Predictable stimulus statistics improve an observer's ability to discriminate between face views based on the population representation. A: performance of an SVM classifier in decoding viewing angle, using the responses of all 131 IT neurons in a sliding 100-ms window. Gray lines and colored squares indicate classifier performance using the entire visual response (70–320 ms after stimulus onset); overall performance is higher in the face condition (red) than in the mixed condition (blue). B: performance of the classifier as a function of the number of randomly selected neurons used for decoding, for the face condition (red) and the mixed condition (blue).
