Abstract:

Modelling cause and effect relationships has been a major challenge for
statisticians in a wide range of application areas. Bayesian Networks (BN),
Context Statistical Process Control (CSPC),Variable Order Bayesian Networks
(VOBN) and Target-Based Bayesian Networks combine graphical analysis with
Bayesian analysis to represent causality maps linking measured and target
variables (Pearl, 2000, Ben Gal, 2003, 2004, 2007, Kenett, 2007, Cornalba et
al, 2007, Gruber and Ben-Gal 2011). Such mapping models can be used for
effective process monitoring. The talk will present an introduction to
Bayesian Networks and their applications in the context of the amount of
data available. We distinguish between small data sets, with multivariate
observations over 5-15 time instances, mid-range data sets with data
collected over 100-500 time stamps and massive data sets with thousand and
even millions data points. The examples we cover include the testing of web
services (Bai and Kenett, 2012), bioinformatics (Grau et al, 2008) and web
site usability analysis with massive data sets (Harel et al, Kenett et al,
2009), customer satisfaction surveys (Kenett and Salini, 2011) and
operational risks with midrange data sets (Kenett and Raanan, 2010),
healthcare systems (Kenett, 2012), and biotechnology with small data sets
(Peterson and Kenett, 2011). We will discuss various challenges in dealing
with complex data sets and provide an introduction to the European ambitious
FuturICT project (www.futurict.eu) that aims at handling planet level data
sets.
