Expand protein features by collecting all pairwise products. Subset selection by correlating the 36k pairs with the 192 proteins. Orthogonalize the features before hands (QR decomposition) to remove some redundancy. Alternatively use Randomized PCA. This can be expanded to other pairwise protein interactions.
