Glossary

Authentication Verifying the identity of a sample using a test of genuineness. It generally involves a one-to-one comparison with the genuine (authentic) sample. Categorisation Assigning a data sample to a class according to certain distinguishing properties (or characteristics) of that class, and it generally involves a one-to-many test in which one data sample is compared with the characteristics of several classes. Classification Assigning labels to patterns Clustering Grouping data samples in groups or classes based on their properties (or characteristics) and it generally involves a many-to-many (dis)similarity test. Grouping or separating patterns according to their closeness or dissimilarity. Feature extraction Deriving descriptive or quantitative measures from data. Identification In the context of collecting of data samples, identification means selecting a particular sample having a (predefined) characteristic which distinguishes it from the others. Several data samples are generally matched against the characteristic sample in a many-to-one process. Pattern patterns Data having characteristic regularity, or a representation derived from it, having some explanatory value or being able to provide an interpretation.
