Abstract(in Japanese) (See Japanese page)
Abstract(in English) In this study, we propose a sequential learning method that improves recognition accuracy by alternately utilizing the knowledge obtained by semi-supervised and unsupervised learning, respectively. We investigate the relationship between recognition performance and learning time by varying the order and number of times each learning step and by applied sequentially. Numerical experiments will be conducted to confirm the effectiveness of the proposed method.
