Modality-Dependent Cross-Modal Retrieval Based on Graph Regularization

Algorithm 1

Modality-dependent cross-modal retrieval based on graph regularization in I2T.

	Input: training image datasets ;
	Training text datasets ;
	Semantic sets
	Balancing parameters λ, α, ,
	Output: projection matrices and .
	1: calculate the graph Laplacian matrix ;
	2: initialize and to be identity matrices;
	3: repeat
	4: fix and update according to (14);
	5: fix and update according to (15);
	6: until convergence
	7: end for
