detection

Detection is the process of identifying the presence of a specific object, signal, or condition within a certain environment or dataset. It involves analyzing data or stimuli to recognize patterns, features, or anomalies that indicate the existence of what is being looked for. For example, a security system detects intrusions, a medical test detects signs of disease, and a radar system detects aircraft. Detection is essential for decision-making and response, helping us identify when something noteworthy occurs so appropriate action can be taken.
