Interpretable online network dictionary learning for inferring long-range chromatin interactions
Fig 4
A dictionary element, represented as a matrix, consists of both proximal and distal interacting genomic regions.
The elements on the diagonal are not necessarily indexed by adjacent (consecutive) genomic fragments, as explained by the example in the second row. There, off-diagonal long-range interactions in the 9 × 9 matrix are included in a 3 × 3 dictionary element whose diagonal elements are not in consecutive order.
