DATA MINING 5

 Jika dua benda diwakili oleh tupel (a, b, c, d, e) dan (f, g, h, i, j):
- Hitung jarak Euclidean antara dua benda.
- Hitung jarak Manhattan antara dua benda.
- Hitung jarak Minkowski antara dua benda, menggunakan h = 3.
- Hitung jarak supremum antara dua benda.

o  a = X * 91

o  b = X * 92

o  c = X * 93

o  d = X * 94

o  e = X * 95

o  f = X * 80

o  g = X * 81

o  h = X * 82

o  i = X * 83

o  j = X * 84

X = two last digit in your student identity number

 Penyelesaian:

Jika X=23 , maka :

·         a = 23 x 91 = 2093

·         b = 23 x 92 = 2116

·         c = 23 x 93 = 2139

·         d = 23 x 94 = 2162

·         e = 23 x 95 = 2185

·         f = 23 x 80 = 1840

·         g = 23 x 81 = 1863

·         h = 23 x 82 = 1886

·         i = 23 x 83 = 1909

·         j = 23 x 84 = 1932

Objek    y    =  ( a, b, c, d, e )

                   =  (2093 , 2116,2139,2162,2185)

Objek    z    =  ( f, g, h, i, j )

                    =   ( 1840 , 1863, 1886, 1909, 1932)
