Sklearn extra: KMedoids missing 'method' parameter

Asked 2021-Feb-24 at 12:13

According to the Sklearn_extra documentation on KMedoids, KMedoids should have the following parameters: n_clusters, metric, method, init, max_iter and random_state. The method parameter determines which algorithm to use: alternate or pam. According to sklearn_extra's user guide these methods are inherently different from each other. For my specific application I want to use the PAM version of K-medoids. However, the method parameter seems to have disappeared. When I run an inspect on the KMedoids function:

The euclidean distance function is working as expected, as it is calculating the distance between each item in the two arrays. In this regard, the euclidean distance matrix is symmetrical.

python kmedoids - calculating new medoid centers more efficiently

Asked 2020-Jan-13 at 17:05

I'm following an excellent medium article: https://towardsdatascience.com/k-medoids-clustering-on-iris-data-set-1931bf781e05 to implement kmedoids from scratch. There is a place in the code where each pixel's distance to the medoid centers is calculated and it is VERY slow. It has numpy.linalg.norm inside a loop. Is there a way to optimize this with numpy.linalg.norm or with numpy broadcasting or scipy.spatial.distance.cdist and np.argmin to do the same thing?

...

ANSWER

Answered 2020-Jan-13 at 17:05

There's a good chance numpy's broadcasting capabilities will help. Getting broadcasting to work in 3+ dimensions is a bit tricky, and I usually have to resort to a bit of trial and error to get the details right.

The use of linalg.norm here compounds things further, because my version of the code won't give identical results to linalg.norm for all inputs. But I believe it will give identical results for all relevant inputs in this case.

I've added some comments to the code to explain the thinking behind certain details.

ANSWER

Found the issues, indeed certainly related to the kMedoids() code which wasn't intended initially for Python 3.

To make it work for Python 3.5, edit the following lines related to the range() function as follows (cf. this related answer):
