Example responses to binocular sine-gratings for 25 individual complex models learned using ISA.

The models consist of two linear subunits combined in a sum of squares manner. The phase of the left view sine-grating is shown on the horizontal axis, the right view phase is shown on the horizontal axis. The phases in both views vary between −π and π. 100 samples were taken within this range for each view resulting in a 100x100 response map. Locations of equal disparity lie on diagonal lines, locations of zero-disparity are shown as a black line.
