Cluster-based Joint Matrix Factorization Hashing for Cross-Modal Retrieval

  title={Cluster-based Joint Matrix Factorization Hashing for Cross-Modal Retrieval},
  author={Dimitrios Rafailidis and Fabio Crestani},
Cross-modal retrieval has been an emerging topic over the last years, as modern applications have to efficiently search for multimedia documents with different modalities. In this study, we propose a cross-modal hashing method by following a cluster-based joint matrix factorization strategy. Our method first builds clusters for each modality separately and then generates a cross-modal cluster representation for each document. We formulate a joint matrix factorization process with the constraint… CONTINUE READING
