bnlearn, hill-climbing algorithm: how can I get alternative structures in the order of score?

In the R package of "bnlearn", the function "hc" only derives the most plausible structure in a score (e.g., bic, aic). But, I want to know alternative structures in the order of plausibility (i.e., score). For example, when three nodes were given…

Causality map changing when order of the variables are changed

I am using bnlearn and pcalg R packages to obtain the causality map from the datasets. There is an order-independent algorithm which claims to be independent of variables are given as input. When I change the order the variables, directions of…

R package bnlearn: cpquery vs predict - different results?

I want to use my bayesian network as a classifier, first on complete evidence data (predict), but also on incomplete data (bnlearn::cpquery). But it seems that, even working with the same evidence, the functions give different results (not only…

R: variable has different number of levels in the node and in the data

I want to use bnlearn for a classification task with Naive Bayes algorithm. I use this data set for my tests. Where 3 variables are continuous ()V2, V4, V10) and others are discrete. As far as I know bnlearn cannot work with continuous variables, so…

Bayesian Netwotk structure learning

Using the bnlearn package I can learn the structure of a BN just by passing my dataset as parameter, for example: bn1 <- blnearn :: hc (dataset) Or must I pass some edges as prior knowledge eg: wl = data.frame (from = c ("A", "B"), to = c ("B",…

Score bic may be used with discrete data only

I have a data frame with all columns in discrete format. I apply the following code to generate a BN using bnlearn package. However I get this error that says "score 'bic' may be used with discrete data only" while essentially my data are discrete!…
