Summary Chapter 5
In Chapter 5, we explored the key unsupervised learning techniques that allow models to learn patterns and structures in data without the need for labeled examples. Unsupervised learning is widely used in tasks such as clustering, dimensionality reduction, and anomaly detection. This chapter delved into various methods that help uncover the hidden structures in datasets, particularly when working with high-dimensional data.
We began with clustering algorithms, which group data points based on similarity. The three primary clustering methods discussed were K-Means, Hierarchical Clustering, and DBSCAN. K-Means is a simple yet effective algorithm that partitions data into a specified number of clusters, making it ideal for well-separated ...
