Unsupervised Learning
Finding structure in data that has no labels attached.
Last updated
Unsupervised learning looks for patterns without a target answer. Clustering groups similar records, and dimensionality reduction compresses data while preserving relationships. It is useful for exploration, anomaly detection and building the embeddings that power search and recommendations. Because there is no label to check against, interpreting the results takes care.
