How to normalize array in Numpy?

May 4, 2021February 17, 2025Pythoneo

Let’s learn about how to normalize an array in Numpy Python library. We will use linalg norm function for that purpose. Normalization scales numerical data to a standard range, often between 0 and 1 or to have a unit norm. This process is essential for algorithms sensitive to the scale of input features, such as Continue reading
