Tambe's systems provided measurable outcomes that prove A.I. can be more efficient in managing patrol schedules than a lone human decision-maker. After LAX security officials implemented Tambe's first software system, called ARMOR, they saw an immediate, five-fold increase in the seizure of weapons, drugs and more. In 2013, a study by Los Angeles Metro found a 66 percent increase in the number of fare jumpers on L.A.'s subways. ARMOR was even adapted for the U.S. Coast Guard to catch illegal fishers in the Gulf of Mexico. ARMOR-FISH, tested in 2014, located illegal activities, though funding for the project has since stalled.
