    "title": "Modeling the Object Recognition Pathway: A Deep Hierarchical Model Using\nGnostic Fields",
    "subtitle": null,
    "abstract": "To recognize objects, the human visual system processes information\nthrough a network of hierarchically organized brain\nregions. Many neurocomputational models have modeled this\nhierarchical structure, but they have often used hand-crafted\nfeatures to model early visual areas. According to the linear efficient\ncoding hypothesis, the goal of the early visual pathway\nis to capture the statistical structure of sensory stimuli, removing\nredundancy, and factoring the input into independent features.\nIn this work, we use a hierarchical Independent Components\nAnalysis (ICA) algorithm to automatically learn the visual\nfeatures that account for early visual cortex. We then continue\nmodeling the object recognition pathway using Gnostic\nFields, a theory for how the brain does object categorization, in\nwhich brain regions devoted to classifying mutually-exclusive\ncategories exist near the top of sensory processing hierarchies.\nThe whole biologically-inspired model not only allows us to\ndevelop representations similar to those in primary visual cortex,\nbut also to perform well on standard computer vision object\nrecognition benchmarks.",
