22. Cluster Analysis
Cluster analysis or clustering is the
assignment of a set of observations into
subsets (called clusters) so that observations
in the same cluster are similar in some
sense. Clustering is a method of
unsupervised learning, and a common
technique for statistical data analysis used in
many fields, including machine learning, data
mining, pattern recognition, image analysis
23. Cluster Analysis
Cards that join together sooner are more
similar to each other than those that join
together later
24. Cluster Analysis
Cards that join together sooner are more
similar to each other than those that join
together later
Join sooner = more similar
