Concept acquisition normally proceeds from a set of positive and negative instances of some concept (or group of segregated concepts). With the presentation of the instances, the underlying algorithm makes correlations between the feature of the instances and their classification. The problem with this technique as it is described here is that it requires the specification of both relevant features and the possible concepts.
In general, as an inductive technique, concept acquisition should be able to generate new concepts spontaneously and to recognize the relevant features over the entire input domain.
