Proximity measure for mixed attributes

Webb3 feb. 2024 · 2. Manhattan Distance: This determines the absolute difference among the pair of the coordinates. Suppose we have two points P and Q to determine the distance between these points we simply have to calculate the perpendicular distance of the points from X-Axis and Y-Axis. In a plane with P at coordinate (x1, y1) and Q at (x2, y2).
