+Generalizable representations should also be robust in cross-study validation, transfering across datasets of related biological
 contexts, while representations of noise will not. In addition, we have found that combining
 multiple representations can better capture biological processes across scales
 [@doi:10.1016/j.cels.2017.06.003], and that representations across scales capture distinct,
