WebThe formula for Z-score normalization is below: \frac {value - \mu} {\sigma} σvalue−μ Here, μ is the mean value of the feature and σ is the standard deviation of the feature. If a value is exactly equal to the mean of all the values of the feature, it will be normalized to 0. WebIn such situations, database recovery procedures in DBMS are employed to retrieve the data.
