collaborative filtering approach code example
Example: collaborative filtering algorithm
>>> from scipy import spatial
>>> a = [1, 2]
>>> b = [2, 4]
>>> c = [2.5, 4]
>>> d = [4.5, 5]
>>> spatial.distance.euclidean(c, a)
2.5
>>> spatial.distance.euclidean(c, b)
0.5
>>> spatial.distance.euclidean(c, d)
