Unfortunately, it is challenging to approximate the WD of\nhigh-dimensional distributions. In contrast, the sliced Wasserstein distance\n(SWD) factorizes high-dimensional distributions into their multiple\none-dimensional marginal distributions and is thus easier to approximate. In\nthis paper, we introduce novel approximations of the primal and dual SWD.\nInstead of using a large number of random projections, as it is done by\nconventional SWD approximation methods, we propose to approximate SWDs with a\nsmall number of parameterized orthogonal projections in an end-to-end deep\nlearning fashion. As concrete applications of our SWD approximations, we design\ntwo types of differentiable SWD blocks to equip modern generative\nframeworks---Auto-Encoders (AE) and Generative Adversarial Networks (GAN). In\nthe experiments, we not only show the superiority of the proposed generative\nmodels on standard image synthesis benchmarks, but also demonstrate the\nstate-of-the-art performance on challenging high resolution image and video\ngeneration in an unsupervised manner.","url_abs":"http://arxiv.org/abs/1904.05408v2","url_pdf":"http://arxiv.org/pdf/1904.05408v2.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"sliced-wasserstein-generative-models-1","repo_url":"https://github.com/musikisomorphie/swd","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":1,"framework":"tf","reach":{"status":"ok"}}],"tasks":[{"task_slug":"image-generation","task_name":"Image Generation"},{"task_slug":"video-generation","task_name":"Video Generation"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[{"leaderboard":"/sota/image-generation-on-celeba-hq-1024x1024","task":"Image Generation","dataset":"CelebA-HQ 1024x1024","model":"PG-SWGAN","rank_in_archive_order":3,"of":10,"metrics":{"FID":"5.5"},"uses_additional_data":false},{"leaderboard":"/sota/image-generation-on-lsun-bedroom-256-x-256","task":"Image Generation","dataset":"LSUN Bedroom 256 x 256","model":"PG-SWGAN","rank_in_archive_order":15,"of":32,"metrics":{"FID":"8.0"},"uses_additional_data":false},{"leaderboard":"/sota/video-generation-on-trailerfaces","task":"Video Generation","dataset":"TrailerFaces","model":"PG-SWGAN-3D","rank_in_archive_order":1,"of":1,"metrics":{"FID":"404.1"},"uses_additional_data":false}],"syntology":{"atlas_url":"https://app.syntology.ai/?focus=1904.05408","mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
