CPC is a recently proposed representation\nlearning framework based on predictive coding and noise contrastive estimation.\nWe focus on incorporating CPC features into the standard automatic speaker\nverification systems, and we present our methods, experiments, and analysis.\nThis thesis also details necessary background knowledge in past and recent work\non automatic speaker verification systems, conventional speech features, and\nthe motivation and techniques behind CPC.","url_abs":"http://arxiv.org/abs/1904.01575v1","url_pdf":"http://arxiv.org/pdf/1904.01575v1.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":"contrastive-predictive-coding-based-feature","repo_url":"https://github.com/jefflai108/Contrastive-Predictive-Coding-PyTorch","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":1,"framework":"pytorch","reach":null}],"tasks":[{"task_slug":"representation-learning","task_name":"Representation Learning"},{"task_slug":"speaker-verification","task_name":"Speaker Verification"}],"methods":[{"method_slug":"contrastive-predictive-coding","method_name":"Contrastive Predictive Coding"},{"method_slug":"infonce","method_name":"InfoNCE"}],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":"https://app.syntology.ai/?focus=1904.01575","mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
