Re: Problem with structure learning

Naive Bayes algorithm needs to know which variable in your dataset is a class variable. In SMILE.NET you can specify the class variable by setting the NaiveBayes.ClassVariableId property. The class variable identifier should be matched by one of the variables in the dataset passed as a parameter to ...

Re: Problem with structure learning

I have problem with structure bayesian network learning using Naive Bayes algorithm. When I try to learn my network - .NET throws SmileException with error code -1. How did you select the class variable? Using the opportunity I'd like to draw attention to the fact that Bayesian Search algorithm is ...

Re: Leading S in text

The leading S is added by GeNIe when you learn network from a data file, and the value in the data column contains non-alphanumeric characters and underscores, or starts with non-letter. I believe your data file had a NATURE column with "aceration open wound" value. The spaces between the words caus...

Re: cross validation

Is there a possibility to view the individual results of each fold of a K-fold CV? No, that's not possible. Also, how is the final result for K-fold CV calculated? average of K folds? min of the K folds? max of the K folds? We create a single confusion matrix over all folds (because each record in ...

Re: piechart

We'll add this feature in the next service release. Note that when you use a Copy command in the chart window, GeNIe copies the bitmap but also tab separated name/count pairs as text. You can subsequently paste such text into a program like Excel or Google Sheets and use its graphing features to obt...

Re: Sample code (Python preferred) for Dynamic Bayesian Network

conditional probabilities in nodes in slice t+1 depend only on conditional probabilities in nodes in the same slice and slice t. Your temporal arcs have order 1, therefore your CPTs in t+1 are conditioned on nodes in t+1 and t. However, the calculated posterior probabilities depend on the entire un...

Re: Training with a completely hidden node

EM in GeNIe does not require that every node has an associated data column. GeNIe will attempt to match as many node/column pairs as possible, based on the identifiers. If V in the dataset has only missing values, either remove the column V, or drag the V node to the left list to ensure it is not as...

Re: SMILE INITERR OE

Is there anything else I was supposed to do to update my licence and get it working again?
No, that should be enough. Make sure you've recompiled all your sources and your tool actually uses new binaries (with new license information).

Re: Urgent - errors in LEAK column

We'll be glad to help, but please be more specific. Can you describe a repeatable sequence of steps, or post a network file containing a noisy node causing issues you've described in your original post?
