An Efficient Boundary Encoding Scheme which is Optimal in the Rate-Distortion Sense
In this paper, we present a fast and optimal method for the lossy encoding of object boundaries which are given as 8-connect chain codes. We approximate the boundary by a polygon ...

Estimability of Spatio-temporal Activation in fMRI
Event-related functional magnetic resonance imaging (fMRI) is considered as an estimation and reconstruction problem. A linear model of the fMRI system based on the Fourier sampler...

Closed-form dual perturb and combine for tree-based models
This paper studies the aggregation of predictions made by tree-based models for several perturbed versions of the attribute vector of a test case. A closed-form approximation of t...

Efficient Linear Macromodeling via Discrete-Time Time-Domain Vector Fitting
We present a discrete-time time-domain vector fitting algorithm, called TD-VFz, for rational function macromodeling of port-to-port responses with discrete time-sampled data. The ...
