Need of Normalization Decimal Scaling Method For Normalization Min-Max Normalization Z-Score Normalization Normalization is generally required when we are dealing with attributes on a different scale,otherwise,it may lead to a dilution in effectiveness of an important equally important attribute(on lower scale) because of other attribute having values on larger scale.In simple words,when multiple attributes are there but attributes have values on different scales,this may lead to poor data models while performing data mining operatiSee more on geeksforgeeksPublished Jun 13,2019What is Normalization in Data Mining and How to Do It Nov 23,2020·Normalization in data mining is a beneficial procedure as it allows achieving certain advantages as mentioned below It is a lot easier to apply data mining algorithms on a set of normalized data.The results of data mining algorithms applied to a set of normalized data are more accurate and results for this questionHow to normalize the data through the min-max normalization technique?How to normalize the data through the min-max normalization technique?How to normalize the data through the min-max normalization technique?
