Fault detection

Definition

Fault detection refers to the process of identifying anomalies or faults within a system to ensure proper operation and prevent failures. It is essential for maintaining system reliability and performance, often utilizing various monitoring techniques to detect irregularities before they escalate into serious issues. In industrial automation and machine learning contexts, fault detection plays a crucial role in predictive maintenance and enhancing system efficiency.
