Given a workload of counting queries, the mechanism automatically selects a different set of \"strategy\" queries to answer privately, using those answers to derive answers to the workload. The main algorithm proposed in this paper approximates the optimal strategy for any workload of linear counting queries. With no cost to the privacy guarantee, the mechanism improves significantly on prior approaches and achieves near-optimal error for many workloads, when applied under (\u03b5, \u03b4)-differential privacy. The result is an adaptive mechanism which can help users achieve good utility without requiring that they reason carefully about the best formulation of their task.<\/jats:p>","DOI":"10.14778\/2168651.2168653","type":"journal-article","created":{"date-parts":[[2014,6,24]],"date-time":"2014-06-24T12:17:57Z","timestamp":1403612277000},"page":"514-525","source":"Crossref","is-referenced-by-count":62,"title":["An adaptive mechanism for accurate query answering under differential privacy"],"prefix":"10.14778","volume":"5","author":[{"given":"Chao","family":"Li","sequence":"first","affiliation":[{"name":"University of Massachusetts, Amherst, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gerome","family":"Miklau","sequence":"additional","affiliation":[{"name":"University of Massachusetts, Amherst, Massachusetts"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"320","published-online":{"date-parts":[[2012,2]]},"reference":[{"key":"e_1_2_1_1_1","unstructured":"http:\/\/abel.ee.ucla.edu\/cvxopt\/.  http:\/\/abel.ee.ucla.edu\/cvxopt\/."},{"key":"e_1_2_1_2_1","unstructured":"http:\/\/dbgroup.cs.umass.edu\/code\/.  http:\/\/dbgroup.cs.umass.edu\/code\/."},{"key":"e_1_2_1_3_1","unstructured":"http:\/\/www.mcs.anl.gov\/hs\/software\/dsdp\/.  http:\/\/www.mcs.anl.gov\/hs\/software\/dsdp\/."},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1145\/1265530.1265569"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.5555\/993483"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.1109\/ICDE.2012.16"},{"key":"e_1_2_1_7_1","doi-asserted-by":"publisher","DOI":"10.1145\/1989323.1989347"},{"key":"e_1_2_1_8_1","doi-asserted-by":"publisher","DOI":"10.1145\/1866739.1866758"},{"key":"e_1_2_1_9_1","doi-asserted-by":"publisher","DOI":"10.1007\/11761679_29"},{"key":"e_1_2_1_10_1","doi-asserted-by":"publisher","DOI":"10.1007\/11681878_14"},{"key":"e_1_2_1_11_1","doi-asserted-by":"publisher","DOI":"10.1145\/1536414.1536464"},{"key":"e_1_2_1_12_1","doi-asserted-by":"publisher","DOI":"10.1109\/FOCS.2010.85"},{"key":"e_1_2_1_13_1","doi-asserted-by":"publisher","DOI":"10.14778\/1920841.1920970"},{"key":"e_1_2_1_14_1","doi-asserted-by":"publisher","DOI":"10.1145\/1807085.1807104"},{"key":"e_1_2_1_15_1","unstructured":"C.
