The median network results after applying supervised SCCA [15] to 5 simulations under each simulation setting. Supervised SCCA was applied to the simulations before filtering and after filtering based on SuMO-Fil, low means, and low variance. Under the simulations with 45305 total features, SuMO-Fil at minimum maintained sensitivity (while improving sensitivity under weak signal strength) and increased specificity by reducing the amount of noise in the network selections. SuMO-Fil also maintained or increased specificity under simulations with 25305 total features, although sensitivity was decreased under both SuMO-Fil and low mean filters with moderate signal strength. SuMO-Fil maintained or increased sensitivity under simulations with 15305 total features, although specificity was decreased under moderate network signal. Filtering based on low variance often decreased sensitivity to 0 while drastically increasing the number of noise selected and increasing run times. Performing supervised SCCA after SuMO-Fil produced the shortest run times under most simulation settings.
