Jun 22, 2016 · We present a technique for incorporating data attributes that are supposed Missing Not at Random (MNAR) into Bayesian. Networks (BNs).
In this work we explore the Perturb and Combine idea, celebrated in supervised learning, in the context of probability density estimation in ...
Finally, we propose two methods that can be used to inform a decision maker of the possible effects of presumed MNAR data into the EVPI calculation. Future ...
