Gini Index

The Gini index, a measure of inequality, is increasingly used in diverse fields beyond economics, including reinforcement learning and fairness-aware algorithms. Current research focuses on adapting and extending the Gini index for applications like resource allocation (e.g., in public health), risk-averse decision-making in reinforcement learning, and promoting fairness in ranking systems, often employing novel algorithms to optimize generalized Gini indices or address computational challenges. This expanding application highlights the Gini index's value as a versatile tool for quantifying inequality and guiding the design of more equitable and efficient systems.
