Homework Assignment 2

In K-means clustering, a challenge is determining the appropriate k value for clustering the data. One technique for determining k is called the elbow method. Investigate the elbow method, then use it with MNIST digits and Iris datasets to determine whether this technique yields the correct number of classes for each dataset.

1. Use the agglomerative clustering algorithm in Scikit-Learn to cluster the handwritten digits in the load digits dataset.

2. Use the K-Means clustering algorithm in Scikit-Learn to cluster the handwritten digits in the load digits dataset.

3. Compare the accuracy of the two algorithms.

4. Use PCA to transform the load digits data into 2 dimensions, and plot the data
