  • Comparing Support Vector Machines with Gaussian Kernels to Radial Basis Function Classifiers 

    Unknown author (1996-12-01)
    The Support Vector (SV) machine is a novel type of learning machine, based on statistical learning theory, which contains polynomial classifiers, neural networks, and radial basis function (RBF) networks as special ...

  • Image-Based View Synthesis 

    Unknown author (1997-01-01)
    We present a new method for rendering novel images of flexible 3D objects from a small number of example images in correspondence. The strength of the method is the ability to synthesize images whose viewing position ...

  • A Detailed Look at Scale and Translation Invariance in a Hierarchical Neural Model of Visual Object Recognition 

    Unknown author (2002-08-01)
    The HMAX model has recently been proposed by Riesenhuber & Poggio as a hierarchical model of position- and size-invariant object recognition in visual cortex. It has also turned out to model successfully a number of ...

  • A View on Dyslexia 

    Unknown author (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 ...

  • Triangulation by Continuous Embedding 

    Unknown author (1997-03-01)
    When triangulating a belief network we aim to obtain a junction tree of minimum state space. Searching for the optimal triangulation can be cast as a search over all the permutations of the network's vaeriables. Our ...

  • Pre-Attentive Segmentation in the Primary Visual Cortex 

    Unknown author (1998-06-30)
    Stimuli outside classical receptive fields have been shown to exert significant influence over the activities of neurons in primary visual cortexWe propose that contextual influences are used for pre-attentive visual ...

  • Information Dissemination and Aggregation in Asset Markets with Simple Intelligent Traders 

    Unknown author (1998-09-01)
    Various studies of asset markets have shown that traders are capable of learning and transmitting information through prices in many situations. In this paper we replace human traders with intelligent software agents ...

  • A Trainable Object Detection System: Car Detection in Static Images 

    Unknown author (1999-10-13)
    This paper describes a general, trainable architecture for object detection that has previously been applied to face and peoplesdetection with a new application to car detection in static images. Our technique is a ...

  • Learning-Based Approach to Real Time Tracking and Analysis of Faces 

    Unknown author (1999-09-23)
    This paper describes a trainable system capable of tracking faces and facialsfeatures like eyes and nostrils and estimating basic mouth features such as sdegrees of openness and smile in real time. In developing this ...

  • Rotation Invariant Real-time Face Detection and Recognition System 

    Unknown author (2001-05-31)
    In this report, a face recognition system that is capable of detecting and recognizing frontal and rotated faces was developed. Two face recognition methods focusing on the aspect of pose invariance are presented and ...

  • A Note on Object Class Representation and Categorical Perception 

    Unknown author (1999-12-17)
    We present a novel scheme ("Categorical Basis Functions", CBF) for object class representation in the brain and contrast it to the "Chorus of Prototypes" scheme recently proposed by Edelman. The power and flexibility ...

  • A Note on the Generalization Performance of Kernel Classifiers with Margin 

    Unknown author (2000-05-01)
    We present distribution independent bounds on the generalization misclassification performance of a family of kernel classifiers with margin. Support Vector Machine classifiers (SVM) stem out of this class of machines. The ...

  • Building Grounded Abstractions for Artificial Intelligence Programming 

    Unknown author (2004-06-16)
    Most Artificial Intelligence (AI) work can be characterized as either ``high-level'' (e.g., logical, symbolic) or ``low-level'' (e.g., connectionist networks, behavior-based robotics). Each approach suffers from particular ...

  • BioJADE: A Design and Simulation Tool for Synthetic Biological Systems 

    Unknown author (2004-05-28)
    The next generations of both biological engineering and computer engineering demand that control be exerted at the molecular level. Creating, characterizing and controlling synthetic biological systems may provide us ...

  • Learning Commonsense Categorical Knowledge in a Thread Memory System 

    Unknown author (2004-05-18)
    If we are to understand how we can build machines capable of broad purpose learning and reasoning, we must first aim to build systems that can represent, acquire, and reason about the kinds of commonsense knowledge that ...

  • Generative Temporal Planning with Complex Processes 

    Unknown author (2004-05-18)
    Autonomous vehicles are increasingly being used in mission-critical applications, and robust methods are needed for controlling these inherently unreliable and complex systems. This thesis advocates the use of model-based ...

  • Fluorescence Assay for Polymerase Arrival Rates 

    Unknown author (2003-08-31)
    To engineer complex synthetic biological systems will require modular design, assembly, and characterization strategies. The RNA polymerase arrival rate (PAR) is defined to be the rate that RNA polymerases arrive at a ...

  • Representation and Detection of Shapes in Images 

    Unknown author (2003-08-08)
    We present a set of techniques that can be used to represent and detect shapes in images. Our methods revolve around a particular shape representation based on the description of objects using triangulated polygons. This ...

  • Compact Representations for Fast Nonrigid Registration of Medical Images
