Issue kmeans code.

[Vincent-Vercruyssen]

In file: try_kmeans.ipynb

In function: find_closest()

Here you have to update the min_dist parameter in the IF-condition.

[Behrouz-Babaki]

I updated the find_closest function to this:

def find_closest(point , centers):
    min_dist = distance(point, centers[0])
    center = 0
    for i in range(1,len(centers)):
        dist = distance(point, centers[i])
        if dist < min_dist:
            min_dist = dist
            center = i
    return center
