Abstract: A set of data elements is received. For each feature of a set of features, a corresponding reference distribution for the set of data elements is determined. For each feature of the set of features, one or more corresponding subset distributions for one or more subsets sampled from the set of data elements are determined. For each feature of the set of features, the corresponding reference distribution is compared with each of the one or more corresponding subset distributions to determine a corresponding distribution of divergences. At least the determined distributions of divergences for the set of features are provided for use in automated data analysis.

Abstract: One or more events of a data stream are received. For each feature of a set of features, the one or more events are used to update a corresponding distribution of data from the data stream. For each feature of the set of features, the corresponding updated distribution and a corresponding reference distribution are used to determine a corresponding divergence value. For each feature of the set of features, the corresponding determined divergence value and a corresponding distribution of divergences are used to determine a corresponding statistical value. Using the statistical values each corresponding to a different feature of the set of features, a statistical analysis is performed to determine a result associated with a likelihood of data drift detection.
