T. Nguyen","Ching-Hui Ooi","Andy W. H.

We propose an algorithm based on the directional sparse filtering (DSF) framework that utilizes the Lehmer mean with learnable weights to adaptively account for source imbalance. Performance evaluation in multiple real acoustic environments show improvements in source separation compared to the baseline methods.","url_abs":"https://arxiv.org/abs/2102.00196v3","url_pdf":"https://arxiv.org/pdf/2102.00196v3.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":"directional-sparse-filtering-using-weighted","repo_url":"https://github.com/karnwatcharasupat/directional-sparse-filtering-tf","is_official":1,"mentioned_in_paper":0,"mentioned_in_github":0,"framework":"tf","reach":null},{"paper_slug":"directional-sparse-filtering-using-weighted","repo_url":"https://github.com/e13000/directional_sparse_filtering","is_official":0,"mentioned_in_paper":1,"mentioned_in_github":0,"framework":"tf","reach":null}],"tasks":[{"task_slug":"audio-source-separation","task_name":"Audio Source Separation"},{"task_slug":"multi-speaker-source-separation","task_name":"Multi-Speaker Source Separation"},{"task_slug":"speech-separation","task_name":"Speech Separation"},{"task_slug":"blind-source-separation","task_name":"blind source separation"}],"methods":[{"method_slug":"directional-sparse-filtering","method_name":"Directional Sparse Filtering"}],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
