed information in the first place.

      There really is no difference between "good" and "bad" data. This research cuts both ways, you can use it for propaganda or to fight propaganda, depends on your perspective and goals, bits are bits.

    • Seems a highly risky approach. It makes the bold assumption that the new data is accurate and correct. You don't necessarily want old data and information removed simply because it is old. though could be good to get rid of some of the blatant false information like a lot of the anti vaxx crap.

          You mean hypotheses that cant be invalidated arent theories no matter how much data you gather?

          Sounds about right.

          Eisenhower warned us about the "scientific-technological elite" capturing policy in the same speech as the well known "military-industrial complex" warning about that capturing policy. What he didnt realize, I think, is that both can coexist, even so far as bolstering and feeding off each other.

            Yes, the proper term is "(non)-falsifiable".

            A statement has to be falsifiable [wikipedia.org] to be scientific, which automatically excludes any and all predictions containing "may" or "can" instead of "will", for example.

            Geico's commercials are hysterically unfalsifiable ("... could save you up to 15% or more") — and the predictions we see in the press, /. included, are all from the same category.

              For example the UN report saying that if we don't reduce C02 emissions drastically, certain cities in California will be underwater within 30 years. That's a falsifiable claim, if you wait long enough.

              It's been about 30 years since they made that claim, so now it's not only falsifiable, but falsified - San Francisco is in fact not underwater.

              So some of them are falsifiable "eventually*. And most of those have turned out to be false. Which isn't too

                Yes, earlier predictions were falsifiable, but — as they gradually got falsified — the "scientists" became more careful, and the "may" started replacing the "will"... You'd be hard-pressed to find a prediction today, that's not like the Geico commercial I quoted...

          • In context, Eisenhower was concerned that the practice science (which he supported) could be corrupted by the government by promoting a "scientific-technological elite" that does the government's bidding.

            Akin to, and largely responsible for the sweeping changes in our industrial-military posture, has been the technological revolution during recent decades. In this revolution, research has become central, it also becomes more formalized, complex, and costly. A steadily increasing share is conducted for, by, or at the direction of, the Federal government. ...

            The prospect of domination of the nation's scholars by Federal employment, project allocation, and the power of money is ever present and is gravely to be regarded. Yet in holding scientific discovery in respect, as we should, we must also be alert to the equal and opposite danger that public policy could itself become the captive of a scientific-technological elite

            TL/DR: Eisenhower was concerned that policy would capture science, not the other way around.

    From the linked story:

    In their paper, the researchers show that a networkâ(TM)s size plays a significant role in how quickly âoegoodâ information can displace âoebadâ information. However, a large network is not necessarily better or worse than a small one. Instead, the speed at which good data travels is primarily affected by the networkâ(TM)s structure.

    Ok, right away consider Twitter. A massive network that can spread information super quickly.

    Where the model is too simplistic, is that in Twitter each node in the large network can decide to pass information, and very very often that network will spread "invalid" information rapidly across the globe, while any kind of followup with gather but a small percentage of the same spread.

    Twiter at least seems to operate as a large but very gated network, where only information conforming to a certain ideology has access to the full network - otherwise there is significant action to block competing information from spreading, even if it's in fact correct or "good" information.

    So that is nothing about the structure of the network, but instead it comes down to behaviors of the nodes. Even if you were not talking about Twitter, in pretty much any network nodes will always end up acting as some kind of gates to decide what to spread further in the network, and thus the same effect could easily be seen in any larger network of any kind...

    So where the study falls short is in not realizing that any network will not be similarly reachable for all forms of information.

    • by PPH ( 736903 )

      The study talks about network structure and key nodes. It reads a lot like they assume that all nodes will pass information without making decisions or applying filters. But we know that this isn't true. I suspect that what is being left out is the ability to identify and 'take out' nodes that don't meet some standard of approved behavior. In other words, researchers have discovered the cancel culture.

    • by AmiMoJo ( 196126 )

      Twitter doesn't block competing information, it just doesn't show you stuff outside your bubble unless you go looking for it.

      The problem is that Twitter only has one method evaluating the "quality" of a post - likes. Well, it does do some text analysis but it's primitive and doesn't understand meaning. Ideally it would show a good counter-argument along with popular tweets.

      We are at that awkward stage where computers are too dumb and humans too expensive and slow to do this stuff.

    "Our work here includes a new model and related analysis of how new data can displace old data in these networks." So it's not about "bad" or "good" data at all. If the techniques work, they can equally be used to efficiently replace good data with bad.

  • The core assumptions behind this work are that the problem is the dissemination of corrected information, not its acceptance and replication, and that once good information arrives it will replace the bad information. The problem is that information on social networks doesn't work that way. Information isn't replicated and disseminated because it's accurate, but because it convinces people to accept and spread it. Social networks create a form of memetic evolution, where ideas and their expressions (memes, in the original sense of the word, not the sense of labeled images) compete to see which convinces people to spread them the most. Those with the strongest emotional appeal, not the most accurate information, are usually the most successful.

    You can carefully inject the new information at precisely the right points in a social network, the highly-connected nodes that allow information to spread as fast as possible, but unless it provokes the right reactions it will go nowhere.
