The bounds are valid with high probability and, up to logarithmic factors, scale as the square root of the effective sample size.
Webb29 dec. 2024 · Normalization can be achieved by Min-Max Scaler. By default, Min-Max Scaler scales features between 0 and 1. We can also choose to specify the min and the max values using the “feature_range” argument in python. The formula for Min-Max Scaler is: It is important to note that, normalization is sensitive to outliers.
