Hi
I am working with chain graphs and have heard that there exists some implementation for handling these in Hugin. From your homepage I can see that it is shown as a feature (
http://www.hugin.com/productsservices/products/feature-list) and there are also references to it when the .net format is explained in for example the API manual (example 13.5 to 13.7). The manual does however not explain how to set the data table for the potentials and when I play around with it myself I can't get it right.
So my questions are:
1. What functionality of chain graphs are supported by the Hugin GUI and the Hugin API?
2. If the API does not support direct adding and removing undirected edges (and setting corresponding potentials), how would one do this directly by manipulating the .net file. I.e. what would you write instead of dots in
potential (C3 C4 | C1 C2)
{
data = ...
}
when handling a chain graph with the structure C1 -> C3 -- C4 <- C1 to get the right independence model and how can this model be used for inference using the Hugin inference engine?
3. Does it also exist support (in the inference engine etc.) for using continuous nodes when using chain graphs. I.e. for multivariate normal distributions over the nodes in the chain component?
Thanks beforehand for any answer! Great program!
