MIT SchMUSE: Class-Based Remote Delegation in a Capricious Distributed Environment
(1993-02-01)MIT SchMUSE (pronounced "shmooz") is a concurrent, distributed, delegation-based object-oriented interactive environment with persistent storage. It is designed to run in a "capricious" network environment, where servers ...

Three Cuts for Accelerated Interval Propagation
(1995-05-01)This paper addresses the problem of nonlinear multivariate root finding. In an earlier paper we described a system called Newton which finds roots of systems of nonlinear equations using refinements of interval methods. ...

Vectorizing Face Images by Interpreting Shape and Texture Computations
(1995-09-01)The correspondence problem in computer vision is basically a matching task between two or more sets of features. In this paper, we introduce a vectorized image representation, which is a feature-based representation where ...

Face Recognition from One Example View
(1995-09-01)If we are provided a face database with only one example view per person, is it possible to recognize new views of them under a variety of different poses, especially views rotated in depth from the original example ...

Comparison Between Subsonic Flow Simulation and Physical Measurements of Flue Pipes
(1995-04-01)Direct simulations of wind musical instruments using the compressible Navier Stokes equations have recently become possible through the use of parallel computing and through developments in numerical methods. As a first ...

Aeroacoustics on Non-Dedicated Workstations
(1995-04-01)The simulation of subsonic aeroacoustic problems such as the flow-generated sound of wind instruments is well suited for parallel computing on a cluster of non-dedicated workstations. Simulations are demonstrated which ...

Spatial Reference Frames for Object Recognition: Tuning for Rotations in Depth
(1995-03-01)The inferior temporal cortex (IT) of monkeys is thought to play an essential role in visual object recognition. Inferotemporal neurons are known to respond to complex visual stimuli, including patterns like faces, ...
-
The M-Machine Multicomputer
(1995-03-01)The M-Machine is an experimental multicomputer being developed to test architectural concepts motivated by the constraints of modern semiconductor technology and the demands of programming systems. The M- Machine computing ...

Linear Object Classes and Image Synthesis from a Single Example Image
(1995-03-01)The need to generate new views of a 3D object from a single real image arises in several fields, including graphics and object recognition. While the traditional approach relies on the use of 3D models, we have recently ...

A Note of Zipf's Law, Natural Languages, and Noncoding DNA Regions
(1995-03-01)In Phys. Rev. Letters (73:2), Mantegna et al. conclude on the basis of Zipf rank frequency data that noncoding DNA sequence regions are more like natural languages than coding regions. We argue on the contrary that an ...

Estimation of Pose and Illuminant Direction for Face Processing
(1994-11-01)In this paper three problems related to the analysis of facial images are addressed: the illuminant direction, the compensation of illumination effects and, finally, the recovery of the pose of the face, restricted to ...

Towards an Example-Based Image Compression Architecture for Video-Conferencing
(1994-06-01)This paper consists of two major parts. First, we present the outline of a simple approach to very-low bandwidth video-conferencing system relying on an example-based hierarchical image compression scheme. In particular, ...

Neural Network Exploration Using Optimal Experiment Design
(1994-06-01)We consider the question "How should one act when the only goal is to learn as much as possible?" Building on the theoretical results of Fedorov [1972] and MacKay [1992], we apply techniques from Optimal Experiment ...

Relative Affine Structure: Canonical Model for 3D from 2D Geometry and Applications
(1994-06-01)We propose an affine framework for perspective views, captured by a single extremely simple equation based on a viewer-centered invariant we call "relative affine structure". Via a number of corollaries of our main ...

Partial Evaluation for Scientific Computing: The Supercomputer Toolkit Experience
(1994-05-01)We describe the key role played by partial evaluation in the Supercomputer Toolkit, a parallel computing system for scientific applications that effectively exploits the vast amount of parallelism exposed by partial ...
-
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 ...
-
Piecemeal Learning of an Unknown Environment
(1994-03-01)We introduce a new learning problem: learning a graph by piecemeal search, in which the learner must return every so often to its starting point (for refueling, say). We present two linear-time piecemeal-search ...

Viewer-Centered Object Recognition in Monkeys
(1994-04-01)How does the brain recognize three-dimensional objects? We trained monkeys to recognize computer rendered objects presented from an arbitrarily chosen training view, and subsequently tested their ability to generalize ...
-
View-Based Models of 3D Object Recognition and Class-Specific Invariances
(1994-04-01)This paper describes the main features of a view-based model of object recognition. The model tries to capture general properties to be expected in a biological architecture for object recognition. The basic module is a ...

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 ...
