Abstract

At present, nearly all neural networks are formulated bylearning only from examples or patterns. For a real-word problem,some forms of prior knowledge in a non-example form always exist.Incorporation of prior knowledge will benefit the formulation ofneural networks. Prior knowledge could be in several forms.Production rule is one form in which the prior knowledge isfrequently represented. This paper proposes an approach toincorporate production rules into neural networks. A newly definedneuron architecture, Boolean-like neuron, is proposed. With thisBoolean-like neuron, production rules can be encoded into the neuralnetwork during the network initialization period. Experiments aredescribed in this paper. The results show that the incorporation ofthis prior knowledge can not only increase the training speed, butalso the explainability of the neural networks.
