A defect in a piece of raw steel being fed into a computer numerical control (CNC) machine is an example of a point anomaly. • Contextual anomalies (also referred to as conditional outliers): These are similar to point anomalies except they are usually only cause for concern within a specific context. For example, the dimensions for a piece of steel will fluctuate slightly based on ambient temperature; a measurement that may app
