Denormalization
Denormalization is the process of reversing normalization in a database. In the denormalization main we integrate these functions:
denormalizationStanddenormalizationLogdenormalizationCOSdenormalizationDividedenormalizationMinMaxAndPercentile
Hyper-parameters
The denormalization process takes the hyperParameters from the normalization process that was triggered before.
