Modeling second-order boundary perception: A machine learning approach
Fig 11
Second-stage filter weights for one representative observer, JJF, from Experiment 2 (orientation discrimination, Fig 1c, right).
(a) Experiment 2-VAR. Top: Estimated 2-D weight maps averaged over 4 training folds. Bottom: 1-D profiles showing mean weight magnitude (thick lines), averaged over 30 bootstrapped re-samplings. Thin dashed lines show +/- 1 SEM. (b) Same as (a), but for Experiment 2-FIX.
