Standardization vs normalization

For example, some data mining techniques use the Euclidean distance Therefore, all parameters should have the same scale for a fair comparison between them Two methods are usually well known for rescaling data Normalization, which scales all numeric variables in the range [0,1] One possible formula ,Data Mining Business Intelligence Statistical Analysis Predictive Analytics Text Analytics Data Mining Data Mining is the analysis of large quantities of data to extract previously unknown, interesting patterns of data, unusual data and the dependenci Note that the goal is the.
