Feature Scaling: Quick Introduction and Examples using Scikit-learn  26 Sep 2017    data-science python data-preprocessing
Feature Scaling techniques (rescaling, standardization, mean normalization, etc) are useful for all sorts of machine learning approaches and *critical* for things like k-NN, neural networks and anything that uses SGD (stochastic gradient descent), not to mention text processing systems. Included examples: rescaling, standardization, scaling to unit length, using scikit-learn. Read More ›
