Effective multiple feature fusion using topic model for social image visualization

This paper presents a multiple feature fusion method using topic model for social image visualization. Images in social media are represented from several aspects such as their visual information and tags. The proposed method extracts low-level features from social images and their tags and calculates their integrated high-level features. Specifically, the proposed method applies multilayer multimodal probabilistic Latent Semantic Analysis (mm-pLSA) to the low-level visual and tag features to obtain the high-level features. Then, by applying dimensionality reduction techniques to the obtained features, successful visualization becomes feasible.
