Continuing with k-means, we take a look at initial placement of centroids. Does it make a difference? How about how many of them there are in the beggining? Can k-Means get stuck on a solution? In this video, we leave the Interactive k-Means widget behind and introduce KMeans++ alongside our regular k-Means widget.
This video is a part of Introduction to Data Science video series that dives into machine learning, visual analytics, and joys of interactive data analysis using Orange Data Mining software (https://orangedatamining.com).
