Pareto scaling是什么

WebNational Center for Biotechnology Information In multi-objective optimization, the Pareto front (also called Pareto frontier or Pareto curve) is the set of all Pareto efficient solutions. The concept is widely used in engineering. It allows the designer to restrict attention to the set of efficient choices, and to make tradeoffs within this set, rather than considering the full range of every parameter.

WebDescription. The function provides a data pretreatment approach called Pareto Scaling. Each column of the table is given a mean of zero by substracting the column column mean from each value in the column; then each value in each column is divided by a scaling factor, represented by the square root of the standard deviation of the column values.
