Outlier

Values distant from most other values. In machine learning, any of the following are outliers: • Weights with high absolute values • Predicted values relatively far away from the actual values • Input data whose values are more than roughly 3 standard deviations from the mean Outliers often cause problems in model training. Clipping is one way of managing outliers

An outlier is a data value that lies in the tail of the statistical distribution of a set of data values.
