-----------------------------------
Summary: Accept new values of a nominal attribute
Key: SAMOA-78
URL: https://issues.apache.org/jira/browse/SAMOA-78
Project: SAMOA
Issue Type: New Feature
Components: SAMOA-Instances
Reporter: Maciej Grzenda
As of now, Attribute class assumes all values of a nominal attribute are
defined before stream processing starts. However, in case stream data evolves,
for some attributes the complete list of attribute values may not be known at
the beginning. Hence, apart from declaring a priori all attribute values e.g.
in ARFF header, it sounds reasonable to gradually add new attribute values once
they are encountered in the instances.
