Deep Learning Generic Features for Cross-Media Retrieval.

Cross-media retrieval is an imperative approach to handle the explosive growth of multimodal data on the web. However, how to effectively uncover the correlations between multimodal data has been a barrier to successful retrieval of cross-media data. The traditional approaches learn the connection between multiple modalities by direct utilization of hand-crafted low-level heterogeneous features and the learned correlation are merely constructed in terms of high-level feature representation. To well exploit the intrinsic structures of multimodal data, it is essential to build up an interpretable correlation between multimodal data. In this paper, we propose a deep model to learn the high-level feature representation shared by multiple modalities for cross-media retrieval. We learn the discriminative high-level feature representation in a data-driven manner before faithfully encoding the multimodal correlations. We use the large-scale multimodal data crawled from Internet to train our deep model and evaluate its effectiveness on cross-media retrieval based on NUS-WIDE dataset. The experimental results show that the proposed model outperforms other state-of-the-arts approaches.
