“Preference regression” is when we use special math to figure out what things people like more than others.
Imagine you have a bunch of toys, some are cars and some are dolls. You like cars more than dolls, and your friend likes dolls more than cars. Now imagine someone gives you a toy and asks if you like it more than all the other toys you have. You would compare the toy to all the other toys you have and then say if you like it more or less than the others.
Preference regression works the same way, but instead of toys, we use data like numbers or colors. We ask people to compare different data points and tell us which ones they like more. Then, we use math to figure out how much they like each data point compared to the others.
Just like how you and your friend have different preferences for toys, everyone has different preferences for things like data points. Preference regression helps us understand those preferences so we can make better decisions or predict what people might like in the future.
