NEW ALGORITHM PREDICTS WHEN AND WHERE A CRIME WILL HAPPEN BEFORE IT TAKES PLACE
HORIZONS
The AI model was tested across eight cities in the US and predicts future crimes with 80 to 90 per cent accuracy, without falling foul of bias
CRIME
YOUR ALGORITHM SUCCESSFULLY PREDICTED CRIME IN US CITIES A WEEK BEFORE THEY HAPPENED. HOW DID YOU BUILD THE ALGORITHM?
The city of Chicago and the seven other cities that we looked at have started putting out crime event logs in the public domain. In Chicago, these are actually updated daily with a week’s delay.
These event logs contain information about what happened, what type of crime it was, where it happened, the latitude, longitude, and a timestamp. In Chicago, we also have information about if there were any arrests made when there were interactions with the police officers.
So we start with this event log and then digitise the city into small areas of about two blocks by two blocks – about 1,000 feet [300 metres] across.
