Visual Speech Synthesis by Morphing Visemes
(1999-05-01)
We present MikeTalk, a text-to-audiovisual speech synthesizer which converts input text into an audiovisual speech stream. MikeTalk is built using visemes, which are a small set of images spanning a large range of mouth ...
On the V(subscript gamma) Dimension for Regression in Reproducing Kernel Hilbert Spaces
(1999-05-01)
This paper presents a computation of the $V_gamma$ dimension for regression in bounded subspaces of Reproducing Kernel Hilbert Spaces (RKHS) for the Support Vector Machine (SVM) regression $epsilon$-insensitive loss function, ...
Multivariate Density Estimation: An SVM Approach
(1999-04-01)
We formulate density estimation as an inverse operator problem. We then use convergence results of empirical distribution functions to true distribution functions to develop an algorithm for multivariate density estimation. ...
Learning-Based Approach to Estimation of Morphable Model Parameters
(2000-09-01)
We describe the key role played by partial evaluation in the Supercomputing Toolkit, a parallel computing system for scientific applications that effectively exploits the vast amount of parallelism exposed by partial ...
A Unified Framework for Regularization Networks and Support Vector Machines
(1999-03-01)
Regularization Networks and Support Vector Machines are techniques for solving certain problems of learning from examples -- in particular the regression problem of approximating a multivariate function from sparse ...
Compact Representations for Fast Nonrigid Registration of Medical Images
(2003-07-04)
We develop efficient techniques for the non-rigid registration of medical
images by using representations that adapt to the anatomy found in such
images.
Images of anatomical structures typically have uniform intensity ...
Trajectory and Force Control of a Direct Drive Arm
(1986-09-01)
Using the MIT Serial Link Direct Drive Arm as the main experimental device, various issues in trajectory and force control of manipulators were studied in this thesis. Since accurate modeling is important for any ...
Representation and Detection of Shapes in Images
(2003-08-08)
We present a set of techniques that can be used to represent anddetect shapes in images. Our methods revolve around a particularshape representation based on the description of objects usingtriangulated polygons. This ...
Marriage, Honesty, and Stability
(2003-07-28)
Many centralized two-sided markets form a matching between participantsby running a stable marriage algorithm. It is a well-knownfact that no matching mechanism based on a stable marriage algorithmcan guarantee truthfulness ...
Selecting Refining and Evaluating Properties for Program Analysis
(2003-07-21)
This research proposes and evaluates techniques for selectingpredicates for conditional program properties thatis, implications such as p ) q whose consequent must betrue whenever the predicate is true. Conditional ...
