--- abstract: |- Genetic Programming is extended so that the solutions being evolved do so in the context of local domains within the total problem domain. This produces a situation where different “species” of solution develop to exploit different “niches” of the problem – indicating exploitable solutions. It is argued that for context to be fully learnable a further step of abstraction is necessary. Such contexts abstracted from clusters of solution/model domains make sense of the problem of how to identify when it is the content of a model is wrong and when it is the context. Some principles of learning to identify useful contexts are proposed. altloc: - http://www.cpm.mmu.ac.uk/cpmrep78.html chapter: ~ commentary: ~ commref: ~ confdates: July 2001 conference: 'Third International and Interdisciplinary Conference on Modelling and Using Context, CONTEXT 2001' confloc: 'Dundee, UK.' contact_email: ~ creators_id: [] creators_name: - family: Edmonds given: Bruce honourific: '' lineage: '' date: 2001 date_type: published datestamp: 2001-08-30 department: ~ dir: disk0/00/00/17/72 edit_lock_since: ~ edit_lock_until: ~ edit_lock_user: ~ editors_id: [] editors_name: - family: Akman given: Varol honourific: '' lineage: '' - family: Bouquet given: Paolo honourific: '' lineage: '' - family: Thomason given: Richmond honourific: '' lineage: '' - family: Young given: Roger honourific: '' lineage: '' eprint_status: archive eprintid: 1772 fileinfo: /style/images/fileicons/application_pdf.png;/1772/1/lac.pdf|/style/images/fileicons/text_html.png;/1772/5/index.html 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: 'learning, conditions of application, context, evolutionary computing, error' lastmod: 2011-03-11 08:54:46 latitude: ~ longitude: ~ metadata_visibility: show note: ~ number: ~ pagerange: 143-155 pubdom: FALSE publication: ~ publisher: Springer-verlag refereed: TRUE referencetext: |- Aha, D.
