  • Automated identification of terrorists through data mining (or any other known methodology) is neither feasible as an objective nor desirable as a goal of technology development efforts.
  • criminal prosecutors and judges are concerned with determining the guilt or innocence of a suspect in the wake of an already-committed crime; counter-terror officials are concerned with preventing crimes from occurring by identifying suspects before they've done anything wrong.
  • The problem: preventing a crime by someone with no criminal record
  • ...3 more annotations...
  • In fact, most terrorists have no criminal record of any kind that could bring them to the attention of authorities or work against them in court.
  • As the NRC report points out, not only is the training data lacking, but the input data that you'd actually be mining has been purposely corrupted by the terrorists themselves.
  • So this application of data mining bumps up against the classic GIGO (garbage in, garbage out) problem in computing, with the terrorists deliberately feeding the system garbage.

  • Data Mining is a process of discovering meaningful new correlations, patterns and trends by sifting through large amounts of data stored in repositories, using statistical, data analysis and mathematical techniques
  • Data mining is the crucial process that helps companies better comprehend their customers. Data mining can be defined as ‘the nontrivial extraction of implicit, previously unknown, and potentially useful information from data’ and also as ‘the science of extracting useful information from large sets or databases’.

  • Our Zotero Server, connected to the client, will enable all kinds of new collaboration opportunities and data-mining of aggregated collections. We also plan to provide hooks into high-performance computing projects like the SEASR text-mining project based at UIUC
  • Data mining is becoming a major trend in eResearch as computing power increases and more and more researchers have direct access to open data sets. In the future, we won’t just be citing articles, figures, images, movies, and books, we’ll also be citing specific data points.

The End Of The Scientific Method… Wha….? « Life as a Physicist - 0 views

data mining thinking

  • His basic thesis is that when you have so much data you can map out every connection, every correlation, then the  data becomes the model. No need to derive or understand what is actually happening — you have so much data that you can already make all the predictions that a model would let you do in the first place. In short — you no longer need to develop a theory or hypothesis - just map the data!
  • First, in order for this to work you need to have millions and millions and millions of data points. You need, basically, ever single outcome possible, with all possible other factors. Huge amounts of data. That does not apply to all branches of science.
  • The second problem with this approach is you will never discover anything new. The problem with new things is there is no data on them!
  • ...3 more annotations...
  • Correlations are a way of catching a scientist’s attention, but the models and mechanisms that explain them are how we make the predictions that not only advance science, but generate practical applications. One only needs to look at a promising field that lacks a strong theoretical foundation—high-temperature superconductivity springs to mind—to see how badly the lack of a theory can impact progress
  • Anderson is right — we are entering a new age where the ability to mine these large amounts of data are going to open up whole new levels of understanding
  • This is a new tool, and it will open up all sorts of doors for us. But the end of the scientific method? No — because that implies an end of discovery. And end of new things.
