K means clustering solved problems
WebIn this problem, you will generate simulated data, and then perform \( K \)-means clustering on the data. (a) Generate a simulated data set with 20 observations in each of \( \mathbf{K}=\mathbf{5} \) well-separated clusters, with \( p=2 \) variables describing each observation. Do it in similar fashion to \( K=3 \) case in " \( K \)-means ... Web1) Set k to the desired value (e.g., k=2, k=3, k=5). 2) Run the k-means algorithm as described above. 3) Evaluate the quality of the resulting clustering (e.g., using a metric such as the within-cluster sum of squares). 4) Repeat steps 1-3 for each desired value of k. The choice of the optimal value of k depends on the specific dataset and the ...
