Unsupervised machine learning is a category of artificial intelligence where algorithms learn from unlabeled data. Unlike supervised learning, there are no predefined outputs or training labels provided to guide the model.

These algorithms uncover hidden patterns, intrinsic structures, and relationships within data. This makes them highly valuable in exploratory data analysis and tasks involving high-dimensional or unstructured datasets.

Common techniques include clustering methods like k-means and DBSCAN, dimensionality reduction using PCA or t-SNE, and anomaly detection in cybersecurity and finance.
