and their historical data was used to train Series Finder to detect housebreak patterns. The algorithm tries to construct a modus operandi (MO). The M.O. is a set of habits of a criminal and is a type of behavior used to characterize a pattern. The data of the burglaries include means of entry (front door, window, etc.), day of the week, characteristics of the property (apartment, house), and geographic proximity to other break-ins. Using nine known crime series of burglaries, Series Finder recovered most of the crimes within these patterns and also identified nine additional crimes. Machine learning is a tremendous tool for predictive policing. If patterns are identified the police can immediately try to stop them. Without such tools it can take weeks and even years of shifting though databases to discover a pattern. Series Finder provides an important data-driven approach to a very difficult problem in predictive policing. It’s the first mathematically principled approach to the automated learning of crime series. Sociodemographics, along with spatial and temporal information, are all aspects that crime analysts look at to understand what is going on in their jurisdiction. Crime analysis employs data mining, crime mapping, statistics, research methods, desktop publishing, charting, presentation skills, critical thinking, and a solid understanding of criminal behavior. In this sense, a crime analyst serves as a combination of an information systems specialist, a statistician, a researcher, a criminologist, a journalist, and a planner for a local police department. Profession Crime analysts are employed at all levels of law enforcement, often as civilian professionals while other agencies appoint sworn police officers to a crime analysis position. In the United States, most crime analysts are employed by municipal or county police departments. In countries other than the United States, crime analysis is often called "intelligence analysis" or "criminal intelligence analysis," but in the U.S., this term is generally understood to apply to a different law enforcement discipline. Many medium and large local law enforcement agencies have dedicated crime analysis units, while many smaller jurisdictions (e.g. townships) may have a police force that consists of just a few police officers who do not specialize in crime analysis or any other specific aspect of law enforcement. As a profession, crime analysis has existed since at least the 1960s (though some of its most essential functions were probably performed even in ancient times). The earliest known reference is in O.W. Wilson's
