C4.5
– weka.classifiers.j48.J48
K-means
– weka.clusterers.SimpleKMeans
Try using reduced error pruning for the C4.5. Did it change the produced model? Why?
For K-means, for the first run, set k=10. Adjust as needed. What was the final number of k? Why?
Linear regression

M5′

Regression Tree

K-means clustering
– weka.clusterers.SimpleKMeans
A) How many leaves did the Model tree produce? Regression Tree? What happens if you change the pruning factor?
How many clusters did you choose for the K-means method? Was that a good choice? Did you try a different value for k?
B) Now perform the same analysis on the bodyfat.arff data set.
