One of my Cranfield colleagues said that to me the other day, and I'm fully aware I'm not camera shy, but if someone was using my face in some sort of modelling campaign then I wanted to know about it, so I could tell everyone! It was a few seconds into the conversation before I realised they were talking about my survey, modelling my data and Bayesian belief networks (BBN).
Now, I'm not an expert on BBN, as yet, so I have included a link to the wikipedia site which has some great links on it if you want to read a bit more into it.
What I know is that I can use BBN to model my data in a way that allows me to see the degree of belief that a child node will be in a particular state given the states of the parent nodes. This sentence took a while for me to understand, but if you see the picture below, you can see that the 'LocalIs' and 'TemporalScaleWork' boxes are the child nodes and the 'Policy' box is the parent node.
I really like using BBN and I use the Norsys Netica software to build my networks, it's very user friendly, and has a great 'help' mode.One of the best things that has come of this so far is that I have managed to start answering my own questions about BBN, so I really feel like I'm getting a grasp of how it all works.
