Rk-means: Fast Clustering for Relational Data · RelationalAI

This work expanded the class of ML models one can train relationally to some
unsupervised models.

and Statistics (AISTATS ‘20).
Conventional machine learning algorithms cannot be applied until a data matrix
is available to process. When the data matrix needs to be obtained from a
relational database via a feature extraction query, the computation cost can be
prohibitive, as the data matrix may be (much) larger than the total input
relation size. This paper introduces Rk-means, or relationalk-means algorithm,
for clustering relational data tuples without having to access the full data
matrix.
