    • A Unified Framework for Regularization Networks and Support Vector Machines 

      Evgeniou, Theodoros; Pontil, Massimiliano; Poggio, Tomaso (1999-03-01)
      Regularization Networks and Support Vector Machines are techniques for solving certain problems of learning from examples -- in particular the regression problem of approximating a multivariate function from sparse ...

    • The Unsupervised Acquisition of a Lexicon from Continuous Speech 

      Marcken, Carl de (1996-01-18)
      We present an unsupervised learning algorithm that acquires a natural-language lexicon from raw speech. The algorithm is based on the optimal encoding of symbol sequences in an MDL framework, and uses a hierarchical ...

    • Vector-Based Integration of Local and Long-Range Information in Visual Cortex 

      Somers, David C.; Todorov, Emanuel V.; Siapas, Athanassios G.; Sur, Mriganka (1996-01-18)
      Integration of inputs by cortical neurons provides the basis for the complex information processing performed in the cerebral cortex. Here, we propose a new analytic framework for understanding integration within ...

    • Verb Classes and Alternations in Bangla, German, English, and Korean 

      Jones, Douglas A.; Berwick, Robert C.; Cho, Franklin; Khan, Zeeshan; Kohl, Karen T.; e.a. (1996-05-06)
      In this report, we investigate the relationship between the semantic and syntactic properties of verbs. Our work is based on the English Verb Classes and Alternations of (Levin, 1993). We explore how these classes are ...

    • A View on Dyslexia 

      Geiger, Gad; Lettvin, Jerome Y. (1997-06-01)
      We describe here, briefly, a perceptual non-reading measure which reliably distinguishes between dyslexic persons and ordinary readers. More importantly, we describe a regimen of practice with which dyslexics learn a ...

    • View-Based Strategies for 3D Object Recognition 

      Sinha, Pawan; Poggio, Tomaso (1995-04-21)
      A persistent issue of debate in the area of 3D object recognition concerns the nature of the experientially acquired object models in the primate visual system. One prominent proposal in this regard has expounded the ...

    • Visual Recognition and Categorization on the Basis of Similarities to Multiple Class Prototypes 

      Edelman, Shimon; Duvdevani-Bar, Sharon (1997-09-01)
      To recognize a previously seen object, the visual system must overcome the variability in the object's appearance caused by factors such as illumination and pose. Developments in computer vision suggest that it may be ...

    • Visual Segmentation without Classification in a Model of the Primary Visual Cortex 

      Li, Zhaoping (1997-08-01)
      Stimuli outside classical receptive fields significantly influence the neurons' activities in primary visual cortex. We propose that such contextual influences are used to segment regions by detecting the breakdown of ...

    • Visual Speech Synthesis by Morphing Visemes 

      Ezzat, Tony; Poggio, Tomaso (1999-05-01)
      We present MikeTalk, a text-to-audiovisual speech synthesizer which converts input text into an audiovisual speech stream. MikeTalk is built using visemes, which are a small set of images spanning a large range of mouth ...
