Outline of Final Research Achievements

In this study, novel artificial glial neural networks that include features of glial cell are developed. The glial cell had been considered to support cell of neuron. Recently, researchers discovered that the glial cell transmits signal by using various important ions. Based on these researches, the artificial glial neural network includes these new features of glial cell such as a calcium wave by glial cell and glial cell working to a synapse plasticity. In one of proposed model based on glial cell working to synaptic plasticity, the glial cell makes neuron clusters and decides a dropout ratio in each neuron cluster. By this work, the influence of proposed glial dropout is better than the influence of original dropout for training of the neural network. The proposed deep glial neural networks compared with existing deep neural network, and this study confirmed that the proposed model has a high ability of the training and generalization capability.
