Illustration of a pooling scheme example. a 12 samples denoted by the letters A to L are mixed in 6 pools as shown in the bipartite graph where each sample in included in 2 pools. b The pooling scheme is represented by the pooling matrix Φ. Φ is a binary adjacency matrix where the columns represent the sample vertices, and rows represent the pool vertices. Φ(i,j) therefore indicates that jth sample is included in the ith pool. The support sets of the rows are represented by \(\Omega ^{row}_{i}\) sets, whereas the support sets of the columns are represented by \(\Omega ^{col}_{j}\) sets
