The addition of a third attribute does not meaningfully improve the performance of the classifier: the most informative two attribute and three attribute rules both have a cross validation accuracy of 72%.
Decoding accuracy in Figure 3b was estimated for each condition by leave-one-out cross-validation, combining the arithmetic mean [Alexandre et al., 2001] of nine classifiers using the most informative time-frequency bin from each subject (nine bins indicated as white ticks in Fig. 3a).
Only Classifiers built using the most informative amino acid properties for a given class are shown.
The most informative features (according to information gain [ 32]) were the nucleotides in the NAGNAG and its immediate vicinity, and even a relatively simple classifier like the Naïve Bayes classifier could match the more sophisticated Bayesian network and Support vector machine.
The most informative sites used in the proliferation module classifier are derived from EGFR and SYK (Spleen Tyrosine Kinase).
Right panel shows classification accuracy for the classifiers using 1 3 of the most informative spatial dimensions (Diedrichsen et al., 2013 ).
If the patterns only differ in the intensity scaling of a common pattern, then best classification accuracy should be achieved with a classifier that uses only the most informative pattern component of the training data set.
First, it shows that the changes in classification accuracy were not due to larger between-sequence differences, or lower within-sequence variability, of a single behavioral factor otherwise the difference would have been apparent using a classifier that uses only the most informative spatial pattern component.
We observe that the computationally expensive step of computing the fusion transcript reading frame is justified in the eyes of the classifier, as it is the single most informative feature.
Besides the best performing grammars, classifiers trained for properties, which were not the most informative for a given class, e.g. van der Waals volume for classes 1 and 4, and accessibility for classes 2 and 3 obtained average A U C R O C below 0.50.
