Equation Model

Post by cpm827 »

Hello! I have an equation model which i will like to convert into a dynamic Bayesian network, is this possible in GeNIe ?

Re: Equation Model

Not quite yet but please stay tuned -- we should have it later this year. At the moment, what you can do is create a static hybrid model (i.e., with equation nodes) that has variables at time t and then t-1 (assuming links of the first order). Once you have that, you can use your static model for generation of CPTs for your DBN. Please find enclosed two models that I used to implement a discrete dynamic predator-prey model involving Lotka-Volterra equations. I generated the CPTs in the static model and just copied and pasted them into the DBN. I hope this helps. If you give us some months, we will have DBNs that have equation nodes within them.
Cheers,

Marek
