Probabilistic Embeddings Revisited

In recent years, deep metric learning and its probabilistic extensions achieved state-of-the-art results in a face verification task. However, despite improvements in face verification, probabilistic methods received little attention in the community. It is still unclear whether they can improve image retrieval quality. In this paper, we present an extensive comparison of probabilistic methods in verification and retrieval tasks. Following the suggested methodology, we outperform metric learning baselines using probabilistic methods and propose several directions for future work and improvements.
