--- abstract: 'Real-world agents must react to changing conditions as they execute planned tasks. Conditions are typically monitored through time series representing state variables. While some predicates on these times series only consider one measure at a time, other predicates, sometimes called episodic predicates, consider sets of measures. We consider a special class of episodic predicates based on segmentation of the the measures into quasi-monotonic intervals where each interval is either quasi-increasing, quasi-decreasing, or quasi-flat. While being scale-based, this approach is also computational efficient and results can be computed exactly without need for approximation algorithms. Our approach is compared to linear spline and regression analysis.' altloc: [] chapter: ~ commentary: ~ commref: ~ confdates: 2005 conference: 'AAAI-05: Twentieth National Conference on Artificial Intelligence' confloc: Pittsburg USA contact_email: ~ creators_id: [] creators_name: - family: Fitzgerald given: Will honourific: '' lineage: '' - family: Lemire given: Daniel honourific: '' lineage: '' - family: Brooks given: Martin honourific: '' lineage: '' date: 2005 date_type: published datestamp: 2005-08-06 department: ~ dir: disk0/00/00/44/96 edit_lock_since: ~ edit_lock_until: ~ edit_lock_user: ~ editors_id: [] editors_name: [] eprint_status: archive eprintid: 4496 fileinfo: /style/images/fileicons/application_pdf.png;/4496/1/episode_web.pdf full_text_status: public importid: ~ institution: ~ isbn: ~ ispublished: pub 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: ~ lastmod: 2011-03-11 08:56:09 latitude: ~ longitude: ~ metadata_visibility: show note: ~ number: ~ pagerange: ~ pubdom: FALSE publication: ~ publisher: ~ refereed: TRUE referencetext: ~ relation_type: [] relation_uri: [] reportno: ~ rev_number: 12 series: ~ source: ~ status_changed: 2007-09-12 17:00:20 subjects: - comp-sci-art-intel succeeds: ~ suggestions: ~ sword_depositor: ~ sword_slug: ~ thesistype: ~ title: Quasi-monotonic segmentation of state variable behavior for reactive control type: confpaper userid: 4175 volume: ~
