In addition, discretization also acts as a variable (feature) selection method that can significantly impact the performance of classification algorithms used in the analysis of high-dimensional biomedical data.
Discretization is the process of putting values into buckets so that there are a limited number of possible states.

1 - About Discretization is the process of transforming numeric variables into nominal variables called bin.
Discretization is a process that transforms quantitative data into qualitative data. Discretization methods include manual methods, for example visual distribution analysis.

So, important effects of discretization among which smooth things of data, reducing noise, reducing data size and also enable specific methods down stream to analyze the data using nominal data type.

– Discretization is considered a data reduction mechanism because it diminishes data from a large domain of numeric values to a subset of categorical values.

You can imagine this is most for small data sets.
If your data mining solution uses relational data, you can control the number of buckets to use for grouping … Discretization is also concerned with the transformation of continuous differential equations into discrete difference equations, suitable for numerical computing..

"Discretization for Data Mining."
The created variables are nominal but are ordered (which is a concept that you will not find in true nominal variable) and algorithms can exploit this ordering information. "Discretization for Data Mining.".
Data Binarization in data mining is used to transform both the discrete and continuous attributes into binary attributes. Data Discretization in data mining is the process that is used to transform the continuous attributes. There are several methods that you can use to discretize data.
