An Automated Decision System is software that uses algorithms, often powered by artificial intelligence and large datasets, to make or support decisions without direct human intervention. These systems are commonly used in areas like hiring, credit scoring, fraud detection, and content moderation. They analyze input data, apply programmed rules or learned patterns, and produce outcomes such as rankings, approvals, or recommendations. While they can improve efficiency and consistency, concerns exist about transparency, fairness, and accountability in their decision-making processes.
