Exemplar theory assumes that categorization is a process of learning about the exemplars that belong to the category . When an unfamiliar stimulus is encountered, its similarity is computed to the memory representation of every previously seen exemplar from each potentially relevant category.

In exemplar-based learning, such as the k-NN rule, objects are categorized by their similarity to one or more sets of stored examples, which can be represented as weighted feature vectors.
What are basic level categories?
Basic level categories, or generic level categories, are those categories in a folk taxonomy which are most culturally salient , and meet our basic cognitive needs the best.
