  • Fast Learning by Bounding Likelihoods in Sigmoid Type Belief Networks 

    Unknown author (1996-02-09)
    Sigmoid type belief networks, a class of probabilistic neural networks, provide a natural framework for compactly representing probabilistic information in a variety of unsupervised and supervised learning problems. ...

  • General Purpose Parallel Computation on a DNA Substrate 

    Unknown author (1996-12-01)
    In this paper I describe and extend a new DNA computing paradigm introduced in Blumberg for building massively parallel machines in the DNA-computing models described by Adelman, Cai et. al., and Liu et. al. Employing ...

  • 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 ...

  • Internet Fish 

    Unknown author (1996-08-01)
    I have invented "Internet Fish," a novel class of resource-discovery tools designed to help users extract useful information from the Internet. Internet Fish (IFish) are semi-autonomous, persistent information brokers; ...

  • Learning and Example Selection for Object and Pattern Detection 

    Unknown author (1996-03-13)
    This thesis presents a learning based approach for detecting classes of objects and patterns with variable image appearance but highly predictable image boundaries. It consists of two parts. In part one, we introduce our ...

  • Learning from Incomplete Data 

    Unknown author (1995-01-24)
    Real-world learning tasks often involve high-dimensional data sets with complex patterns of missing features. In this paper we review the problem of learning from incomplete data from two statistical perspectives---the ...

  • 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 ...

  • Lens Distortion Calibration Using Point Correspondences 

    Unknown author (1996-12-01)
    This paper describes a new method for lens distortion calibration using only point correspondences in multiple views, without the need to know either the 3D location of the points or the camera locations. The standard ...

  • Model-Based Matching by Linear Combinations of Prototypes 

    Unknown author (1996-12-01)
    We describe a method for modeling object classes (such as faces) using 2D example images and an algorithm for matching a model to a novel image. The object class models are "learned'' from example images that we call ...

  • Model-Based Matching of Line Drawings by Linear Combinations of Prototypes 

    Unknown author (1996-01-18)
    We describe a technique for finding pixelwise correspondences between two images by using models of objects of the same class to guide the search. The object models are 'learned' from example images (also called ...

  • Neural Networks 

    Unknown author (1996-03-13)
    We present an overview of current research on artificial neural networks, emphasizing a statistical perspective. We view neural networks as parameterized graphs that make probabilistic assumptions about data, and view ...

  • 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 Support Vector Machines Degeneracy 

    Unknown author (1999-08-11)
    When training Support Vector Machines (SVMs) over non-separable data sets, one sets the threshold $b$ using any dual cost coefficient that is strictly between the bounds of $0$ and $C$. We show that there exist SVM ...

  • 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 ...

  • Object Detection in Images by Components 

    Unknown author (1999-08-11)
    In this paper we present a component based person detection system that is capable of detecting frontal, rear and near side views of people, and partially occluded persons in cluttered scenes. The framework that is ...

  • Organizing a Global Coordinate System from Local Information on an Amorphous Computer 

    Unknown author (1999-08-29)
    This paper demonstrates that it is possible to generate a reasonably accurate coordinate system on randomly distributed processors, using only local information and local communication. By coordinate systems we imply ...

  • Parallel Function Application on a DNA Substrate 

    Unknown author (1996-12-01)
    In this paper I present a new model that employs a biological (specifically DNA -based) substrate for performing computation. Specifically, I describe strategies for performing parallel function application in the ...

  • Pose-Invariant Face Recognition Using Real and Virtual Views 

    Unknown author (1996-03-28)
    The problem of automatic face recognition is to visually identify a person in an input image. This task is performed by matching the input face against the faces of known people in a database of faces. Most existing ...
