The PC plots of the bicluster identified using noise threshold of 1.2. The expression values of all rows in the four related columns and their difference between the last three columns and the first column are drawn using PC plots in Figures (A) and (B) respectively. In Figures (A) and (B), red color shows rows from the identified bicluster while blue color shows rows from the original dataset. Figures (C) and (D) illustrate the inconsistencies between the identified bicluster and the true bicluster in the four related columns and the column differences respectively. In Figures (C) and (D), the red color indicates rows of the true bicluster that are found by our algorithm while the blue color represents the three missed rows of the true bicluster.
