WebJun 9, 2016 · so i have 2 approaches: standardize all the data with min_max scaling, now all the numeric data are between [0,1] now we can use euclidean distance alone calculate the euclidean distance for numeric data and calculate hamming distance for categorical data, and then combine both distances (with weights) my question is: WebFeb 25, 2024 · Hamming Distance measures the similarity between two strings of the same length. The Hamming Distance between two strings of the same length is the number of positions at which the corresponding characters are different. Let’s understand the concept using an example. Let’s say we have two strings: “euclidean” and “manhattan”
