It’s basic statistics.
- True Positives (TP) 415
- False Positives (FP) 1,012
- False Negatives (FN) (Calculated using 96% Recall) 17 Target plates that were missed.
- Precision TP / (TP + FP) 29.1% When it hits, it’s wrong most of the time.
- Recall (Assumed from Global Acc.) 96.0% It successfully catches almost all targets.
That’s the problem if you are fishing for a very small number of targets out of an absolutely bonkers large pool of potential targets - at some point your false positives start becoming more and more prevalent in relation to actual positives. That is simply statistics and if flock can’t improve the global accuracy by some exponents, this problem will grow - the more Flock gets used and the more licence plates they are scanning, the more the false positives increase.
And it is a massive problem, because the false positive marks you as a criminal - that means any legal recourse gets expensive and painful. This technology creates more problems for everyday people than the amount of issues it removes by tracking actual criminals.
Cutting them down with a reciprocating saw is absolutely justified. These things are an affront to privacy and accuse random citizens of being guilty of felonies.
