A Better k-means++ Algorithm via Local Search
It is known that the optimal center of a given cluster is the average or mean of the cluster which is why the problem is also often called k-means clustering |
What is the alternative to k-means?
The first alternative method is called Gaussian mixture models (GMM) or sometimes expectation maximization (EM) clustering.
This form of clustering is quite similar to k-means.What is better than KMeans algorithm?
EM can be used to cluster data with more complex distributions, such as non-spherical clusters or clusters with mixed distributions.
EM is a more computationally expensive algorithm than K-means, but it can often lead to better clustering results.Which clustering algorithm is better?
k-means is the most widely-used centroid-based clustering algorithm.
Centroid-based algorithms are efficient but sensitive to initial conditions and outliers.
This course focuses on k-means because it is an efficient, effective, and simple clustering algorithm.
Figure 1: Example of centroid-based clustering.K-Means tends to work well when the data is well-separated and evenly distributed, while DBSCAN is better suited for datasets with irregular shapes or varying densities.
