The method you use to calculate the distance between data points will affect the end result. Euclidean Distance. The shortest distance between two points. For example, if x=(a,b) and y=(c,d), the Euclidean distance between x and y is √(a−c)²+(b−d)²
NettetIt's possible, but it isn't pretty. It requires (at a minimum) a small rewrite of AgglomerativeClustering.fit ( source ). The difficulty is that the method requires a number of imports, so it ends up getting a bit nasty looking.
