Usable Data

The Luminosity team possesses vast knowledge and expertise in transforming raw justice system data. We extract, cleanse, conduct quality assurance checks, and validate each data source. Next, we employ sophisticated methodologies to standardize, transform, and link data from siloed software systems. Our team has successfully integrated justice system siloed data (e.g., law enforcement, jail, courts, prosecutor, pretrial services) and used these data to conduct many of the largest pretrial justice related research projects in the country, each involving more than a million cases. Our research includes evaluating New Jersey’s criminal justice reform, identifying the strongest predictors of pretrial outcomes, and assessing the use of alternatives to detention in the federal court. Our team is highly skilled in creating usable justice system data to leverage data analytics and achieve actionable insights.

Data Analytics

Luminosity’s team of business analysts, data scientists, data analysts, and information technology experts collaborates with cities and states to apply data analytics to achieve their objectives. We have partnered with communities to increase operational transparency; reduce racial and ethnic disparities; responsibly lower jail populations; and identify, implement, and monitor justice system reforms. We use descriptive analytics to identify what has happened and diagnostic analytics to determine why it has happened. Supervised and unsupervised machine learning techniques (e.g., random forest, regression, support vector machines) are used to identify trends and predict outcomes (predictive analytics). We then combine the analytical results with simulation to recommend a course of action and propose the best strategies for our clients to achieve their desired outcomes.

Actionable Insights

Data needs to be more than useable, it must be accessible, interpretable, and provide insights that can be acted upon. At Luminosity, we’ve developed a model for generating key performance metrics to monitor and evaluate pretrial justice systems. This model (SAVANT – JUSTICE SYSTEM DATA FUSION™) has been successfully tested on data from counties in North Carolina, Wisconsin, and Ohio. Our team is currently partnering with several cities across the country to apply SAVANT to generate research, performance, and outcome measures. These measures are utilized to feed strategic, operational, and analytical dashboards to monitor and evaluate the impact of justice system reforms. Our Data Analytics team employs SAVANT to illuminate actionable insights and empower our clients to make strategic, data driven decisions.

WHAT DO YOU DO?

03/25/2021

Simple question, still challenging to answer after all these years.  Not because we don’t know what we do – our mission is to advance pretrial justice in America and we believe our partnerships with communities across the country do just that.  But what does that look like?  To us it looks like reforming justice systems to be more ‘just’ – it means safer communities, reduced racial and ethnic disparities, and a less costly and more fair system.  But when people ask “what do you do?”, they really want to know “how do you do it?”.  That question is harder to answer because the way we achieve our mission has changed over time.
