Kernels of learning : tracking the emergence of visual recognition through multivariate approaches (Massachusetts Institute of Technology, 2011)The visual system is a dynamic entity whose response properties depend on context and experience. In this thesis, I examine how the brain changes as we learn to see - what changes occur during the onset of recognition, in ...

(Massachusetts Institute of Technology, 2008)Within the metaphor of the "mind as a computation device" that dominates cognitive science, understanding human cognition means understanding learnability not only what (and how) the brain learns, but also what data is ...
-
(Massachusetts Institute of Technology, 2007)The effects of observed object motion on object perception are examined in two sets of studies. The first section of the thesis provides a thorough examination of various untested aspects of the basic "temporal association" ...
-
(Massachusetts Institute of Technology, 2006)In this thesis, I describe a quantitative model that accounts for the circuits and computations of the feedforward path of the ventral stream of visual cortex. This model is consistent with a general theory of visual ...
-
(Massachusetts Institute of Technology, 2011)This thesis develops the hypothesis that key aspects of learning and development can be understood as rational statistical inferences over a compositionally structured representation system, a language of thought (LOT) ...
-
(Massachusetts Institute of Technology, 2009)In this thesis I present new contributions to the fields of neuroscience and computer science. The neuroscientific contribution is a new technique for automatically reconstructing complete neural networks from densely ...
-
(Massachusetts Institute of Technology, 2012)Some of the biggest achievements in our lives are made even before we learn to tie our shoes. Within a few years of life, we master a language, acquire cultural norms, and develop naïve, yet rich, abstract, coherent theories ...

(Massachusetts Institute of Technology, 2010)One of the great puzzles of vision science is how, over the course of development, the complex visual array comprising many regions of different colors and luminances is transformed into a sophisticated and meaningful ...
-
(Massachusetts Institute of Technology, 2008)Perturbations of sensory experience in young animals are known to cause lasting changes in adult brain function. For example, monocular visual deprivation by lid closure (MC) leads to a loss of cortical responsiveness of ...

(Massachusetts Institute of Technology, 2010)We present an approach to solving computer vision problems in which the goal is to produce a high-dimensional, pixel-based interpretation of some aspect of the underlying structure of an image. Such tasks have traditionally ...

(Massachusetts Institute of Technology, 2004)One of the fundamental issues in cognitive science is the problem of grounding concepts in the perceptual world. In this thesis, I present a computational theory for how spatial relations are grounded in the perceptual ...
-
(Massachusetts Institute of Technology, 2009)What do words and phrases mean? How do we infer their meaning in a given context? How do we know which sets of words have sensible meanings when combined, as opposed to being nonsense? As language learners and speakers, ...
-
(Massachusetts Institute of Technology, 2011)Ocular dominance (OD) plasticity is a classic example of bidirectional experience-dependent plasticity in the primary visual cortex. This form of plasticity is most robust during early postnatal development (termed the ...
