Semi-Supervised Cross-Modal Retrieval Based on Discriminative Comapping

Figure 7

Convergence curves of the objective function value using Algorithm 1 on Wikipedia and Pascal datasets. The figure shows that the objective function value monotonically decreases until convergence by applying the iterative algorithm. (a) Image query on wiki-W. (b) Text query on wiki-W. (c) Image query on Pascal. (d) Text query on Pascal.
