Fast and Robust Comparison of Probability Measures in Heterogeneous Spacesstat.ML

Comparing two probability measures supported on heterogeneous spaces is an increasingly important problem in machine learning. Such problems arise when comparing for instance two populations of biological cells, each described with its own set of features, or when looking at families of word embeddings trained across d…
