Consider the following eight examples: A1 = (4,20), A2 = (4,10), A3 = (16,8), A4 = (10,16), A5 = (14,10), A6 = (12,8), A7 = (2,4), A8 = (8,18) The distance function is Euclidian distance. Use single-link, complete-link agglomerative clustering, and centroid techniques to cluster these examples. Show your calculations and draw the dendrograms for each technique.

For each of the following sequences find a functionansuch that the sequence is a1, a2, a3, . . .. You're looking for a closed form - in particular, your answer may NOT be a recurrence (it may not involveany otherai). Also, while in general it is acceptable to use a "by cases"/piecewise definition, for this task you must instead present a SINGLE function that works for all cases.(Hint: you may find it helpful to first look at the sequence of...
