They found key evidence for quadrupole correlation signatures compatible with the prediction of nanohertz gravitational waves at a 4.6-sigma statistical confidence level, with a false alarm probability of two in a million.
Well, my specialty is to look for unusual molecules that have fewer false positives for life because they're so difficult to make that they're rarely made spontaneously.
Oh, it must be a wrong alert, maybe I have to do some adjustments, but the notification on my phone was telling me that there was a movement in my flat and also a face that the app did not recognize.
While noting that most vessels shorter than 15m probably escaped their view, they estimated a false positive rate of less than 2% for those they did identify.
The trouble is that these searches yield a blizzard of data — including false positives produced by Earthly interference from mobile phones, GPS and other aspects of modern life.
Blockchain allows for the generation of a whitelist that will include all trusted customers worldwide. Having such a whitelist will decrease false positives and, consequently, help detect real fraud.
Any predictive model will generate false positives, in which innocent people are flagged for investigation. Careful design can drive the false-positive rate down.
