The patterns you uncover with unsupervised machine learning methods may also come in handy when implementing supervised machine learning methods later on. For example, you might use an unsupervised technique to perform cluster analysis on the data, then use the cluster to which each row belongs as an extra feature in the supervised learning model…

8 Hierarchical clustering uses Euclidean distance automagically, but it may also use other similarity metrics such as for example correlation-based distance, which we shall explore in more detail later in the book. Unlike k-means, we need not prespecify the amount of clusters. DBSCAN is a lot less prone to the distortion typically due to outliers…
