K-Means is a widely-used clustering algorithm in Machine Learning, boasting numerous benefits but also presenting significant challenges. In this article, we delve into its limitations and offer straightforward solutions to address them.

K-Means is a clustering algorithm that partitions data into K clusters. It initializes K centroids randomly and then assigns each data point to the nearest centroid. Centroids are recalculated based on the mean of assigned points, and the process repeats until convergence.

I illustrate it below with t-distributed stochastic neighbor embedding, a dimension reduction technique. Each cluster is represented by a color.
