From: VIPER: variability-preserving imputation for accurate gene expression recovery in single-cell RNA sequencing studies

Fig. 1

Estimated imputation weights inferred in the two steps of the VIPER method in four data sets. Results are shown for Grun data (a, b), Cell Type data (c, d), Time Course data (e, f), and Shalek data (g, h). Cells with non-zero weights are shown in red. Color labels on top of each heatmap represent different cell subpopulations in that data set. Compared to the pre-selection step (a, c, e, g), the sparsity of non-zero weights further reduced after the estimation step (b, d, f, h) in all data sets
