In all cases the alignments were trimmed to eliminate columns with gaps in more than 50% of the positions.
We also eliminated columns containing a gap.
Therefore, it can be used to identify and eliminate column bottlenecks [9, 10, 11].
where H ˜ el is obtained after processing the sparse aggregated channel matrix H ˜ in the CCN, after eliminating the columns corresponding to the zeros from vec ( W ˜ ).
To obtain the non-negative constraint of solution, the iterative solution is commonly made by eliminating the columns of kernel matrix corresponding to the negative components in the solution or replacing them with large constants.
The effective channel matrix H ¯ k, the effective scale factor α ¯ = diag α ¯ 1 α ¯ 2 … α ¯ n D, and the effective distortion noise d ¯ k = d ¯ 1 k d ¯ 2 k … d ¯ n D k T are obtained by eliminating the columns of H k, the rows of α, and the elements of d k that correspond to the unselected transmit antennas, respectively.
This process of evaluating homology and eliminating questionable columns, known as masking, typically requires time-consuming, skillful, human intervention.
Motif trimming was implemented as in [ 13], by eliminating flanking columns with information content less or equal 0.25 bit from both sides of the individual motifs.
Because the core and perimeter columns carry so much of the load, the designers could eliminate interior columns, with the result that there is more open floor space for the tenants.
Because there were so many load-bearing columns around the perimeter of each building, the engineers could completely eliminate all columns within the office space.
