+The deconvolution module models a prior from cell type-specific expression
+profiles from scRNA-seq to jointly estimate the posterior distribution of cell
+type composition and cell type-specific gene expression from bulk RNA-seq
+expression of tumor samples.  The embedding learning module uses
+@dfn{Expectation-maximization} (EM) to approximate the tumor expression using
+a linear combination of malignant gene programs while conditional on the
+inferred expression and fraction of non-malignant cells estimated by the
+deconvolution module.")
