Why HN links it

HN readers link this blog for posts on surveillance effectiveness and base-rate reasoning. One commenter cites a post questioning how likely NSA surveillance is to catch terrorists, and others explain base-rate problems in face recognition.

Summarised by Claude from a sample of 3 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?

  1. With each passing successful terrorist attack the effectiveness of this surveillance system will be questioned. It's already considered highly ineffective... http://bayesianbiologist.com/2013/06/06/how-likely-is-the-ns... In the meantime keep protesting (to be seen and heard) and use technology to thwart said surveillance. Don't listen to the "if you use encryption they'll definitely watch you" logic. Your messages…

  3. Even if you get the false positive rate low, the low prevalence of criminals versus innocents will lead to a large number of false positives. Let's say one person in 1000 has an outstanding warrant. Let's say that when the camera sees this person, it has a 99% chance of recognising them correctly. Let's also say that it has only a 1% chance of recognising an innocent person as a suspect. Under these generous conditi…

  5. I also wrote a little blog post about that very thing back in 2011. In addition to using a Markov chain approach, also took a look at it from an information entropy perspective. And the code is also in R, to boot! http://bayesianbiologist.com/2011/12/31/uncertainty-in-marko...

  9. I think you may be going into precog territory while looking for a needle in a haystack. Some of the common patterns seem fairly well documented: disaffected male, mental issues, history of abuse, affiliation with radical islam. But most experts seem to believe finding a key indicator before hand is really impossible since you will also label so many people who will actually resist the urge to violence. The Orlando…
