Classification of binocular disparities of a three-layered neural network with inputs of hybrid-type disparity detectors

Abstract (in Japanese) (See Japanese page) 
(in English) Binocular complex neurons in the primary visual cortex (V1) are successfully modeled as “hybrid-type” disparity-energy units whose receptive fields (RFs) contain both phase and position differences between the eyes. To understand the mechanisms for decoding stimulus binocular disparities using signals of these units, we constructed a three-layered neural network that included the hybrid-type units for the input layer and learned to classify binocular disparities (-0.5 to 0.5 degrees in 0.1 degree steps) in the random-dot stereograms. After learning, the hybrid-type network correctly (> 95%) classified the stimulus binocular disparities. Although the range of RF positional differences of the hybrid-type units (-0.7°~ 0.7°) is larger than that of the stimulus binocular disparities, nearly all of the middle-layer units are most strongly connected with the input-layer units whose RF phase difference is the maximum used in this experiment. The present results indicate that, for correct classification, the range of binocular disparities coded by the input layer should be considerably larger than that of stimulus binocular disparity. This may be one factor for the middle layer units being strongly connected with the hybrid-type units with large RF phase differences.
