Naredni sastanak Seminara za primenjenu matematiku održaće se u utorak, 28. juna 2011. u 14:15 h na Matematičkom institutu SANU, sala 301f, 3. sprat.

Predavači: Zoran Obradović, Director, Center for Data Analytics and Biomedical Informatics, Temple University, Philadelphia, USA

Naslov predavanja: SPATIO-TEMPORAL ANALYSIS OF MULTI-SOURCE DATA IN REMOTE SENSING

ABSTRACT: In this talk we will first present an overview of the results obtained over the last five years on our data mining based study aimed at understanding spatio-temporal distribution of aerosol by taking advantage of collected measurements from multiple ground and satellite-based sensors. In more details we will describe our recent method for information fusion and learning from data of varying quality based on Continuous Conditional Random Fields. Finally, we will discuss our effective method for learning from spatio-temporal data with a large fraction of missing values. This method that will be published at IJCAI 2011 outperformed alternatives when imputing 80% of nonrandom missing values in aerosol observations. Using such enlarged data we have developed a predictor of aerosol optical depth that was much more accurate than predictors based on alternative imputation methods when tested rigorously over entire continental US in year 2005.
