Figure S2. Comparison of
decoding accuracy levels for three different classifiers for basic
sample-stimulus category information, for ITC (A), and PFC (B).
The magenta line is the classification accuracy obtained using
correlation coefficient classifier, the orange line is the
classification accuracy obtained using support vector machine (SVM) and
the green line is the classification accuracy obtained using a Poisson
Naïve Bayes classifier. As can be seen, while the mean accuracy
level varies depending on which classifier is used, the trends over
time remain the same, which gives us confidence that the conclusions we
draw in this paper are not dependent on the classifier used since
always compare results using the same classifier through the
paper. It should be noted that the regularization parameter was
not optimized for the SVM which could account for its overall lower
accuracy level.
