Machine learning (ML) is a field of computer science that provides computer systems with the ability to learn from historical data, without being explicitly programmed. Machine learning algorithms look for patterns in data and construct mathematical models that will assist in making predictions on the future data. Nowadays, predictive models are increasingly being used to make decisions for people and about people. Use of such models in making decision about individuals has raised concerns about their potential unfairness toward certain groups. Even though effectiveness of PRM has been proven in many fields (i.e. Insurance, Finance, Health), it has only lately been applied to the classification of risk in Child Protective Services (CPS). The main concern, when using predictive modelling in child welfare setting is predictive bias. If the predictive risk models are developed based on biased data to produce a risk score for a child, then this can aggravate the original bias. To improve decision making in the child welfare domain with the help of predictive risk models, it’s vital to ensure the model is fair and discrimination-free. The main objective of Sahar’s research is to create a fair algorithm and further to develop a non-discriminatory predictive risk model.
