DISCUSS UNOBSERVABLES IN THE INTRO? % In this paper, we develop a Bayesian approach towards this end. % We use a detailed causal model of the decision making process, taking into account also unobserved features. Based on this model, we evaluate counterfactual outcomes to correct any aforementioned biases. % to infer unobserved outcomes. % Compared to previous methods for this setting, the approach estimates the quality of decisions more accurately and with lower variance. % The approach is also %demonstrated to be robust to different variations in the decision mechanisms in the data. % \end{abstract} \begin{document} \fancyhead{} \maketitle \renewcommand{\shortauthors}{Authors} \input{introduction} \input{setting} \input{imputation} \input{experiments} \input{related} \input{conclusions} % \textbf{Acknowledgments.} %The computational resources must be mentioned. %\clearpage % \balance \bibliographystyle{ACM-Reference-Format} \bibliography{biblio} %\balancecolumns % GM June 2007 %\clearpage \input{appendix} \end{document}
