K means clustering pandas
WebJan 30, 2024 · The very first step of the algorithm is to take every data point as a separate cluster. If there are N data points, the number of clusters will be N. The next step of this algorithm is to take the two closest data points or clusters and merge them to form a bigger cluster. The total number of clusters becomes N-1.

WebK-means clustering performs best on data that are spherical. Spherical data are data that group in space in close proximity to each other either. This can be visualized in 2 or 3 dimensional space more easily. Data that aren’t spherical or should not be spherical do not work well with k-means clustering.
