Description: Representation bias refers to a type of bias that occurs when certain groups are underrepresented or misrepresented in the training data used to develop artificial intelligence (AI) models. This phenomenon can lead AI systems to produce results that do not adequately reflect the diversity of the population, resulting in unfair or discriminatory decisions. Inadequate representation can arise from various sources, such as data selection, lack of diversity in development teams, or the perpetuation of existing stereotypes. This bias is particularly concerning in critical applications, such as facial recognition, hiring processes, and criminal justice systems, where automated decisions can significantly impact people’s lives. Ethics in AI demands that representation bias be addressed to ensure that systems are fair, equitable, and accountable. Identifying and mitigating this bias is essential for building technologies that serve the entire society, avoiding the exclusion and marginalization of historically disadvantaged groups.
