| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper proposes a new technique named Stacked Non-negative Matrix Factorization (sNMF), which factorizes multiple non-negative matrices that are mutually related. The model is formulated as a generalization of the standard NMF, and also can be seen as a special case of NMF with undefined sub matrices. In this paper, we apply sNMF to an emerging social media analysis. More specifically, we employ sNMF to detect topics and find credible user clusters behind social media dataset. Experimental results show that sNMF performs much better than the standard NMF quantitatively, and successfully reveal reasonable topics and user clusters from social media dataset. |
