Abstract:
Based on biological prototype of human brain and
improved understanding of the functionality of the
neurons and the pattern of their interconnections in the
brain, a theoretical model used to explain the
information-processing characteristics of the cerebellum
was developed independently by Marr (1969) and Albus
(1971). Cerebellar model articulation controller (CMAC)
was first proposed by Albus in 1974. CMAC is a learning
structure that imitates the organization and
functionality of the cerebellum of the human brain. That
model revealed the structure and functionality of the
various cells and fibers in the cerebellum. The core of
CMAC is an associative memory which has the ability to
approach complex nonlinear functions. CMAC takes
advantage of the input-redundancy by using distributed
storage and can learn nonlinear functions extremely
quickly due to the on-line adjustment of its system
parameters. CMAC is classified as a non-fully connected
perceptron-like associative memory network with
overlapping receptive-fields. It has good generalization
capability and fast learning property and is suitable
for a lot of applications. This speech introduces
several CMAC-based adaptive learning systems; these
systems combine the advantages of CMAC identification,
adaptive learning and control techniques. In these
systems, the on-line parameter training methodologies,
using the gradient descent method and the Lyapunov
stability theorem, are proposed to increase the learning
capability. Moreover, the applications of these systems
in servomotor control, biped robot and computer-aided
diagnostic of breast nodules are demonstrated.
