Topic: Unsupervised Techniques

You wish to examine the results of k$-$means clustering from a data set containing four attributes: a$1,$ a$2,$ a$3,$ and a$4.$ The resulting scatterplot is as follows:

From this scatterplot, you can infer that $($Select one$)$

A$.$

attributes a$2$ and a$4$ partition the data set well between cluster$\_0$ and cluster$\_1.$

B$.$

attributes a$1$ and a$3$ do not partition the data set well between cluster$\_0$ and cluster$\_1.$

C$.$

attributes a$2$ and a$4$ partition the data set well between cluster$\_0$ and cluster$\_2.$

D$.$

attributes a$2$ and a$4$ do not partition the data set between cluster$\_0$ and cluster$\_2$
