Spreadsheet Probabilistic Programming [article]

Mike Wu, Yura Perov, Frank Wood, Hongseok Yang
2016 arXiv   pre-print
For spreadsheet end-users this would mean having access to efficient and probabilistically coherent probabilistic modeling and inference for use in all kinds of decision making under uncertainty.  ...  Spreadsheet workbook contents are simple programs. Because of this, probabilistic programming techniques can be used to perform Bayesian inversion of spreadsheet computations.  ...  Additionally, knowing that the spreadsheet graphical model has a finite number of random variables allows us to implement black-box variational inference (BBVI).  ...

In this paper we present our work on extending a widely used spreadsheet system with such a model-driven spreadsheet engineering environment.  ...  End users can interact with both the model and the spreadsheet data in the same environment. Moreover, we use advanced techniques to evolve spreadsheets and models and to have them synchronized.  ...  Our approach closes the gap between creating and using a domain specific language for spreadsheet models and a totally different framework for actually editing spreadsheet data.  ...
