Question

The K-Means algorithm has some limitations. For example, it makes hard assignments (A point either completely belongs to a cluster or not belongs at all) of points to clusters.

Note: Soft assignment can be considered as the probability of being assigned to each cluster: say K = 3 and for some point xn, p1 = 0.7, p2 = 0.2, p3 = 0.1)

Which of the following algorithm(s) allows soft assignments?

Gaussian mixture models

Fuzzy K-means

Select the correct answer from below options:

A. 1 only

B. 2 only

C. 1 and 2

D. None of these

Answer 1

Answer: (C)

Both, Gaussian mixture models and Fuzzy K-means allow soft assignments.
