But both are related to statistics over data sets. This is why I combined them both in one. If you're wondering, there is a JIRA for the column wise statistics as well. [FLINK-2379]. Unless it is absolutely necessary, I'd like to keep them both in one. > Add methods to evaluate field wise statistics over DataSet of vectors. > ---------------------------------------------------------------------- > > Key: FLINK-2379 > URL: https://issues.apache.org/jira/browse/FLINK-2379 > Project: Flink > Issue Type: New Feature > Components: Machine Learning Library > Reporter: Sachin Goel > Assignee: Sachin Goel > > Design methods to evaluate statistics over dataset of vectors. > For continuous fields, Minimum, maximum, mean, variance. > For discrete fields, Class counts, Entropy, Gini Impurity. > Further statistical measures can also be supported. For example, correlation between two series, computing the covariance matrix, etc. > [These are currently the things Spark supports.] -- This message was sent by Atlassian JIRA (v6.3.4#6332)
