I have search and saw some questions on the matter but without answer (due to the fact that the questions were asked more than 1 year ago, I. hoped something has changed)

I am looking for a library to infer bayesian network from a file of continious variables is there anything simple\out of the box that any one has encountered? I have tried pyAgrum for example but when i run

pyAgrum.BNLearner(numdata).learnDAG()

I get

Exception: [pyAgrum] Wrong type: Counts cannot be performed on continuous variables. Unfortunately the following variable is continuous: V0

Have tried serval libraries but they all seem to work only on discrete variables would love some help in advance.

The main question is what kind of model do you want for your continuous variables.

1- Do you want them to be discretized : you can have a look for instance at http://webia.lip6.fr/~phw/aGrUM/docs/last/notebooks/Discretizer.ipynb.html.

2- Do you want to assume a linear gaussian model : you can have a look for instance at bnlearn (https://haipengu.github.io/Rmd/GBN.html)

3- Do you want to learn more general continuous model : You can have a look at for instance otagrum (http://openturns.github.io/otagrum/master/) which learns copula bayesian network.

4- etc.

  • This should be a comment. Answers must answer the question. A link to a resource is not an answer. – Pranav Hosangadi Sep 28 '21 at 21:31
  • The question is to find a library to infer Bayesian network from a file of continuous variables. The answer proposes links to 3 different libraries to infer Bayesian network from continuous data. – Pierre-Henri Wuillemin Sep 28 '21 at 21:42
  • Questions asking for library recommendations are specifically mentioned as [off-topic](/help/on-topic). You could demonstrate how to do what OP wants with one of your suggested libraries and that would be a great answer, but "check this library out" is not an answer. – Pranav Hosangadi Sep 28 '21 at 21:59
  • I agree that the question is off-topic but the answer does answer the question "*I am looking for a library ...*". I don't agree that an example creating data and illustrating a package should be added to the answer as this would also be off-topic as SO is not about providing tutorials but answering specific programming questions. ps I hadn't heard of otaGrum so thanks for the heads up. – user20650 Sep 29 '21 at 11:08
