--- abstract: We present and test an extension of slow feature analysis as a novel approach to nonlinear blind source separation. The algorithm relies on temporal correlations and iteratively reconstructs a set of statistically independent sources from arbitrary nonlinear instantaneous mixtures. Simulations show that it is able to invert a complicated nonlinear mixture of two audio signals with a reliability of more than $90$\%. The algorithm is based on a mathematical analysis of slow feature analysis for the case of input data that are generated from statistically independent sources. altloc: [] chapter: ~ commentary: ~ commref: ~ confdates: ~ conference: ~ confloc: ~ contact_email: ~ creators_id: - henning.sprekeler@epfl.ch - tiziano.zito@bccn-berlin.de - l.wiskott@biologie.hu-berlin.de creators_name: - family: Sprekeler given: Henning honourific: Dr. lineage: '' - family: Zito given: Tiziano honourific: '' lineage: '' - family: Wiskott given: Laurenz honourific: Dr. lineage: '' date: 2010-10 date_type: submitted datestamp: 2010-10-18 11:03:37 department: ~ dir: disk0/00/00/70/56 edit_lock_since: ~ edit_lock_until: 0 edit_lock_user: ~ editors_id: [] editors_name: [] eprint_status: archive eprintid: 7056 fileinfo: /style/images/fileicons/application_pdf.png;/7056/1/SprekelerZitoWiskott%2DCogprints%2D2010.pdf full_text_status: public importid: ~ institution: ~ isbn: ~ ispublished: ~ issn: ~ item_issues_comment: [] item_issues_count: 0 item_issues_description: [] item_issues_id: [] item_issues_reported_by: [] item_issues_resolved_by: [] item_issues_status: [] item_issues_timestamp: [] item_issues_type: [] keywords: 'slow feature analysis, nonlinear blind source separation, independent component analysis' lastmod: 2011-03-11 08:57:45 latitude: ~ longitude: ~ metadata_visibility: show note: ~ number: ~ pagerange: ~ pubdom: TRUE publication: ~ publisher: ~ refereed: FALSE referencetext: ~ relation_type: [] relation_uri: [] reportno: ~ rev_number: 40 series: ~ source: ~ status_changed: 2010-10-18 11:03:37 subjects: - comp-sci-mach-learn succeeds: 7055 suggestions: ~ sword_depositor: ~ sword_slug: ~ thesistype: ~ title: An Extension of Slow Feature Analysis for Nonlinear Blind Source Separation type: preprint userid: 6764 volume: ~
