Hello,
I've started using GeNIe to create Dynamic Networks but a don't understand how it's possible to insert a value in the conditional probability table of a node as a function of time. For example, if I have a temporal plate of 150 steps, I want to insert in a cell of the conditional probability table a value that changes with time : value = exp(-constant * dt), where dt is the time time step (for example equal to 1 minute). The result should be that at time=0 the value is 1 (exp(0) = 1), but with time passing this cell gains lower value.
Is it possible to do?
Thank you very much,
A.Ferrara

Re: Insert a data in the conditional periodic table as a function of time
What you want to do is to create a model of a non-stationary process, i.e., a process in which the underlying transition probabilities change over time. DBNs that we have in GeNIe are stationary and they do not allow for what you want to do. Of course, SMILE will allow you for anything, for example entering the CPTs into state nodes of an unrolled network. But this you will have to do in your program linked with SMILE.
I hope this helps.
