Moreover, the policy embodied a discourse which portrayed teachers as empowered and, consequently, as the primary source of problems of its implementation.

    Evolutionary Discovery of Fuzzy Concepts in Data
    with Lewis L. H. Chung
    Brain and Mind 4 (2): 253-268. 2003.
    Given a set of objects characterized by a number of attributes, hidden patterns can be discovered in them for the grouping of similar objects into clusters. If each of these clusters can be considered as exemplifying a certain concept, then the problem concerned can be referred to as a concept discovery problem. This concept discovery problem can be solved to some extent by existing data clustering techniques. However, they may not be applicable when the concept involved is vague in nature or wh…Read more
