Canberra Distance

<Previous | Next | Content>

Canberra distance examines the sum of series of a fraction differences between coordinates of a pair of objects. Each term of fraction difference has value between 0 and 1. If one of coordinate is zero, the term become unity regardless the other value, thus the distance will not be affected. Note that if both coordinate are zeros, we need to be defined as . This distance is very sensitive to a small change when both coordinate near to zero.

Formula

For example:

Point A has coordinate (0, 3, 4, 5) and point B has coordinate (7, 6, 3, -1).

The Canberra Distance between point A and B is
