Conventional\u00a0nonparametric<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">regression methods, however, are only appropriate for\u00a0estimating continuous<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">regression functions. When a underlying\u00a0regression function has jumps,<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">functions estimated by the conventional\u00a0methods are not statistically consistent<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">at the jump positions. Recently,\u00a0jump regression analysis (JRA) for estimating<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">jump regression functions\u00a0is under rapid development, because JRA has broad<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">applications. One\u00a0important application is image processing where a<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">monochrome image\u00a0can\u00a0be regarded as a surface of the image intensity<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">function which has jumps\u00a0at the outlines of image objects. In this talk, I will<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">make a general introduction\u00a0to the research area of JRA and some of its<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">applications in image processing.\u00a0At the beginning of the talk, I will spend<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">several minutes to briefly describe\u00a0some of my other research topics.<\/p>\n\n\n\r\n\t\t\t<\/div>\r\n\t\t<\/div>\r\n\t<\/div>\r\n<\/section>\r\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":146,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":false,"featured_post":"","footnotes":"","_links_to":"","_links_to_target":""},"class_list":["post-453","page","type-page","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/people.clas.ufl.edu\/boyland\/wp-json\/wp\/v2\/pages\/453","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/people.clas.ufl.edu\/boyland\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/people.clas.ufl.edu\/boyland\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/people.clas.ufl.edu\/boyland\/wp-json\/wp\/v2\/users\/146"}],"replies":[{"embeddable":true,"href":"https:\/\/people.clas.ufl.edu\/boyland\/wp-json\/wp\/v2\/comments?post=453"}],"version-history":[{"count":3,"href":"https:\/\/people.clas.ufl.edu\/boyland\/wp-json\/wp\/v2\/pages\/453\/revisions"}],"predecessor-version":[{"id":4062,"href":"https:\/\/people.clas.ufl.edu\/boyland\/wp-json\/wp\/v2\/pages\/453\/revisions\/4062"}],"wp:attachment":[{"href":"https:\/\/people.clas.ufl.edu\/boyland\/wp-json\/wp\/v2\/media?parent=453"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
