DB Tsai updated SPARK-7222: --------------------------- Description: Added detailed mathematical derivation of how scaling and LeastSquaresAggregator work. Also refactored the code so the model is compressed based on the storage. We may try compress based on the prediction time. TODO: Add test that fail the test when the correction terms are not correctly computed. (was: Added detailed mathematical derivation of how scaling and LeastSquaresAggregator work.
