Efficient discovery of frequently co-occurring mutations in a sequence database with matrix factorization

Example clustered heat-map of a H matrix for r = 12.
The X-axis is an arbitrarily assigned number to each factor, depending on its position in the matrix (i.e 0-11). The Y-axis is the remaining residue positions after removing all-zero rows, demonstrating only the H matrix rows which had CMPs.
