我的第三次作业我的第三次作业
HW3
Part I: written assignment：
1. Cluster the following 8 points into three clusters:
A1(2,10), A2(2,5), A3(8,4), A4(5,8), A5(7,5), A6(6,4), A7(1,2), A8(4,9)
The distance function is Euclidean distance. Suppose initially we assign A1, A4, A7 as the center of each cluster, respectively. Use the K-Means algorithm to show only
The three cluster center after the first round execution
点A2到A1的距离为 5 ； 到A4为 ；到A7为；同理有下表
A1 A4 A7 A2 5 A3 5 A5 A6 A8
由上表可知第一轮后3个集为(1){A1} (2){A3,A4,A5,A6,A8} (3){A2,A7}
他们的中心是(1)(2,10) (2)(6,6) (3)(1.5,3.5)
(2)The final three clusters
第二轮
(2,10) (6,6) (1.5,3.5) A1 0 A2 5 A3 A4 A5 A6 2 A7 A8 第二轮后3个集为(1){A1,A8} (2){A3,A4,A5,A6}(3){A2,A7}
更新后 他们的中心是(1)(3,9.5) (2)(6.5,5.25) (3)(1.5,3.5)
第三轮
(3,9.5) (6.5,5.25) (1.5,3.5) A1 A2 A3 A4 A5 A6 A7 A8 第二轮后3个集为(1){A1,A8,A4} (2){A3,A5,A6}(3){A2,A7}
2. Perform AGNES clustering on the data set in Question 1. Show your results by drawing a dendrogram (树状图) (each step merges two clusters with the minimum distance). The dendrogram should clearly show the order in which the points are merged.
A1(2,10), A2(2,5), A3(8,4), A4(5,8), A5(7,5), A6(6,4), A7(1,2), A8(4,9)

Part II: Lab assignment
Production Recommendation
Using the “bank-estimation-data”, estimate the decision tree that predicts pep as a function of the other variables. Select “Expert” and set “pruning severity” at 75. Set the “Type” of pep as “Flag” and the “Direction” as “out”. Build decision trees using three options “Minimum records per child branch” values being (a) 56, (b) 15 and (c) 10, not selecting “use global pruning”.
Hand in: the confusion matrix for (a), (b) and (c) on the “val
