The Los Angeles SPI will use an extensive homicide database created by the FBI and LAPD called BIDMAS (Bureau of Investigation Document and Management Analysis System), which includes information from over 6,000 “Murder Books” from cases in Los Angeles from 1990 to 2010. The Los Angeles SPI will employ innovative machine learning techniques and advanced statistical methods to determine predictors of clearance and conviction rates for homicides and shootings and measure the degree to which predictors of gun homicide and shooting incidents are similar and different. Lastly, the SPI will create, test and evaluate an investigative tool based on deep learning algorithms and models. LAPD will aim to increase the solvability of homicides and shootings by determining the predictors of homicide clearances and convictions in Los Angeles, improve the prediction of case clearance and conviction for homicides by analyzing data from the Murder Books, and determine the impact of adopting the instrument/algorithm for predictors on clearance rates, conviction rates, and homicide rates.
