Imagine you're building a classifier to identify whether there's somebody waiting to cross a road given images from a CCTV camera. When a person is detected, the lights should turn red to allow them to safely cross. The positive class indicates a person is present and the negative class indicates nobody is there. What would a system with high specificity and low sensitivity correspond to in this scenario? OO The system will often turn the traffic lights to red regardless of whether someone is waiting The system will change the traffic lights to red whenever a person is not present The system will rarely turn the traffic lights red when nobody is waiting, but some people might need to wait for a long time. The system will change the traffic lights to red at night The system will change the traffic lights to red whenever a person is present and sometimes when nobody is there
