In this paper, we propose a new information theoretic method called structural information to overcome fundamental problems inherent in conventional competitive learning such as dead neurons and deciding on the appropriate number of neurons in the competitive layer. Our method is based on defining and controlling several kinds of information, thus generating particular neuron firing patterns. For one firing pattern, some neurons are completely inactive, meaning that some dead neurons are generated. For another firing pattern, all neurons are active, that is, there are no dead neurons. This means that we can control the number of dead neurons and choose the appropriate number of neurons by controlling information content. We applied this method to simple pattern classification to show that information can be controlled, and that different neuron firing patterns can be generated.
