Dimensionality Reduction for Categorical Data

no code implementations1 Dec 2021 Debajyoti Bera, Rameshwar Pratap, Bhisham Dev Verma

We show that FSketch is significantly faster, and the accuracy obtained by using its sketches are among the top for the standard unsupervised tasks of RMSE, clustering and similarity search.
