Smoothing CPTs after incorporating a case file

Here's a big quandary many of us are facing: when you use a case file to induce probability values in a Bayes net (esp. in Netica), such as with the expectation maximization (EM) algorithm or a similar approach, often the resulting conditional probability table (CPT) contains a lot of "holes&qu...

Integrating BN models with GIS

Is anyone using GeoNetica, or an API connection to GIS, or some other means? In past projects, colleagues and I have linked Bayesian network models to ArcMap, ArcGIS maps by using polygon conditions as input files to the BN models as case files, then generating and saving the BN model output which i...

Modeling Climate Change Impacts

Who is using Bayesian networks for modeling dynamics and impacts of climate change? So far, I've collaborated with biologists and climate modelers on evaluating future conditions for polar bears, Pacific walrus, and wildlife habitats in northern and northwest Alaska, using BN models. I've also seen ...
