Appendix: A Differentiable Semantic Metric Approximation in Probabilistic Embedding for Cross-Modal Retrieval Hao Li

In this supplementary material, we discuss the following topics: Firstly, we discuss why we adopt Eq. 1 as the formulation of ASP in Appendix. A. Then, we analyze the differences between two Furthermore, the effect of different semantic metrics on DAA is explored in Appendix. A How ASP Formulation is Designed? The formulation of ASP in the paper is as Eq. 1. The vector above each image is the class label of the image.
