Table 1.
Radiomic sequence lengths and the modeling accuracies over generations. “ANF" stands for average number of filters in the sequencer and “RSL” column represents the average length of the radiomic sequence at each generation. Since the numbers are averaged over 10 folds of evaluation, they are reported with one floating point precision. As seen while the radiomic sequences become more compact over generations, the modeling accuracy, sensitivity, and specificity are increasing.
