Data Normalization

Normalizing the data refers to scaling the data values to a much smaller range such as [-1, 1] or [0.0, 1.0]. There are different methods to normalize the data, as discussed below.

Consider that we have a numeric attribute A and we have n number of observed values for attribute A that are $V_1$, $V_2$, $V_3$, … $V_n$.

• Logarithmic transformation
• Root transformation
