Unsupervised learning example.
Unsupervised learning is a branch of machine learning that is used to find underlying patterns in data and is often used in exploratory data analysis. Unsupervised learning does not use labeled data like supervised learning, but instead focuses on the data’s features. Labeled training data has a corresponding output for each input.
