A Simple and Efficient Estimation Method for Stream Expression Cardinalities
Estimating the cardinality (i.e. number of distinct elements) of an arbitrary set expression defined over multiple distributed streams is one of the most fundamental queries of in...

Estimating the Performance of Cache Replacement Policies
—Caches are commonly employed to hide the latency gap between memory and the CPU by exploiting locality in memory accesses. The cache performance strongly influences a system’...

Gate-level power estimation using tagged probabilistic simulation
In this paper, we present a probabilistic simulation technique to estimate the power consumption of a cmos circuit under a general delay model. This technique is based on the noti...

Guaranteed robust nonlinear estimation with application to robot localization
When reliable prior bounds on the acceptable errors between the data and corresponding model outputs are available, bounded-error estimation techniques make it possible to characte...

Constrained Optimization for Retinal Curvature Estimation Using an Affine Camera
We study retinal curvature estimation from multiple images that provides the fundamental geometry of human retina. We use an affine camera model due to its simplicity, linearity, ...
