A therapist runs a search and finds 500 articles on “stroke rehabilitation.” To narrow the results to those involving gait training, what is the best strategy?

Given the following points in a 2D space:   Point X Y A 2 3 B 5 6 C 3 3 D 8 8   Using k-Means clustering where k = 2, two clusters will be created (C1 and C2).  Use this table to answer the next 2 questions.

Assume you run hierarchical clustering on a dataset of 15 observations and obtain the following dendrogram. First, analyze the dendrogram above and identify the best 4-clusters solution. Clearly list below which points belong to each cluster (you can call the clusters C1, C2, C3 and C4).   C1 =  C2 = C3 = C4 =

What is the Jaccard’s distance between observation C and D?

When performing hierarchical clustering, which linkage method considers the maximum distance between points in two clusters?

Describe a real-world application in one or two sentences where association rule mining is useful:

Assume you run a clustering algorithm on a dataset that produces a clusters with 4 observations. In the table below, you find the 4 observations and the corresponding attributes. Compute the centroid for this cluster. You can round numbers to 2 decimals.    Observations Feature 1 Feature 2 Feature 3 A 23 15 34 B 14 9 32 C 41 10 36 D 42 10 22
