Re: Can the parameters of a DBN be learnt from "regular" time series data sets?

1. Can DBNs in GeNIe properly model cyber-physical systems, like building automation control? Of course, given that the structure is already defined by the user. Yes, the cyber-physical systems can and are actually modelled. One of our examples is based on the network used by one of our customers. ...

Re: Is it possible to specify equation bounds when learning using PC?

The default [-1, +1] bounds should be modified by the PC algorithm. It should be either an open interval (-inf,+inf), or values from the learning data, rounded or not.

I've added an item to our feature tracker, and we will make this modification before the next release.

Re: Is it possible to specify equation bounds when learning using PC?

The bounds can be edited after learning - simply enter -20 and 40 as lower and upper bound.

Re: missing value

GeNIe 4.1.4109 fixes this issue - the numeric replacement for missing values is converted to a valid SMILE id, and is visible as one of the node outcomes.

Re: clearEvidence without removing other nodes probabilities

Can you post your model here? Alternatively, send me a private forum message with a network attached or a download link.

Re: Genie 2 vs 4 - discretization triggered

Send me a private message on the forum, or an email to BayesFusion’s support account, Just to clarify the conditions which trigger discretization: an evidence set on any node with parents requires the discretization of the entire network. the evidence is set on a parent node only, not on any child n...

Re: Genie 2 vs 4 - discretization triggered

In the continuous or hybrid model, the discretization should be triggered when there's evidence in the nodes with parents. Can you share your network and the evidence which does not cause discretization in GeNIe 2.4? Without this information we cannot determine if this is a bug in old GeNIe 2.4, or ...

Re: Multiple genie versions on my PC

You can have multiple GeNIe versions installed on the same computer.

The SMILE (and its wrappers, including rSMILE) do not depend on GeNIe, and their multiple versions can be installed on the same machine.

Re: Calculating values in Python and returning them to pySMILE

Unfortunately, currently we don't have an option to defined an 'external function' in SMILE. By external function I mean SMILE calling into user-specified code, which processes inputs (in practice, a current sample value from parent node(s)), and returns a value which is treated by SMILE in the same...

Re: Calculating values in Python and returning them to pySMILE

Just to make sure we're on the same wavelength - what of the two options below describes your goal: a) you want to use stress_list in the same 'system.xdsl' model loaded into your Python program running PySMILE or b) you want to derive some SMILE-compatible expression to use in an equation node in o...

Re: Calculating values in Python and returning them to pySMILE

What values are is your stress_list? Depending on its structure, the form of the SMILE equation would be different. For example, if the list can be approximated as histogram, you could use the Steps function. Can you post actual values from stress_list? If it's a very long list, please limit it to f...

Is stress_list conditional on any of the nodes in your SMILE model?

Re: is there a function for calculating the log likelihood?

Sorry for the late reply. The most recent GeNIe build, version 4.1.3724, has a command which calculates the log likelihood for the network/dataset combination. This is implemented by calculating the sum of log(P(E)) values for each record in the dataset. SMILE will support this functionality in its ...

Re: Genie shuts down when I attempt to run a sensitivity analysis

We have just released GeNIe 4.1.3724, which fixes the crash.

Please note that influence diagrams without a single terminal node have their utilities and sensitivity calculated as if there was a single child ALU node connected to all terminal utilities.
