Re: Bar Chart Display
Good to know, thank you! I'll probably be posting here a bit more soon-ish, seems GeNie doesn't much care for working through a ~32k node network... but that is mostly my own fault for wanting to see lots of intermediate steps, and some overly large auto-generated node names. Hopefully i can compres...

Re: Bar Chart Display
Hello, Is the above still accurate? I'm planning to generate quite a big network using code, and would like to be able to view at a glance what the state/probability of quite a few nodes is, withouth having to set all of them to bar chart view manually. In the alternative, is it possible to set node...

Bug(?): DBN ignoring virtual evidence
Hello. It's not so much a problem for me, as i don't need the functionality (right now) but it appears GeNIe currently ignores virtual evidence when provided to a DBN. See the attached screenshots. If evidence of True is provided, inference works as expected. If evidence of 0.9999 True, 0.0001 False...

Re: Continuous value evidence discretisation for DBNs
Thanks for the reply.
Given my deadlines, i will go with the "pre-discretize data" workaround then.

Continuous value evidence discretisation for DBNs
Hello. First of all, happy new year. Second, the following: I'm aware that DBNs don't support continuous/equation nodes, and as far as i know this is not planned for the near future. I was wondering if it is possible to use the same discretization functionality that equation nodes have to translate ...

Re: SMILE 1.5 Released (includes rSMILE for use with R)
Cheers!
Is there a change log available?
From an earlier topic i assume data set matching for DBNs is included in this version, and i wanted to verify/check other changes/additions

Re: Parameter learner not optimising a DBN's temporal CPT's in PySMILE
I've manually set the ds.set_variable_names to ["working", "failed"] for all the nodes in ds, and the above issue still persists. In the origional data set, it looks as if the self t-1 CPT's for node 3 are indeed flipped, which would suggest that the behavior you mentioned (aplha...

Re: Parameter learner not optimising a DBN's temporal CPT's in PySMILE
I've created a manual matching by taking the regular matching and adding more DataMatch objects with modified slice and column values. For example, where normaly i would have: DataMatch.node = 1, DataMatch.column = 100, DataMatch.slice = 0 For a 100 time slice DBN, I added more DataMatch objects wit...

Re: Parameter learner not optimising a DBN's temporal CPT's in PySMILE
Thank you for the reply.
I have a intermediate deadline before that, so I'll create a manual matching in the mean time for that.
It is still good news i won't have to do that in future.

Parameter learner not optimising a DBN's temporal CPT's in PySMILE
I'm running into some trouble optimizing the parameters of a DBN with the PySMILE. In GENIE, the process is painless. Open the data file open the DBN, click learn parameters, confirm the time series, confirm the node matching and start the EM algorithm. However, when working with the wrapper, it see...

Re: Reading temporal arcs and small bug in SMILE wrapper documentation
After digging a bit though the available methods, for future reference, for the PySMILE wrapper there is a function net.get_max_temporal_order() which returns the maximum temporal order of arcs that exists in the network, and a function net.get_max_node_temporal_order(node) (i believe node can be ei...

Re: Reading temporal arcs and small bug in SMILE wrapper documentation
This has indeed been very helpful, thank you very much. One last question, is there a way to get all temporal arcs instantly, without iterating over every temporal order value, or a method that tells me which temporal order values contain arcs? It's not a huge issue if there isn't, but mainly from a...

Reading temporal arcs and small bug in SMILE wrapper documentation
Hello. I'm trying to read, from an existing model, which arcs exist. Reading normal arcs is no problem, indeed the tutorial has included hot to access that, but I'm having some trouble figuring out how to determine which temporal arcs exist. However, I'm running into some trouble when trying to dete...
