Enterprise data management with low-rank topic models
Jiahao Chen

How can enterprises create a catalogue of what data they have, given only a few labels and access to physical data layouts and other metadata? I show how to extend GeneralizedLowRankModels.jl to generate topic models that can be used for semisupervised learning tasks like extrapolating from known labels, evaluating possible errors in existing labels, and predicting missing metadata.
