In this paper, we propose the formation method of the expression feature map with a combination of supervised and unsupervised learning. First, hierarchical SOM having a small mapping space learns topological changes of complex face patterns and generates a reference vector of face patterns to characterize each expression. Next, CPN learns reference vectors of each expression and forms a category map based on topological changes of face patterns. Finally, the category map is created emotional meaning based on neutral and six basic facial expressions. We defined this category map as the expression feature map. The experimental results for six subjects indicated that the expression feature map defined individual expression features. |
