1. A predictive policing system comprising:
at least one crime prediction processing device constructed to carry out a set of one or more instructions to:
receive at least one historical crime report including a set of historical crime data corresponding to a plurality of criminal events, the crime data including a crime location, a crime time, a crime date, and a crime type associated with each criminal event;determine a spatial domain based on a set of selected crime locations received as part of the crime data;subdivide the spatial domain into a plurality of discrete geographic regions;process the crime data with an epidemic type aftershock sequence point process crime forecasting algorithm using a parametric equation including an iterative Expectation-Maximization formula taking into account spontaneous events and triggered events to produce a set of one or more discretized probabilities for a particular crime type;rank the set of discretized probabilities in accordance with a display threshold criteria;for one or more discretized probabilities, output a predictive crime forecast assigning a discrete geographic region to at least one crime type; andcombine the predictive crime forecast with a visual map element depicting the geographic regions with at least one discretized probability meeting the display threshold criteria to create a predictive crime report having at least one geographic region with a probability of a future crime occurrence at a particular time interval associated with at least one crime type. |
