Do you think it would be acceptable for a fire department to ignore an emergency call because some AI algorithm tells them it's 92% likely to be false? Who would be responsible if the algorithm made a mistake and people died?
Not necessarily what OP is proposing. It could be a group if people fielding calls to the department who rapidly investigate all calls, and get the fire department there for real fires.
They could also provide some first responder care... maybe this is already what some fire departments do?
To investigate whether a fire call is real, wouldn't you need to be a trained firefighter? For example, you may have to enter a building that's possibly on fire to see if there's a fire. And a small fire isn't necessarily obvious by just looking at the building from the outside.
Also, if someone has to investigate before the fire department was dispatched, you'd lose a lot of valuable time, allowing the fire to spread. It could be a win if there was no fire, but a huge loss (burned buildings, dead people) if there actually was a fire.
Yeah I was playing devils advocate I guess, I do agree with you. The best equipped people to investigate the false alarms is probably the fire department itself, and they are already the ones doing the investigating.
