k means clustering multiple variables python
What is multi variable k-means clustering?
The Multivariate Clustering tool uses the K Means algorithm by default.
The goal of the K Means algorithm is to partition features so the differences among the features in a cluster, over all clusters, are minimized.
Because the algorithm is NP-hard, a greedy heuristic is employed to cluster features.How does clustering work for multiple features?
The Multivariate Clustering tool utilizes unsupervised machine learning methods to determine natural clusters in your data.
These classification methods are considered unsupervised as they do not require a set of preclassified features to guide or train the method to find the clusters in your data.Can you use k-means clustering on multiple variables?
You might have come across k-means clustering for 2 variables and as a result, plotting a 2-dimensional plot for it is easy.
Imagine, you had to cluster data points taking into consideration, 3 variables/features of a data set instead of 2.
Things get interesting here15 sept. 2021While variable choice remains a debated topic, the consensus in the field recommends clustering on as many variables as possible, as long as the set fits this description, and the variables that do not describe much of the variance in Euclidean distances between observations will contribute less to cluster assignment.
