sklearn.preprocessing.StandardScaler — scikit-learn 1.4.2 …
https://scikit-learn.org/stable/modules/generated/sklearn.preprocessing.StandardScaler.html
WEBclass sklearn.preprocessing.StandardScaler(*, copy=True, with_mean=True, with_std=True) [source] ¶. Standardize features by removing the mean and scaling to unit variance. The standard score of a sample x is calculated as: z = (x - u) / s. where u is the mean of the training samples or zero if with_mean=False , and s is the standard deviation ...

WEBNov 23, 2016 · Core of method. The main idea is to normalize/standardize i.e. μ = 0 and σ = 1 your features/variables/columns of X, individually, before applying any machine learning model. StandardScaler() will normalize the features i.e. each column of X, INDIVIDUALLY, so that each column/feature/variable will have μ = 0 and σ = 1.

Using StandardScaler() Function to Standardize Python Data
https://www.digitalocean.com/community/tutorials/standardscaler-function-in-python
WEBAug 3, 2022 · Standardization is a scaling technique wherein it makes the data scale-free by converting the statistical distribution of the data into the below format: mean - 0 (zero) standard deviation - 1. Standardization. By this, the entire data set scales with a zero mean and unit variance, altogether.

WEBStandardization, or mean removal and variance scaling ¶. Standardization of datasets is a common requirement for many machine learning estimators implemented in scikit-learn; they might behave badly if the individual features do not more or less look like standard normally distributed data: Gaussian with zero mean and unit variance.

WEBMar 4, 2019 · Use StandardScaler if you want each feature to have zero-mean, unit standard-deviation. If you want more normally distributed data, and are okay with transforming your data. Check out scikit-learn’s QuantileTransformer(output_distribution='normal'). Use MinMaxScaler if you want to have a light touch. It’s non-distorting.
