What is Normalization?
Normalization allows us to weight the scores depending on how many traits exist in a category.
Example: A collection of 8000 NFTs has a Face Color category with 4 face colours and a Hair Color category with 20 hair colours.
Within the faces, there is an even split of 2000 NFTs in each color. In the Hair color, Black hair appears 2000 times in the collection and the other colors each show 300 times.
Without normalizatiom, the score for getting black hair in your NFT would be the same as for getting red skin: Normalization adjusts this to allow for the fact that within the hair category the chance of getting black hair is a lot higher than the chance of getting red skin is in the skin category.
