dehasi opened a new pull request #6567: IGNITE-9978 Implement Compound Naive Bayes classifier
URL: https://github.com/apache/ignite/pull/6567
 
 
   Compound Naive Bayes over Gaussian and Discrete models.
   
   To implement Compound Naive Bayes,  Gaussian and Discrete models were updated:
   * A method `setFeatureIdsToSkip(Collection<Integer> featureIdsToSkip)`  was added
to Gaussian and Discrete trainers. The method accepts a collection with feature ids which
should be skipped in a trainer. 
   
   * A method `double[] probabilityPowers(Vector vector)` was added to Gaussian and Discrete
models.  The method returns an array where the index is a label index and value is a probability
power of being this label.
   
   @zaleslaw @ybabak @avplatonov @dmitrievanthony could you take a look?
