Summary: [ML] Use Double.NaN as default values for missing values in Vector Key: IGNITE-11664 URL: https://issues.apache.org/jira/browse/IGNITE-11664 Project: Ignite Issue Type: Improvement Components: ml Reporter: Alexey Platonov Currently, we use 0.0 value for default values in vectors if a value is missing. But this way contradicts to preprocessors politics where for missing values Double.NaN is using. Moreover, Double.NaN is a more convenient value for missing feature values. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
