I'm no expert, but I had the same problem today and it seemed like the solution was to set {0.5,0.5,0,1,0.5,0.5,0,1,0,1} i.e. include the constrained columns.

Re: strengths field in noisyMax node

Thanks for your response :) Turns out I was getting confused by the way Genie files get imported into Samiam, which seems to combine chained noisy-or nodes together, thereby increasing the number of values in the strengths field of the child nodes. The upshot being that I was confused about how many ...

Accessing cluster joint probabilities after inference

I'm interested in running a modified version of EM to learn the parameters of a series of separate (different) bayesian networks with common parameters. It doesn't look like I can use the existing EM functions for this.

So in order to do this, I think I need to access the values of P(X,U|evidence ...

strengths field in noisyMax node

Hi,

I'm trying to build a network in .xdsl format that contains Noisy Or nodes. I'm confused by the strengths field in the NoisyMax node.

I've read the explanation in the reference manual (http://genie.sis.pitt.edu/wiki/Reference_Manual:_DSL_noisyMAX) and it doesn't make sense to me. Can someone ...
