Seminar on Computer Science and Applied Mathematics
Upravni odbor Matematickog instituta SANU je na nedavnoj sednici doneo odluku da se dosadasnji Seminar za primenjenu matematiku, sada nazove Seminar za racunarstvo i primenjenu matematiku, a u cilju potenciranja znacaja racunarstva kao jedne od oblasti delatnosti Instituta. Istovremeno, Upravni odbor doneo je odluku o osnivanju Odeljenja za racunarstvo i primenjenu matematiku i vezao rad novog odeljenja za rad Seminara za racunarstvo i primenjenu matematiku.

UTILIZING TEMPORAL PATTERNS FOR ESTIMATING UNCERTAINTY IN INTERPRETABLE EARLY DECISION MAKING
Abstract: Providing classification of time series as early as possible is vital in many domains including the medical, where early diagnosis can save patients. lives by providing early treatment. However, applications often require the method to be interpretable and have uncertainty estimates. These two aspects were not jointly addressed in previous studies, such that a difficult choice of selecting one of these aspects is required. To address this problem, in this study we propose a simple and yet effective method to provide uncertainty estimates for an interpretable early classification algorithm recently developed in our laboratory. The question we address here is "how to provide estimates of uncertainty in regard to interpretable early prediction." We showed that the proposed method is more effective than the state-of-the-art alternatives in providing reliability estimates in early classification, is simple to implement, and provides interpretable results.
This is joint research with M. Ghalwash and V. Radosavljevic and the results will be published at the Proc. 20th ACM SIGKDD Conf. on Knowledge Discovery and Data Mining, New York, NY, Aug. 2014.
