machine learning
Machine learning (ML) is a field of study in artificial intelligence concerned with the development and study of Computational statistics, statistical algorithms that can learn from data and generalise to unseen data, and thus perform Task ( ...
, normalization is a statistical technique with various applications. There are two main forms of normalization, namely ''data normalization'' and ''activation normalization''. Data normalization (or
feature scaling) includes methods that rescale input data so that the

* Feature recognition, could be a hole, pocket, or notch
* Feature (computer vision), could be an edge, corner or blob

min-max normalization, where each feature is transformed to have the same range (typically
