3.4 Data Scaling, Normalization, and Transformation Techniques

The scale and distribution of your dataset can profoundly influence the effectiveness of numerous models, especially those that heavily rely on distance calculations or employ gradient-based optimization techniques.

Many machine learning algorithms operate under the assumption that all features exist on a uniform scale, which can potentially lead to skewed models if features with broader ranges overshadow those with narrower ranges. To mitigate these challenges and ensure optimal model performance, data scientists employ a variety of data preprocessing techniques, including scaling, normalization, and other transformative methods.

This section delves into an array of techniques utilized ...
