Data Mining - Proximity Measures for Numeric Attributes

Dik :

Jika dua benda diwakili oleh tupel (a, b, c, d, e) dan (f, g, h, i, j) :

-          a = X * 91

-          b = X * 92

-          c = X * 93

-          d = X * 94

-          e = X * 95

-          f = X * 80

-          g = X * 81

-          h = X * 82

-          i = X * 83

-          j = X * 84

X = two last digit in your student identity number

X = 15

h = 3 

Dit :

a. Jarak Euclidean antara dua benda = ?

b. Jarak Manhattan antara dua benda = ?

c. Jarak Minkowski antara dua benda = ?

d. Jarak Supremum antara dua benda = ? 

Penyelesaian:

-          a = 15 x 91 = 1365

-          b = 15 x 92 = 1380

-          c = 15 x 93 = 1395

-          d = 15 x 94 = 1410

-          e = 15 x 95 = 1425

-          f = 15 x 80 = 1200

-          g = 15 x 81 = 1215

-          h = 15 x 82 = 1230

-          i = 15 x 83 = 1245

-          j = 15 x 84 = 1260
