Figure 5. Visualizing predictive regions of protein sequences.

A visualization of the mismatch neighborhood of the first 7 -mers, selected in all ADTs over 10-fold cross validation, for Picornaviridae, where . Regions containing elements of the mismatch neighborhood of each selected -mer are indicated on the virus proteome, with the grayscale intensity on the plot being inversely proportional to the number of cross-validation folds in which some -mer in that region was selected by Adaboost. Thus, darker spots indicate that some -mer in that part of the proteome was robustly selected by Adaboost. Furthermore, a vertical cluster of dark spots indicate that region, selected by Adaboost to be predictive, is also strongly conserved among viruses sharing a common host type.
