Figure 1. Shows the double-context task which has four stimuli A, B, C, and D in one of four contexts 1, 2, 3, or 4.

(A) Mapping between stimuli and quadrant context onto responses X or Y, which gives 16 stimulus-context combinations or data points. (B) Matrix with binary, training data where stimuli and quadrant context are concatenated into one input vector with eight dimensions and X and Y into an output vector with two dimensions.
