Fig. 2: Procedure for classification analysis on relative numerosity coding.
From: Hierarchical representations of relative numerical magnitudes in the human frontoparietal cortex
We trained a four-class classifier using one of the three numerosity sets and then tested its ability to decode the relative position of numerosity in the other two numerosity sets. This procedure was repeated for each possible combination of stimulus sets. Note that only one fold of this procedure is illustrated here for clarity. XS, extra small; S, small; L, large; XL, extra large.
