If I have a feature with replicated values but each of these values indicates a different piece of information.
example: feature 'street name' with value 'A' which some of these 'A's are for Boston city and the others for New York City.
In this case, should I change the street name values which indicate NYC to something like 'A_NYC'? I assume that if I kept the 'A' values with no change then there will be a relation between Boston's 'A' and NYC and built a correlation between unrelated features.
I hope I made my point clear and sorry if this question was answered previously and I didn't notice.
