Feature scaling is a method used to normalize the range of independent variables or features of data. In data processing , it is also known as data normalization and is generally performed during the data preprocessing step.
The dataset consists of PCA transformed features (from V1, to V28) well as the Time (time elapsed since the initial transaction) and Amount (transaction value). We processed the dataset using the steps: Scaling : The Time and Amount features by utilizing StandardScaler to standardize their input range. [7]
Feature scaling, a method used to standardize the range of independent variables or features of data; Image scaling, the resizing of an image; Multidimensional scaling, a means of visualizing the level of similarity of individual cases of a dataset
Robust measures of scale can be used as estimators of properties of the population, either for parameter estimation or as estimators of their own expected value.. For example, robust estimators of scale are used to estimate the population standard deviation, generally by multiplying by a scale factor to make it an unbiased consistent estimator; see scale parameter: estimation.

Relief is an algorithm developed by Kira and Rendell in 1992 that takes a filter-method approach to feature selection that is notably sensitive to feature interactions. [1] [2] It was originally designed for application to binary classification problems with discrete or numerical features.
