Data and Model-Driven Selection Using Parallel-Line Groups
(1993-05-01)
A key problem in model-based object recognition is selection, namely, the problem of isolating regions in an image that are likely to come from a single object. This isolation can be either based solely on image data ...
Causal Reconstruction
(1993-02-01)
Causal reconstruction is the task of reading a written causal description of a physical behavior, forming an internal model of the described activity, and demonstrating comprehension through question answering. T his ...
Complexity as a Sclae-Space for the Medial Axis Transform
(1993-01-01)
The medial axis skeleton is a thin line graph that preserves the topology of a region. The skeleton has often been cited as a useful representation for shape description, region interpretation, and object recognition. ...
On the Convergence of Stochastic Iterative Dynamic Programming Algorithms
(1993-08-01)
Recent developments in the area of reinforcement learning have yielded a number of new algorithms for the prediction and control of Markovian environments. These algorithms, including the TD(lambda) algorithm of Sutton ...
Hierarchical Mixtures of Experts and the EM Algorithm
(1993-08-01)
We present a tree-structured architecture for supervised learning. The statistical model underlying the architecture is a hierarchical mixture model in which both the mixture coefficients and the mixture components are ...
A Method for Eliminating Skew Introduced by Non-Uniform Buffer Delay and Wire Lengths in Clock Distribution Trees
(1993-04-01)
The computation of a piecewise smooth function that approximates a finite set of data points is decomposed into two decoupled tasks: first, the computation of the locally smooth models, and hence, the segmentation of ...
Application of Charge Detection to Dynamic Contact Sensing
(1993-03-01)
The manipulation contact forces convey substantial information about the manipulation state. This paper address the fundamental problem of interpreting the force signals without any additional manipulation context. ...
Why Stereo Vision is Not Always About 3D Reconstruction
(1993-07-01)
It is commonly assumed that the goal of stereovision is computing explicit 3D scene reconstructions. We show that very accurate camera calibration is needed to support this, and that such accurate calibration is difficult ...
A Simplified Method for Deriving Equations of Motion For Continuous Systems with Flexible Members
(1993-05-01)
A method is proposed for deriving dynamical equations for systems with both rigid and flexible components. During the derivation, each flexible component of the system is represented by a "surrogate element" which ...
Building Brains for Bodies
(1993-08-01)
We describe a project to capitalize on newly available levels of computational resources in order to understand human cognition. We will build an integrated physical system including vision, sound input and output, and ...
