Relationship between the facility location objective function and evaluation metrics. Each dot corresponds to one of 40 randomly chosen panels. Pink triangles indicate results from maximizing the SSA-future facility location function; red diamonds indicate the panel of most-frequently performed assay types (Additional file 1: Table S5). These results were computed in GM12878, using panels of four assay types. Assay imputation, functional element prediction, and annotation-based evaluation. SSA submodular selection of assays
