Recognition by Prototypes
(1992-12-01)
A scheme for recognizing 3D objects from single 2D images is introduced. The scheme proceeds in two stages. In the first stage, the categorization stage, the image is compared to prototype objects. For each prototype, ...
Convergence Results for the EM Approach to Mixtures of Experts Architectures
(1993-11-01)
The Expectation-Maximization (EM) algorithm is an iterative approach to maximum likelihood parameter estimation. Jordan and Jacobs (1993) recently proposed an EM algorithm for the mixture of experts architecture of ...
Formalizing Triggers: A Learning Model for Finite Spaces
(1993-11-01)
In a recent seminal paper, Gibson and Wexler (1993) take important steps to formalizing the notion of language learning in a (finite) space whose grammars are characterized by a finite number of parameters. They introduce ...
Algebraic Functions For Recognition
(1994-01-01)
In the general case, a trilinear relationship between three perspective views is shown to exist. The trilinearity result is shown to be of much practical use in visual recognition by alignment --- yielding a direct method ...
Exploiting the Parallelism Exposed by Partial Evaluation
(1993-04-01)
We describe an approach to parallel compilation that seeks to harness the vast amount of fine-grain parallelism that is exposed through partial evaluation of numerically-intensive scientific programs. We have constructed ...
Garbage Collection is Fast, But a Stack is Faster
(1994-03-01)
Prompted by claims that garbage collection can outperform stack allocation when sufficient physical memory is available, we present a careful analysis and set of cross-architecture measurements comparing these two approaches ...
Analytical Representation of Contours
(1992-10-01)
The interpretation and recognition of noisy contours, such as silhouettes, have proven to be difficult. One obstacle to the solution of these problems has been the lack of a robust representation for contours. The contour ...
Face Recognition Under Varying Pose
(1993-12-01)
While researchers in computer vision and pattern recognition have worked on automatic techniques for recognizing faces for the last 20 years, most systems specialize on frontal views of the face. We present a face recognizer ...
Parallel Simulation of Subsonic Fluid Dynamics on a Cluster of Workstations
(1995-12-01)
An effective approach of simulating fluid dynamics on a cluster of non- dedicated workstations is presented. The approach uses local interaction algorithms, small communication capacity, and automatic migration of parallel ...
On the Relationship Between Generalization Error, Hypothesis Complexity, and Sample Complexity for Radial Basis Functions
(1994-02-01)
In this paper, we bound the generalization error of a class of Radial Basis Function networks, for certain well defined function learning tasks, in terms of the number of parameters and number of examples. We show ...
