Suppose that the data mining task is to cluster points (with (x, y) representing location) into three clusters, where the points are a1(2,10),a2(2,5),a3(8,4),b1(5,8),b2 (7,5),b3(6,4),c1(1,2),c2(4,9). the distance function is euclidean distance. suppose initially we assign a1, b1, and c1 as the center of each cluster, respectively. use the k-means algorithm to show only (a) the three cluster centers after the first round of execution. (b) the final three clusters.

What does 21 pilots middle aged name as a band 15 years prior to them naming their band 21 pilots?

Use a physical stopwatch to record the length of time it takes to run the program. calculate the difference obtained by calls to the method system.currenttimemillis() just before the start of the algorithm and just after the end of the algorithm. calculate the difference obtained by calls to the method system.currenttimemillis() at the start of the program and at the end of the program so that the elapsed time includes the display of the result. use the value returned by the method system.currenttimemillis() just after the end of the algorithm as the elapsed time.

The output voltage of a power supply is assumed to be normally distributed. sixteen observations are taken at random on voltage are as follows: 10.35, 9.30, 10.00, 9.96, 11.65, 12.00, 11.25, 9.58, 11.54, 9.95, 10.28, 8.37, 10.44, 9.25, 9.38, and 10.85
