Welcome to Unit 7Unsupervised Learning – Clustering
In this unit, we transition to unsupervised learning, where we work with unlabeled data to uncover hidden patterns and structures. Clustering is one of the most powerful techniques in unsupervised learning, and it is used to group similar data points together. We will also discuss K-means clustering, a widely used and intuitive method for partitioning data into distinct clusters. You will learn how to implement K-means clustering using Python to determine the optimal number of clusters for a given dataset. A key part of the clustering process is analyzing and interpreting the results. We will explore methods for evaluating the quality of clusters and visualizing cluster assignments, which will help you gain deeper insights into the underlying structure of your data. Clustering has many practical applications, such as customer segmentation, anomaly detection, and data exploration. By the end of this unit, you will be equipped to implement and interpret clustering models, uncover hidden patterns in your data, and make informed, data-driven decisions. You can start by reviewing the unit learning outcomes and then reviewing the unit resources.
