----------------------------------------
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.
