| Description | Pattern recognition approaches fall into two main categories: supervised and unsupervised. Supervised systems require knowledge or data in which the outcome or classification is known ahead of time, so that the system can be trained to recognize and distinguish outcomes. Unsupervised systems cluster or group records without previous knowledge of outcome
or classification. The most frequently used unsupervised pattern recognition approach is principal component analysis (PCA). Other unsupervised methods include hierarchical clustering, k-means, and self organizing maps (SOM).
