Web15 de fev. de 2024 · This is where standardization or Z-score normalization comes into the picture. Rather than using the minimum and maximum values, we use the mean and standard deviation from the data. By consequence, all our features will now have zero mean and unit variance, meaning that we can now compare the variances between the features.
