We will discuss different data normalisation methods such as value mapping normalisation, discretization normalisation, equal width discretization , egual frequency discretization and aggregation normalisation
Data Transformation | Normalisation techniques In the part 1 of the series we looked at the various methods of normalising the data including min-max and box-cox transformations. In this part we look at the following Value Mapping Discretization Equal Width Discretization Equal Frequency Discretization Aggregation Value Mapping Sometimes in the...
The process of normalisation entails converting numerical values into a new range using a mathematical function. Two common normalisation methods are min-max normalisation and z score normalisation
Data Transformation | Normalisation Techniques Almost always when we get raw data in any project, it is unfit for direct consumption for analysis or modelling . It is a especially a concern when the data volume is huge for example in a big data analytics project . In this blog...
