Assignment problems - Assignment problems allocate items from one set to items in another while optimizing an objective and satisfying matching constraints.
Associative classifier - An associative classifier is a supervised learning model that predicts a class using association rules.
Associative memory - Associative memory retrieves stored information from a cue related to its content, rather than requiring an exact storage address.
