Alexey Zinoviev updated IGNITE-11664: ------------------------------------- Fix Version/s: 2.9 > [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 Zinoviev > Assignee: Alexey Zinoviev > Priority: Major > Labels: stability > Fix For: 2.9 > > > 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 (v8.3.4#803005)
