In unsupervised learning, the machine is trained on a set of unlabeled data, which means that the input data is not paired with the desired output. The machine then learns to find patterns and relationships in the data. Unsupervised learning is often used for tasks such as clustering, dimensionality reduction, and anomaly detection.One of the most commonly used techniques of unsupervised learning is clustering. As the name suggests, clustering is the act of grouping data that shares similar characteristics. In machine learning, clustering is used when there are no pre-specified labels of data available, i.e. we don’t know what kind of groupings to create.Photo by Nathan Anderson @unsplash.com.
