Radar in numbers
What it watches right now, and how it scored in testing.
How does the radar work?Right now
On test data: planted swarms and quiet windows
Detection vs false alarms
ROC curve (receiver operating characteristic): the trade-off between catching swarms and raising false alarms. Each point is one detector setting; the ringed one is the setting the radar runs at. Dashed: beyond the last setting measured.
Table
Detection by swarm size
Detection rate (share of planted swarms found) by the number of accounts in the swarm, at the setting the radar runs at.
Table
Sensitivity settings
The dashboard's sensitivity slider has five settings. A higher target lets the radar raise more alarms: it catches more swarms and decides sooner, at the cost of more false alarms. Each row is what that setting actually measured.
