{"pk":28064,"title":"Data Availability and Function Extrapolation","subtitle":null,"abstract":"In function learning experiments, where participants learnrelationships from sequentially-presented examples, peopleshow a strong tacit expectation that most relationships are lin-ear, and struggle to learn and extrapolate from non-linear rela-tionships. In contrast, experiments with similar tasks wheredata are presented simultaneously – typically using scatterplots – have shown that human learners can discover and ex-trapolate from complex non-linear trends. Do people have dif-ferent expectations in these task types, or can the results beattributed to effects of memory and data availability? In a di-rect comparison of both paradigms, we found that differencesbetween task types can be attributed to data availability. Weshow that a simple memory-limited Bayesian model is consis-tent with human extrapolations for linear data for both highand low data availability. However, our model underestimatesthe participants’ ability to infer non-monotonic functions, es-pecially when data is sparse. This suggest that people trackhigher-order properties of functions when learning and gen-eralizing.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Function learning"},{"word":"function estimation"},{"word":"resource rationality"}],"section":"Publication-based-Talks","is_remote":true,"remote_url":"https://escholarship.org/uc/item/36x9d07k","frozenauthors":[{"first_name":"Pablo","middle_name":"Leon","last_name":"Villagra","name_suffix":"","institution":"University of Edinburgh","department":""},{"first_name":"Irina","middle_name":"","last_name":"Preda","name_suffix":"","institution":"University of Edinburgh","department":""},{"first_name":"Christopher","middle_name":"G","last_name":"Lucas","name_suffix":"","institution":"University of Edinburgh","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2018-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/28064/galley/17703/download/"}]}
