Then, we calculate our n value or total number of pixels: num_of_pixels = len (train_set) * 28 * 28. Note that the 28 ∗ 28 is the height and width of the images inside our dataset. Now, we sum the pixels values by iterating over each batch, and we calculate the mean by dividing this sum by the total number of pixels.

Sep 24, 2021 · The data can be normalized by subtracting the mean (µ) of each feature and a division by the standard deviation (σ). This way, each feature has a mean of 0 and a standard deviation of 1. This results in faster convergence. In machine vision, each image channel is normalized this way.

Nov 25, 2019 · Z-score is fine. However, min_max_norm = (data - data.min())/(data.max() - data.min()) For normalisation, the values are squashed in [0, 1]. If you have an outlier say data.max() the transformed values will be very small for min_max_norm(max in denominator) for the majority of samples. Thereby affecting the statistics of your transformed distribution.
