Gregory Kirk Ridgeway (born 1973) is professor of criminology and statistics at the University of Pennsylvania, where he is also chair of the Department of Criminology.

Education

Ridgeway received his B.S. from California Polytechnic State University in 1995 and his M.S. and Ph.D. from the University of Washington in 1997 and 1999, respectively. All three of his degrees are in statistics. [1] His Ph.D. thesis was entitled "Generalization of boosting algorithms and applications of Bayesian inference for massive datasets". [2]

Career

Early in his career, Ridgeway worked at the RAND Corporation, where he served as the director of the Safety and Justice Program from 2009 to 2012, and of the Center for Quality Policing from 2008 to 2012. He later served as the acting director of the National Institute of Justice for 19 months before joining the University of Pennsylvania in August 2014. [1] [3] [4] In January 2021, he was named the co-editor-in-chief of the Journal of Quantitative Criminology . [5]

Research

Ridgeway's research focuses on using statistical techniques to examine aspects of the United States' criminal justice system. These aspects include, but are not limited to, stop-and-frisk in New York City, which, in a 2007 study, he found was racially biased, with blacks and Hispanics being more likely to be frisked, searched, or arrested once stopped (though they were no more likely to be stopped than whites). [6] [7]

Honors and awards

Ridgeway is a fellow of the American Statistical Association. [1]

Terry v. Ohio, 392 U.S. 1 (1968), was a landmark decision of the Supreme Court of the United States in which the Court ruled that it is not unconstitutional for American police to "stop and frisk" a person they reasonably suspect to be armed and involved in a crime. Specifically, the decision held that it is not a violation of the Fourth Amendment to the U.S. Constitution's prohibition on unreasonable searches and seizures when a police officer stops a suspect on the street and questions him or her even without probable cause to arrest, so long as the police officer has a reasonable suspicion that the person has committed, is committing, or is about to commit a crime. The Court also ruled that the police officer may perform a quick surface search of the person's outer clothing for weapons if they have reasonable suspicion that the person stopped is "armed and presently dangerous". This reasonable suspicion must be based on "specific and articulable facts", and not merely upon an officer's hunch.

A Terry stop in the United States allows the police to briefly detain a person based on reasonable suspicion of involvement in criminal activity. Reasonable suspicion is a lower standard than probable cause which is needed for arrest. When police stop and search a pedestrian, this is commonly known as a stop and frisk. When police stop an automobile, this is known as a traffic stop. If the police stop a motor vehicle on minor infringements in order to investigate other suspected criminal activity, this is known as a pretextual stop. Additional rules apply to stops that occur on a bus.

Frisking is a search of a person's outer clothing wherein a person runs their hands along the outer garments of another to detect any concealed weapons or objects.

Race in the United States criminal justice system

Race in the United States criminal justice system refers to the unique experiences and disparities in the United States in regard to the policing and prosecuting of various races. There have been different outcomes for different racial groups in convicting and sentencing felons in the United States criminal justice system. Experts and analysts have debated the relative importance of different factors that have led to these disparities.

Ensemble learning

In statistics and machine learning, ensemble methods use multiple learning algorithms to obtain better predictive performance than could be obtained from any of the constituent learning algorithms alone. Unlike a statistical ensemble in statistical mechanics, which is usually infinite, a machine learning ensemble consists of only a concrete finite set of alternative models, but typically allows for much more flexible structure to exist among those alternatives.

Criminal stereotype of African Americans Ethnic stereotype

The criminal stereotype of African Americans in the United States is an ethnic stereotype according to which African Americans, and African American males in particular, are dangerous criminals. The origin of this stereotype is that as a demographic they are proportionally over-represented in the numbers of those that are arrested for committing crimes: for example, according to official FBI statistics, in 2015 51.1% of people arrested for homicide were African American, even though African American people account only for 13.4% of the total United States population. The figure of the African-American man as a criminal has appeared frequently in American popular culture, further reinforcing this image in the collective unconscious.

The relationship between race and crime in the United Kingdom is the subject of academic studies, government surveys, media coverage, and public concern. Under the Criminal Justice Act 1991, section 95, the government collects annual statistics based on race and crime.

The stop-question-and-frisk program, or stop-and-frisk, in New York City, is a New York City Police Department practice of temporarily detaining, questioning, and at times searching civilians and suspects on the street for weapons and other contraband. This is what is known in other places in the United States as the Terry stop. The rules for the policy are contained in the state's criminal procedure law section 140.50 and based on the decision of the US Supreme Court in the case of Terry v. Ohio.

Predictive policing refers to the usage of mathematical, predictive analytics, and other analytical techniques in law enforcement to identify potential criminal activity. Predictive policing methods fall into four general categories: methods for predicting crimes, methods for predicting offenders, methods for predicting perpetrators' identities, and methods for predicting victims of crime.

Criminal justice reform in the United States

Criminal justice reform addresses structural issues in criminal justice systems such as racial profiling, police brutality, overcriminalization, mass incarceration, and recidivism. Reforms can take place at any point where the criminal justice system intervenes in citizens’ lives, including lawmaking, policing, sentencing and incarceration. Criminal justice reform can also address the collateral consequences of conviction, including disenfranchisement or lack of access to housing or employment, that may restrict the rights of individuals with criminal records.

Outline of machine learning Overview of and topical guide to machine learning

The following outline is provided as an overview of and topical guide to machine learning. Machine learning is a subfield of soft computing within computer science that evolved from the study of pattern recognition and computational learning theory in artificial intelligence. In 1959, Arthur Samuel defined machine learning as a "field of study that gives computers the ability to learn without being explicitly programmed". Machine learning explores the study and construction of algorithms that can learn from and make predictions on data. Such algorithms operate by building a model from an example training set of input observations in order to make data-driven predictions or decisions expressed as outputs, rather than following strictly static program instructions.

In the United States, use of deadly force by police has been a high-profile and contentious issue. In 2019, 1,004 people were killed by police shootings according to The Washington Post and 1,098 people were killed by police in total according to the "Mapping Police Violence" project.
