In this paper, based on the deeper analysis of the features of fuzzy l
ogic and approximate reasoning, the concept of approximate case-based
reasoning (ACBR) is introduced. According to the inference mechanism o
f ACBR, an implementation on neural networks is proposed. Mapping the
implication relation between the premise(s) and the consequence of a f
uzzy rule to the weight of a corresponding neural network unit, an app
roximate case-based reasoning on neural networks can be realized. The
self-organizing and self-learning procedure can be executed by modifyi
ng the weight.
