Figure 4.2: Non-traditional Laplacian dimension reduction. Results of the Laplacian dimension reduction method for the Bhattacharjee data, showing ProbeSet correlation by sample class. The direction of change of the ProbeSet is indicated both by color and arrow. Latent structure is observed in all three groups. Top to bottom the graphs are from data matrices that started with values derived from the RMA, dCHIP, and log-transformed BaFL values. The structure observed via the Laplacian dimension reduction method was assessed across both datasets to see if the structure was consistent in both. There was significant preservation of the structure in the case of the BaFL interpreted data, but in the RMA and dCHIP data sets the structure was lost, as presented in Figure 4.3. Statistical discordance indicates those ProbeSets which were found to be significantly expressed in only one of the datasets and applies only to the RMA and dCHIP produced values for these 325 ProbeSets. Pattern discordance, on the other hand, indicates ProbeSets which demonstrated differential expression in both dataset, but the direction of change was different per dataset. While there does appear to be some latent structure 98
for the RMA and dCHIP interpretations, the separation is not complete as it is for the BaFL results. Since, the latent structure that is presented by the BaFL interpretation could be an artifact of normalizing the SVD matrix to the first ProbeSet, permutations were performed upon the ProbeSet ordering. Permuting the gene order did not affect the latent structure that is observed, although minor variations of the structure were found. These results are presented in the Appendix E. Figure 4.3: Cross dataset latent Laplacian structure. Results of the Laplacian dimension reduction method on both the Bhattacharjee and Stearman data for ProbeSets, based upon sample correlations. These graphs compare the 1 st Laplacian dimension of both datasets, Stearman on the y axis and Bhattacharjee on the x axis. The direction of change is indicated by the color and direction of the arrow; there are four colors to account for incongruencies in the direction of change between the datasets, as noted in the text. Latent Structure is apparent in the third graph of the BaFL interpreted data. From top to bottom: RMA, dCHIP, and BaFL produced values were used in the original data matrices. 99
