Description: Niche bias refers to a type of bias that occurs when artificial intelligence (AI) systems are trained using data from a specific subset of the population. This can lead to AI models generating results that are unfair or inaccurate for groups that are not adequately represented in the training data. This phenomenon is particularly concerning in AI applications that impact critical decisions, such as hiring, lending, or criminal justice. Niche bias can manifest in various ways, including the underrepresentation of ethnic minorities, genders, or socioeconomic groups in the data, resulting in poor model performance for these groups. The lack of diversity in the data can lead AI systems to perpetuate stereotypes or discriminate against certain groups, raising serious ethical questions about fairness and justice in the use of technology. Therefore, it is essential for AI developers to be aware of this bias and actively work to mitigate its effects, ensuring that models are trained with more representative and diverse datasets.
