Computer Models Find Patterns In Asymmetric Threats

The Narrative Fallacy brings us a story about a project by University of Alabama researchers to develop a database capable of anticipating targets for future guerrilla attacks. Quoting Space War: "Adversaries the US currently faces in Iraq rely on surprise and apparent randomness to compensate for their lack of organization, technology, and firepower. 'One way to combat these attacks is to identify trends in the attackers' methods, then use those trends to predict their future actions,' said UA-Huntsville researcher Wes Colley. 'Some trends from these attacks show important day-to-day correlations. If we can draw inferences from those correlations, then we may be able to save lives by heightening awareness of possible events or changing the allocation of our security assets to provide more protection.' Researchers reviewed the behavior signatures of terrorists on 12,000 attacks between 2003 and mid-2007 to calculate relative probabilities of future attacks on various target types."

    The attacks are surprises and random, how are they going to try to extrapolate patterns with computers?

    Even better -- if you look in television static long enough, you are going to find a pattern. Either they've found some hidden predictor of attacks, or maybe someone needs a course in basic Ramsey theory, which deals with conditions under which order (patterns) must occur even in random noise.

    Consider this example (*not* meant as an analogy for the discrete math nazis): you have an infinite sequence of completely random letters over the alphabet. What is the probability of finding "abc" repeated 15 times with a gap of exactly 10 letters between successive repeats? If the stream is indeed completely random, then the probability is non-zero and you will EVENTUALLY (probably) see the "pattern".

    Computer models are only as good as their data: Garbage In, Gospel Out. That's a problem with climate modelling. The climatologists keep tweaking the models until they get what they expect and are then smug because the models "prove" their predictions.

    If terrorist activity is truely random, then this thing does not stand a chance. However, terrorists, like most people, likely follow some sort of pattern and if the signature "tell tale signs" can really be detected then perhaps attacks etc can be predicted.

      People like you freak me out. What do you think science is? How, magically, does meteorology differ from Physics? Do we hold the same opinions about black holes, dark matter and the big bang as we used to? Hell, the term "big bang" was originally pejorative--scientists didn't fit that possiblity into their models. The data changed and so that forced a change in theory. It's how fucking science works. For fuck's sake.

      Climate science is no different. What is different is that there are consequences for our actions on earth that matter depending on the outcome of the model. Because there are huge stakes involved, people tend to forms groups at the poles of opinion. You have companies with large stakes in suggesting that climate change is not man made paying for climate research by scientists who feel similarly. You have news organizations and political organizations (who know shit about science) taking the barest of abstracts from a study and runnign with it. You have sceince dumbed down by both sides in order to explain it to voters and policymakers. this sort of thing doesn't happen that much in some branches of science.

      Evolutionary biology, genetics, labor economics, sociology, antropology. Those are a short list of disciplines whose conclusions draw people into camps. They also happen to be the same disciplines (not an exclusive list) that people accuse of unscientific practice (and then in doing so, describe the scientific method perfectly, as you have done). That those disciplines and only those disciplines would suffer from a failure to understand the scientific model alone while scores of other disciplines would execute that model perfectly strains credulity.

      Prediction: The earth is warming due to man made effects.

      Test: Take given data (earth warming) and attempt to sort out all possible other effects.

      These models are EXCEEDINGLY complicated. The early ones were pretty damn complicated but were basic by comparison. Models suggested for years that climate change was man made without a doubt. Later, models were revised with the addition of new data and new processes. this means that NEW information was found that NO ONE had before, like the actual oxygen content in ice cores. Like the feedback nature of ocean currents. Those were taken into account and the model changed. We became less sure of the impact of man in the scheme. As the models grew more sophisicated the confidence intervals got better and more information was added. We are now MUCH, MUCH more sure that climate change is real, man made and will impact us in a significant fashion.

      All we have left are people like you. People who claim that their rejection of climate change is based on some scientific principle, like they are galileo before the church. I've got news for you. It's isn't some religious theocracy. It isn't an unscientific crusade. It is just science that leads to an unfortunate conclusion. We don't WANT to have this conclusion. We don't WANT to come to the conclusion that life will get demonstrably worse in the next 100 years rather than better. We don't WANT to live on a warming planet. These are just conclusions from the model and evidenced by the world around us.

We show that it is possible to accurately model many people's lives with just a few parameters - thus allowing accurate prediction of their future behavior from limited observations of their current behavior - as well as to create a similarity metric between individuals and groups that allows accurate identification of group affiliation and behavioral 'style'.

    But the terrorists have to conform to reality, there are conditions that must be met for an attack to be carried out. Resources and weaponry must be aquired transferred or built. Willing persons must be in the area or transported there. The application of these resources, which are valuable even if they are a disposable one-shot sort deal often, so we know they will be trying to maximize effect in minimizing risk. There may be vastly more targets than terrorists, but that does not mean that every target could be targeted at any one time.

With that many people being killed by terrorists, who needs insurgents?

    The big pattern is that the guerrillas fight dirty. They look for and use any openings: if you close one opening, they'll use the next, least defended one, and it takes them very little time to shift targets because they have little command structure, just enough to keep isolated cells in munitions and shelter.

    The second big pattern is "why do they keep attacking"? If the US instigators of this war had listened to their more competent staff, who told them it's a huge mess and they needed 3 times the number of troops and not to use so many mercenaries (who are a massive problem in Iraq as they've been in other "peacekeeping" operatons), we'd have had a much cleaner recovery after the invasion and wouldn't have these issues.

    But that's an even bigger picture pattern, and these research studies can do nothing about it.
