Part
III. Clustering countries by cultural dimensions
Perform
normalization of all numeric values. Remove attribute country name.
Perform
K-means (K=2) clustering of countries
by cultural dimensions.
Save
the output of clustering as Results2.arff. Copy data rows into data file clusterResults2.txt.
In
order to properly see 2 clusters of countries, use the code in ClusterAssignments.java. Add this file to a
new java project, and put Countries.csv and clusterResults2.txt into the project directory.
Part of Assignment 3. Run K-means algorithm on this dataset with K=3, and K=4. Generate the list of countries in each cluster for each
clustering. Which value of K (2, 3,
or 4) seems to produce the most meaningful clusters?
